RSG Rock Sliders 5th Gen 4Runner

RSG Bulletproof Bolt-on Rock Sliders, Install on TRD Off-Road 4Runner

There are a lot of rock slider options out there. I went with RSG Metal Works out of Colorado. I will cover my reasoning for this choice, the options, and features, my experience with the vendor and the install on a 2018 4Runner TRD Off-Road (no KDSS).

True confession, this was my first set of rock sliders. There are not a lot of rock obstacles where I live, but I plan on hitting some other trails out of town, like in southern Utah this summer, so I made the leap. I chose the RSG bulletproof angled slider with the top plate and powder coat. I had only read good comments about the company and product. I also liked that the products were generally already built and ready to ship. It was nice to have some options to choose from, as well.

The top plate and powder coat

My logic for the top plate was to make a bit of a step out of it for people and pets (this is $100 extra).  I like the look of the angled slider better and it gives you a little more clearance.

As far as the powder coating (also $100 extra), I was kind of on the fence but went with it and it does look spectacular. My only concern is having to touch it up and repaint it later once it is scraped and scratched.  If you plan on scraping these on a regular basis, you might want to consider the bare metal and just paint them with some black Rust-Oleum or similar product.

I think this would be much easier to repaint and keep looking nice and new than trying to touch up powder coat. They are rock sliders, so you might not be too concerned if they show some battle damage. I appreciate the options provided and am very pleased with the final product I received.

Where you can buy these sliders


Ordering and shipping were professional and quick. I ordered one day, the sliders were shipped the next day and I received them in two days. From the day I ordered them, they were in my garage three days later.

Shipping cost was $108 for my order, but this can vary by your location. With the FedEx shipping, I was able to divert the shipment to a FedEx office where I could pick them up at my leisure, no worries about being home for the delivery that way.

RSG sent texts and e-mails every step of the way and provided a FedEx tracking number. They came in two separate boxes with the packing materials you can see in the picture.

All went seamlessly.


Unboxing RSG Rock Sliders

Specs from the manufacturer:

  • Works with KDSS or NON-KDSS vehicles
  • Standard rear kick out
  • 2″ Main tube for increased strength
  • 1/4″ Mounting plates
  • Stronger 4 leg design
  • Bolts to factory mounting locations on the frame with supplied hardware
  • Approximately 100 pounds per set
  • Available from bare metal or powder coated


RSG Tools and Hardware

One of the two shipping boxes will be labeled with a hardware sticker. That slider will have 23 13mm bolts taped to the slider.  You can see what the bolt looks like in the picture above. The shorter 12mm bolt is the bolt you will remove from each side before you start the install. They are holding what I believe are brake lines.

Whatever it is, it needs removed and then later replaced during the install. This can be viewed in more detail in pictures below. The only tools you will need are a 12mm socket, 13mm socket, and a socket wrench.


4Runner Brake Lines

Pretty much the first step, besides washing off the area where the slider will bolt onto the frame, is removing the above 12mm bolt from each side, as the slider will slip under this clamp and then you will bolt it all back together with a 13mm bolt once the slider is in place.


The 5th generation Toyota 4Runner comes with pre-threaded holes in the frame to attach running boards, nerf bars and rock sliders with relative ease. The RSG sliders are made to line right up with the factory holes in the frame.

The best method to get started would be to have a buddy hold one end up, while you get a couple bolts threaded in the other side, then move over to the other side and thread a couple more bolts in to secure the other end.

If your buddy doesn’t answer the phone, you can hold one end up with a sturdy box, jack or some other strong object, then use your leg to hold the other end up while you get those first bolts started.

Whatever method you use, be careful, it is pretty heavy. You don’t want to injure yourself, or the rock slider paint job (yet).


RSG Slider Install 4Runner - Bolts

There will be 12 bolts on the driver side and 10 on the passenger side. Place the smaller locking washers on the bolts first, then the larger flat disc washers on bolts. Put a couple bolts in on each side of the slider into the frame to keep it supported while you bolt in the rest.

Leave them all just a little loose until you get all the bolts threaded in, then you can tighten them all the way. I chose not to use Loctite at this point as I plan to let them settle in and then tighten them a little more in a couple weeks. I really think that will do the trick.

If I am proven wrong, I can always go back and hit them with the Loctite. Again, you will replace the 12mm bolt holding (what I think is) the brake line on each side with the provided 13mm bolt. You can see the completed brake line re-attachment with the clamp in the picture above.

This will take place on both driver and passenger sides.


RSG Slider Install 4Runner - Socket

There are a few bolts on the top end of the sliders that are a little tricky because of limited space.  A large socket wrench is likely to hit the body of the truck and not let you line up to the bolt.

I used a smaller socket wrench on theses, which did squeeze in there (see picture).  You could use a standard wrench or a crescent wrench also.  It’s not horribly tight up there, but you might have to switch to a different tool to get those top bolts in, so don’t be surprised.


