Yukon Hardcore Iron Diff Cover for GM Rear

Description

Product Overview

The Yukon Hardcore Nodular Iron Cover is a premium replacement for GM 9.5″ and 9.76″ rear differentials. Crafted from thick‑walled nodular iron, the cover adds significant rigidity to the differential housing, reducing flex under high torque conditions. The interior surfaces are precisely contoured to promote rapid oil flow, enhancing cooling during demanding off‑road or performance driving. Finished in a durable black powder coat, the cover resists corrosion and wear, while contrasting stainless‑steel accent plates and bolts add a touch of style. High‑quality magnetic drain plugs provide quick, leak‑free maintenance.
