Mud Deflector Rearend Fill Tank

The Mud Deflector Rearend Fill Tank by WEHRS MACHINE is a rivet-on protective component designed for rear-end housings on performance and off-road vehicles. This compact deflector shields the differential fill plug area from mud, water, and road debris that can compromise seal integrity and allow contamination into the gear oil. Built for racers, off-road enthusiasts, and serious drivers who demand durability in harsh conditions, this part prevents costly differential damage caused by environmental exposure.

Manufactured from molded plastic in gray, the Mud Deflector features a rivet-on attachment design that secures directly to the rear-end housing without permanent modification. The plastic construction provides a lightweight, corrosion-resistant solution that won't rust or degrade over time, even when exposed to moisture and salt. Its compact footprint—measuring 2.8 x 1.2 x 6.2 inches—fits seamlessly into the rear-end geometry while directing splashed mud and water away from critical fill ports and breather areas where contamination can occur.

This deflector is ideal for bracket racing, desert racing, trail running, and any application where the vehicle encounters muddy terrain or water crossings. Installation is straightforward—the rivet-on mounting requires no drilling or welding, making it accessible to both professional shops and DIY builders. Whether protecting a stock rear end or a high-performance unit, the Mud Deflector Rearend Fill Tank is an essential accessory for maintaining differential longevity and preventing gear oil contamination in demanding environments.
