Primitive - Uni Side Drain Rear Differential Skid Plate (3/16")

Heavy-Duty Protection. Zero-Hassle Maintenance.

For modern Subaru owners, protecting the rear differential shouldn't mean making a mess during your next service. The Primitive Racing Uni Side Drain Rear Skid Plate provides the industry-leading 3/16" aluminum protection you expect, with a strategic cutout designed specifically for late-model differentials with side-access drain plugs.

Whether you're overlanding in an Outback Wilderness or daily driving a Crosstrek on rough backroads, this plate ensures your lowest point is armored against rocks and stumps while keeping your gear oil changes fast and clean.

Product Features

Side-Drain Accessibility: Features a precision-cut access hole that aligns with the side drain plug on modern Subaru differentials. Change your fluid without ever removing the plate.

Wrap Design: This plate offers extended coverage, wrapping around the bottom and sides of the differential housing to protect against lateral impacts and "high-centering" on obstacles.

Rally-Proven 3/16" Aluminum: Laser-cut from premium 5052 Aluminum. It is thick enough to support the weight of the vehicle during a rock strike but light enough to maintain fuel efficiency.

Smooth Sled Surface: The tapered leading edge and countersunk mounting hardware ensure you slide over obstacles rather than snagging them.

Easy Bolt-On Install: No drilling or fabrication required. Uses existing factory mounting locations for a secure, vibration-free fit and easily fits with upgraded exhaust systems and vibration dampener!
