The Strange Engineering Aluminum Ultra Support Cover is a must-have upgrade for any high-performance GM 12-bolt rear end. This cover does more than just seal your differential; it provides critical structural support to the main bearing caps, preventing cap walk and gear deflection under heavy acceleration. Machined from high-quality aluminum, this cover is both lightweight and incredibly rigid, making it the ideal choice for drag race and high-torque street applications.
When pushing your GM 12-bolt to its limits, standard stamped steel covers simply cannot provide the necessary rigidity. The Strange Engineering Ultra Support Cover acts as a girdle, tying the bearing caps to the cover to minimize movement. This results in crisper power delivery and significantly reduced risk of catastrophic gear failure. If you are serious about your drivetrain performance, this cover is an essential addition to your build. Explore our full catalog of differential upgrades and performance parts at GGCRACING.
