Description

RCI Offroad Rear Differential Skid Plate | 4Runner, GX & Land Cruiser

Heavy-Duty 3/16" Steel Armor. Direct Axle Clamping. Made in the USA.

The Ultimate Defense for Your Rear Axle

The RCI Offroad Rear Differential Skid Plate is engineered to safeguard one of the most vulnerable and expensive components on your rig. On many Toyota and Lexus SUVs, the rear differential hangs low, making it a "rock magnet" on technical trails.

Built from CNC-cut and brake-formed 3/16" steel, these plates are custom-fit for Toyota 4Runner, Lexus GX, and the new Land Cruiser 250. Whether you have a KDSS-equipped model or a standard suspension, RCI provides a precision-engineered solution that installs in minutes.

The Problem & The Solution:

The Pain: A single rock strike can crack your differential housing or shear off a drain plug, leading to a catastrophic oil leak and a multi-thousand dollar repair bill.
The RCI Solution: Our skid plate features a robot-welded construction and a taller rear flange (2022 update) that encapsulates the housing. It includes a heavy-duty black powder coat to fight corrosion and integrated drain holes to prevent mud build-up.

Key Features: The RCI Differential Armor

Robot Welded

Fully fixtured and robotically welded for industry-leading consistency and strength compared to hand-welded alternatives.

Revised Clamping

The latest 2022 update features an improved clamping mechanism that secures the plate even more tightly to the axle tube.

KDSS Specific Options

We offer dedicated versions for KDSS-equipped 4Runners and GX 460s to ensure zero interference with the hydraulic lines.

Debris Drainage

Strategically placed laser-cut slots allow water, mud, and small rocks to escape, preventing internal rust and weight gain.

American-Made Durability

We don't cut corners. Every RCI Diff Skid is manufactured in the USA from heavy-duty steel. It is designed to slide smoothly over obstacles rather than hanging up, thanks to the precision brake-formed angles.

Real Owner Feedback ★★★★★

"Living in Colorado, the rear diff on my 5th Gen 4Runner takes a beating. The RCI skid was a breeze to install—took me maybe 15 minutes. I've dragged it over several rocks now, and while the powder coat has some battle scars, the differential itself is pristine. This is mandatory gear for anyone wheeling a Toyota SUV."

Frequently Asked Questions

+ Will I lose significant ground clearance?

No. RCI has designed this skid to hug the differential housing within 1/4 inch. You only lose the physical thickness of the steel (3/16"), ensuring your off-road capability remains virtually unchanged while gaining maximum protection.

+ How do I know if I have KDSS?

KDSS-equipped vehicles have significantly larger sway bars with hydraulic cylinders. If you have a 4Runner Trail/Off-Road or a Lexus GX 460, check for thick hydraulic lines running toward your sway bar. It is critical to select the KDSS version to avoid interference.

+ Can I still change my diff fluid with the skid on?

Yes. The design includes a specific cutout for the differential drain plug, allowing you to perform routine maintenance without removing the skid plate.

+ Does this require any drilling?

No drilling is required. The RCI skid plate uses heavy-duty clamps that secure directly around the axle housing. This makes it a 100% bolt-on modification.

+ Will this fit a 2024+ Land Cruiser (LC250)?

Yes. RCI has confirmed fitment on the 2024 Land Cruiser (1958 and other trims) as well as the 2025+ 4Runner. Select the 2025+ model option for the correct fitment.

Prop 65

California Residents

Prop 65 Warning- Product may contain chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. For more information, go to www.P65Warnings.ca.gov

Proposition 65 is a California law passed in 1986. Its goals are to protect drinking water sources from toxic substances that may cause cancer and birth defects and to reduce or eliminate exposures to those chemicals generally, for example in consumer products, by requiring warnings in advance of those exposures.

The regulation requires the State of California to revise and republish yearly a list of chemicals known to the State of California to cause cancer or birth defects or other reproductive harm. The current list contains over 900 naturally occurring and synthetic chemicals. This regulation also requires manufacturers to place warnings on products that contain any of the chemicals listed by the State of California. No other states require warnings of this nature, and products with Prop 65 warning language are legal to sell in all states. Detailed information regarding requirements for compliance to the California Prop. 65 is can be found at: www.P65Warning.ca.gov