RSG Slider Install 4Runner - 4Runner KDSS

The driver slider has a huge cut out that I believe is to install around the KDSS system, as I see no other reason for it. You can see the large gap provided in the slider in the picture above.  This picture also highlights the supports on the slider that are covered by the top plate.

If you have the KDSS suspension,  feel free to comment on how that affects the install.  I imagine you might have to remove a few more bolts and re-install them, similar to the brake line clamps.


RSG Bulletproof Sliders Top View

That is it, as far as the install!  Even if you are not overly mechanical or handy, this is a pretty straightforward install. You should be able to do it yourself and save some money for you next mod.


RSG Bulletproof Sliders (Rock Slider/Steps)

The top plate makes a nice platform to use as a step.  My wife is 5’ nothing, so she can use it in combination with the grab handle to pull her self into the truck.  It also makes a nice step to access the roof rack.  You will want the door open so your knees have room while standing on the platform to reach the roof.


rsg-frontRSG Bulletproof Sliders - Back View

The kickout with the top plate makes an excellent step for the back seat. Whether it’s a kid or a dog, the plate is wide and makes a nice platform, preferably used when not caked in mud.

On a side note, these like probably any other rock sliders, are going to be mud magnets.  It’s not a huge deal, but just know the tires will kick mud onto the top of the sliders.  If you live on a gravel or dirt road, you might want to really think this through, as it could be annoying as your everyday driver.  If you live on the pavement, I don’t think it will be much of a concern, just an occasional wash.


RSG Bulletproof Sliders - Close Up

The kickout extends out past your rear tire to protect your rear quarter panel when driving around large rocks. Even with the angled sliders and using negative offset wheels or slightly larger then stock tires, the kick out should extend past those back tires (see picture above).


RSG Bulletproof Sliders - Full View

From this side view, you really don’t see the top plate, they look the same as an open slider and they tuck up nice and close to the 4Runner, leaving lots of clearance and protecting those rocker panels.


RSG Bulletproof Sliders - Logo

Rock sliders are a major purchase with whatever brand you choose and will cost you plenty of coin.  Check out your options and do your research, but I can tell you my experience with RSG was phenomenal.

The product is just well put together and thought out, the inventory is good, communication was great, shipping crazy fast, install had no surprises and I couldn’t be happier.

Check these out as you shop and make your purchasing decision. Enjoy those trails!

Did you go with DOM or HREW?

Great article, it really helped me choose a slider for my 2020 SR5 P. I wanted to be confident in the install before dropping the $$. All the bolts lined up perfectly. I used 2 jack stands and some wood shims and did it solo, took about 4 hours on a hot day. The Jack stands at least gave me something to rest the 50lb sliders on, but it just takes a while to work though all 20 bolts. RSG was a 6 week lead time. I met the UPS guy in the driveway by creeping on him with the… Read more »

John, a question on the install.
Were you able to install the sliders at stock height, or did you use ramps / jack stands?

Go Cougs! I’ve been researching which brand to go with. This is one of the only ones that does the top plate to satisfy the wife and an angle to satisfy me for clearance. Thanks for the review!

I installed my new RSG sliders on Saturday for my 2019 4Runner, no KDSS. I purchased them partly due to this write-up, so thanks for that! I got the angled with top plate, powder coated. Install went fine, but they are definitely heavy. I installed them right over the plastic frame plugs. By the time you tighten all the screws, the slider plate is just about flush with the frame anyways. But, with the slider in place, the factory bolt for the parking brake line was too short to reach the frame hole. No matter what I tried! Luckily I… Read more »

Just received and installed my new RGS rails. About seven weeks with shipping for the powder coated at this point. Customer service as top notch and they always kept me up to date. I know that they recently added onto their shop and that put them behind, so I am sure those delays will start to taper off. Definitely a great looking product, and overall I’m very happy with the purchase. It took me about 4 and a half hours to put them on. I know that part of that is that I’m a little type A when it comes… Read more »

Mine have been backordered. Didn’t find out until after the order was placed. 3 weeks later, still waiting. Not a huge pain, just wanted to give another response on timing as most folks said shipped in 24 hours.

Thanks for the reply John. I love the truck. I drove a Gen 3 for almost 10 years and then passed it to my boys. We still have it and also a Gen 4. Their awesome vehicles. That helps a lot in my decision. I prefer the angled sliders too but I’ll go with the flat with top plate to be more practical. I still think those look really good also. RSG seems like a really solid company. Appreciate all your write-ups. They are really helpful with the mods I have planned.

