RCI Front Skid Plate Install 5th Gen 4Runner

RCI Off-Road Skid Plates 5th Gen 4Runner

Step-by-Step RCI Off-Road Front Skid Plate (KDSS Specific) Installation on 5th Generation Toyota 4Runner

Simply put, skid plates help protect many undercarriage parts of your truck. If you start beating up your factory skids you can expect more than just skid damage. Weak factory skids can lead to structural damage, and other critical working parts like hydraulic lines, gas tanks, radiators, and much more.

Do your truck a favor and protect it with a set of upgraded aluminum or steel skid plates.

If you are looking to see what the installation process is going to take for a full set of skids, this is a good place to start. Our goal is to install literally every skid possible on the 5th Gen. We will be updating this post as time goes on.

RCI Off-Road makes a “Full-Set” that includes the Front, Transmission, and T-Case skid. For most drivers, this should offer plenty of protection but we are going the extra mile here.

Just remember to order the KDSS version if you are running KDSS.

If you order the non-KDSS version for a KDSS truck, the plate won’t mount up because the KDSS sway bar will be in the way.

Installation Guide

Installing the front skids is very straightforward. Complete Installation for the front took under one hour while the remaining five skids, took just over six hours.

We did need to modify our C4 Fab rock sliders in order for the lower link skids to fit so that’s what took us a little longer. Depending on what skids you install, you may need to modify your rock sliders in order for different skids to fit.

In our install example, we are using all RCI Off-Road.

Step 1: Jack Stands

RCI Off-Road Skid Plates (Front)

Lift the front of your 4Runner with a floor jack, and place front tires on ramps, blocks or jack stands.

Do not use front cross members as a jack point, this may interfere with the installation.

We jacked our truck up and we used a set of homemade wood blocks (jack stand risers) for trucks with higher lift kits.

Step 2: Remove Factory Skids

Step 2: Remove Factory Skid Plates

Remove OEM skid or any other aftermarket skid currently installed.

Note these factory mounting points as the RCI skids will bolt to the same location.

Step 3: Position RCI Skids into Place

Lift Skid Plate Into Place

Using two people or a floor jack, lift the RCI skids into place and loosely install the 40mm bolts with washers into the center mounting holes (the holes with the skid plate risers).

Step 4: Mount the rear bolts

Rear Bolts on Skid Plate

Once the skid is self-supported, install the remaining 40mm bolts with washers.

Install the half-inch nylon spacers on top of the skid plate and then thread the bolts through and into place.

Adjust the plates with the bolts are near as possible to the center of the mounting holes.

Step 5A: Crossmember Supports

Frame Tube Mount Brackets

If you are installing your RCI skids with factory skids mounted, you will have a simple plug-and-play kit.

Because we previously installed the TRD skid, we removed the factory frame tube mount spacer brackets (pictured above).

If you are installing the RCI skids with factory skid plates currently installed, you will retain the use of these spacer brackets and it will be a very easy plug-n-play bolt-on install.

Step 5B: TRD Pro Conversion

Mounting Front Bolts on Skid Plate

If you do not have the tube mount and bracket mentioned previously, the front of the RCI skid will sit about 1″ away from the recommended mounting point on the cross member.

The recommended factory mounting point per the instructions is to mount to that tube mount bracket, so with the bracket gone, you need to add a spacer of your own.

Instead of mounting this bolt to a bracket, there is a hole that goes straight through the cross-member. This allows you to slide the bolt all the way through and secure the nut on top.

We found an extra set of nuts, bolts, and spacers provided from our previous install.

If you don’t have anything lying around, go to ACE Hardware or Home Depot and find any 1″ spacer and if it’s not perfect, you may need to add washers to make up a 1/8″ or so difference.

Step 6: Transmission Skid

Rear Bolts on Skid Plate

If you are installing the transmission plate supplied from RCI Off-Road in addition to the front skid plate, you will need to leave approximately a 1/2″ of rear bolts unthreaded to allow the transmission skid to slide and lock into place.

Step 7: Check the fitment

RCI Off-Road Skid Plates (Front)

Check the fitment and clearance and proceed to fully tighten all bolts with a 13mm wrench to OEM torque specifications. 23ft lbs.

The front RCI skid plates feature an oil filter access port, check and ensure these bolts are tight.

Hi Brenan. Do you have the transmission skid plate also? If so, does it cover the catalytic converter enough to prevent it from being stolen? Having some of these stolen in my area.

Yes and no. The skid plate will serve as some added layer of protection but if someone really wants it, they will get it. Here are some some shots showing the catalytic converter // front pipe.

I think you mentioned why but I’m still confused. I just installed on my non-kdss 2018 with factory skids. The front mounting points line up but aren’t flush. Like you said there’s about 1 inch in between the skid and mounting point. Weird! I’m a suppose to add a rubber spacer like they supplied for the rear mounts? Thanks
