Construction & Design

This differential cover is crafted from premium-grade aluminum, chosen for its excellent strength-to-weight ratio and resistance to corrosion. The finned surface design is not just aesthetic; it actively dissipates heat generated by the differential during heavy towing or off-road use, reducing the risk of overheating and premature gear wear. The polished finish adds a layer of protection against rust and environmental damage while giving your Ram a distinctive, high-quality look that complements its rugged character.

Engineered to match the exact specifications of the original equipment, the cover maintains factory tolerances to ensure a perfect fit and reliable sealing. Its robust construction also guards against dents and damage from road debris or trail obstacles.

Installation & Fitment

Installation is straightforward and designed to be a direct replacement for the factory differential cover. No special modifications or tools are required, making it an ideal upgrade for both professional mechanics and DIY enthusiasts. Simply drain the old gear oil, remove the factory cover, clean the mounting surface, and bolt on the Yukon finned aluminum cover using the included hardware. Refill with the appropriate gear oil, and your differential is ready for enhanced protection and cooling.