OK. I ordered my rock sliders with the powder coating and after waiting out the lead time they are on the way. Through research on the web many have said that the plastic plugs on the frame need to be removed in order to allow the slider to be as flush as possible to the frame. It is suggested that this can prevent water, debris, dirt, dust etc from causing rust where they are mounted. Others have suggested using sealers or fluid film treatment but there is no definitive solution that I see other than regular checks (yearly) and treatment… Read more »

We install the sliders over the plugs and leave them in the frame. It’s really your preference if you want them there or not.

We have yet to see any issues with leaving them or removing them.

February 11, 2019 1:51 pm

Great write-up. I just purchased a 2019 Trd off road and am seriously considering these. I love the way these look and would rather spend the extra to get real protection. These would probably be used more for a step than an actual slider. I mainly run fire roads and some light trails but no rock crawling is realistically in my future. I have had a Gen 3 since 2001 and never did it. This is my daily driver/weekend warrior vehicle and for purposes of travel in snow and gravel for the most part. My question is would the flat… Read more »

Good comments. I’ve been going through a zillion youtube videos, forums, review sites – the lot – trying to settle on which sliders I want. Now that I’ve got the head’s up on the KDSS cutout and install, I’ll do some more research. I’ve pretty much settled on the RSG. I think they look good, they’ll do the job (I don’t do heavy rock hopping) and the install should be pretty straight forward. And they are reasonably priced as far as I can see. I’ll update when I get them

I just got my black rsg silders. I gotta say I’m pretty upset. The non kdss side bolted right in like 15 mins and done. The kdss side I figured was going to be a issue. But it went up into place with some wiggling. But now I had to remove the slider and drill out the top holes and a bit on the bottom to get this to fit correctly . Not too happy but it is what it is.

September 14, 2018 9:58 pm

I have a 4Runner with KDSS and am thinking of purchasing these RSG sliders. Can you be more specific about what didn’t fit correctly. I’m not a mechanic and I’m wondering if I can even tackle this.

The drivers side requires you to take off the bolts for the kdss and slide the slider between the frame and kdss. Not super difficult but mine was a bit. I had another friend buy them and his went up and in no problem. Maybe I just got lucky because alot of people dont have the same issue I did. Also the company will work with you if something is not going together right.

Nice! What size tire are you currently running?

July 30, 2018 9:52 pm

Do you have a lift on your 4runner and spacers as well? If so, can you share more about that? I’m looking to make some mods to my ’17 Trail Edition w/ KDSS. Thanks!

July 6, 2018 3:26 pm

Thanks for the great writeup! These look super stout, but I understand they use HREW tubing rather than DOM. Any concerns about strength because of that? Seems like these would check every box for me if they were DOM.

Not sure if you are still in the market for sliders but we do offer a DOM option for an extra $100
Shoot me an email if you’re still in need.

Thanks Jason. I ended up getting a set of your angled sliders with kick out in HREW which I really enjoy! They are definitely stout and look great as well.

June 3, 2018 6:46 pm

I like the angled ones better too. Would the flat ones have been a better step for the wife and doggy?

RSG now has an aftermarket KDSS skid plate that replaces both factory KDSS skid plates. Fits perfect with my RSG rock sliders.

Only difference on installing the Rock Sliders when have a KDSS system is having to unbolt the clamps that hold the KDSS hydraulic lines to the frame and slide the rock slider bracket behind them. A little tight but I used a floor jack and jacked them right into place.

May 15, 2018 11:21 am

This write up and install has helped me make my final decision on sliders. Thank you for a detailed, awesome write up! RSG all the way!

April 27, 2018 6:42 pm

Nick, if anything you’ll probably end up very happy you have your own grinder now too. I couldn’t imagine not owning at least one myself – but then again, I’ve been wrenching and fab’ing for two decades now.

Just installed the same sliders my TRD Off Road, however mine has KDSS. It is actually kind of a pain, it requires a bit of trimming on the lower KDSS skid plate. I had to go out and by a grinder that could handle this. I haven’t seen any install videos or instructions for this, maybe I should post mine. I believe RSG isn’t the only slider with this issue for KDSS vehicles.

Yeah I’m happy with the KDSS system so far, looking to upgrade the shocks and springs soon as well. Yes, there are 2 factory KDSS skids, I only had to trim one of them in order to be able to bolt it back on. I’ve heard you need to do the same thing to install C4 sliders as well.

Other than that the install was easy. And the product is great, the sliders are very well built, hopefully my original comment didn’t seem like a disliked the product, I love it.

April 26, 2018 4:13 am

I’ll tell you right now, I thank you for posting this. RSG wasn’t coming up in my previous searches. I have a detailed excel sheet I’ve created for sliders over the past year, comparing features and prices and company info… but I haven’t pulled the trigger because I couldn’t find something that satisfied all requirements. Now, I’m an overly conscious consumer. I’d rather, and often do, spend a little more with companies that I can really stand behind when it comes to their product, practices, and customer service. RSG so far is delivering on all fronts here. I placed the… Read more »
