Body Mount Chop for 34″ Tires on 5th Gen

With the addition of bigger tires, you will need to do some trimming. There was quite a bit of hesitation when we decided to go with the 34″ tires. But, at the end of the day, we are glad that we did. The 34″ tires give it a pretty mean stance.

We decided to go with the 34″ Toyo Open County All Terrain 2 tires (285/75R17), and the 17″ Fuel Anza Bronze wheels on the Trail Premium.

Our next step after getting these installed was straight over to the body shop to have the Body Mounts Chopped. Once we have the body mounts chopped off, we can start trimming some of the plastic from inside the wheel well.

Jump to the step by step install on the body mount chop kit by Metal Tech 4×4.

What is like driving with 24″ tires? It is quite a bit different compared to 31″ tires. That is for damn sure. When we first pulled off with the new tires, you can tell it was a bit sluggish.

We have a TRD Intake combined with the Magnaflow Exhaust for performance and it didn’t seem to make much a difference compared to when we first installed them.

I knew there was going to be a difference but I didn’t know it was going to be as much as it is. The sluggishness goes away after you get going, but off the line, there is no power.

It is a good thing my commute to work every day is less than a mile. My office is across the street from my house which makes for a nice slow comfortable ride. With that being said, it doesn’t bother me that much.

It really depends on how much you off-road. We go out as often as we can and we don’t always write blog posts for places we go. And, sometimes we hit the same places that we have gone in the past, so it does not make much sense to write another post on them.

17″ Fuel Anza Bronze Wheels

These wheels are stunning. There are a few Tacoma and Tundra owners out there with these wheels. But as of right now, we are the only white 4Runner with these bronze wheels.

They are not a true beadlock, although Fuel does make one wheel that is a true beadlock. Also, the beadlock on these one-piece wheels are not removable. If you do paint or remove these beadlocks, it will void your warranty.

  • Wheel Size: 17X8.50
  • Bolt Pattern: 5×139.7
  • Finish: BR -BRZ
  • Bore: 108
  • Offset: -6
  • Backspace: 4.500
  • Weight: 25
  • Lip Size: 2.68

Body Mount Chop

The body mount chop is a well-known mod if you are running larger tires. If you have a 3″ suspension, like the stage 2 Icon suspension, you can run 33″ tires and be fine. In most cases, no modifications are needed but it depends on the exact size of your 33s.

If you go with 34″ tires with a 3″ suspension lift, you will need to chop your body mounts. Furthermore, if you are running 33″ tires or even 32″ tires with a leveling kit, you may need to chop your body mounts.

On a previous post, we installed 31″ KO2’s on a 3″ Pro Comp leveling kit and there is plenty of room. No need for the body mount on this one. 31″ tires really fit under anything. Even a 2″ in the front and 1″ in the back, 31″ tires will have plenty of room.

What is a Body Mount?

The 5th Gen 4Runner is a body on frame. Maybe the last of its generation. The frame holds the engine, suspension and the supports the body with rubber bushings, anywhere from 6 to 12 separate points. The body mount and body mount bushings cushion the ride, but over time they break down.

The actual body mounts that we are referring to are underneath both the front driver and passenger side, closest to your nerf bars or rock sliders. These body mounts have a steel casing that encloses the actual body mounts. This body mount encloser needs to be chopped off as it will interfere with your larger tires.

Body Mount Chop + Trimming Plastic Fender Pieces?

NOTE: After trimming off most of the plastic valance cap, the tires are still rubbing on the line where the screw sits. We need to come back in a do a bit more trimming in this area.

There are a couple different places where you will need to modify your plastic fender wheel well parts on top of chopping your body mounts. Some of these are needed in our case and some of these are not. Every 4Runner is different. For whatever reason, you may not need to trim some of the same areas that we will need to trim and vice versa. Every make and model is a little different but everything is pretty similar, so you will get the point.

  1. Plastic Fender Cap – NEEDED
  2. Plastic Rear Fender Cover – PUSH BACK?
  3. Plastic Front Fender Cover – PUSH BACK?

Pictured Above was cutting that we already made for our leveling kit, just to give it a little more room. You can see the uneven cuts from what we had done before. We are going to go a step further with the new 34″ tires. 

You will need to chop and trim up your body. Yes, you will literally need to cut a piece off of your pretty body. The body mount chop will only prevent the inside area (rear of the wheel well) from rubbing. The trimming of your body will need to take place in the front of the wheel well, closest to your grill. By chopping the front of the body fender, you will prevent rubbing on the front of the wheel well.

I want to run 285/75R17’s on my 2017 4Runner TRD Pro, Can I do a 2” toytec lift and get them to fit with trimming and bmc?

I found a good link to video for doing a body chop. This video is associated with a kit you can buy for like $50. It looks simple and I’ll give it a try this summer. Copy the link below into your browser.



Would a 4Runner with KDSS system (Premium Off Road) be able to retain KDSS with a 3” lift? Trying to figure out if I want to spend the money on the KDSS or just go with a TRD Pro and lift. Want to have a 3” lift and run 33” rubber.


3″ ICON lift with adjustable coilovers. Currently have 285/70/17 on the stock TRD Pro rims but am thinking SCS F5s 5o replace. I was told I would need to can mount but I’m hesitant to proceed with buying them if I have to do so.

Any advice would be appreciated if you think I can get away without chopping.

Hello, great article. I just recently purchased stealth custom
Matte Gunmetal / 17×8.5 4.30″ BS 6×139.7
And was also going to add Daystar, Toyota 4Runner 2.5″ Lift/level kit, on my trd off road 2017.
I was hoping to run to 275/70/17, 32.2 inch tire do you think I will have to do any/much chopping in order to fit this tire. Any help you can give me would really be greatly appreciated
Thanks in advance Gerald
