JK Rear Diff Skid (RDS) for Rear JK Dana 44
The JK Rear Diff Skid (RDS) is a heavy duty skid designed to protect the JK rear differential and provides a smooth surface for you to slide over obstacles. All components are CNC laser cut and formed by a CNC press brake for a precise fit. We proudly fabricate and hand-weld this product in the USA.
As any rock crawling enthusiast will tell you, every inch of ground clearance matters. Anything on your Jeep's underside that can be smooth should be, or it's likely to catch on an obstacle. Our JK Rear Diff Skid (RDS) is CAD designed with 3D modeling to retain every bit of possible ground clearance for critical protection you need on the trail. Additionally, you gain clearance to any adjacent skid plates.
If you find yourself watching the Lite Brite YouTube channel, and come across their 2019 King of the Hammer’s videos… this is one of the many pieces of metal you will hear banging against — scratch that, breaking — some of the rocks in Johnson Valley underneath their JL (note that it is a JL M220/44 on their rig in this video)

We build the JK Rear Diff Skid (RDS) from a combination of 1/4" and 3/8" thick steel. This diff skid ties into multiple locations on the differential flange, as well as clamping tight to the snout of the differential. As a result, you will distribute any force -- such as the weight of the vehicle on a rock -- over a much larger area. This skid also extends your coverage to the pinion seal and yoke/flange where the rear driveshaft attaches.
*This skid is designed and recommended for use with our HD JK 44 Diff Covers*
Included with purchase:
(1) Rear Differential Skid Plate with Top Clamp
(2) Full Installation/hardware Kit
Do I need to empty my differential fluid before installation?
In our experience, no. The factory gasket in addition to the very thick/ rigid flange on our HD Diff Covers has not leaked any fluid when removing the lower bolts on the cover, as long as the upper bolts are left in place during installation.
This ties into the diff cover; will it cause the gasket to begin leaking fluid if hit hard enough?
In our experience, that would be unusual. When properly torqued with a good gasket, the clamping force of the differential cover bolts along with a very thick/ rigid flange. This prevents most impacts from compromising the integrity of a good gasket/ seal between the cover and differential. Our diff skid extends so far forward, it arguably offers more leverage than the diff cover itself. This is why the pinion/ snout clamp components and hardware are so substantial.
