Description

It is engineered for long life and is completely rebuildable, featuring a high-strength nodular case, forged 4320 chromoly spider gears, and composite clutches for unmatched performance. This differential is specifically designed to fit GM 12-bolt applications with 30 spline axles and for 4.10 gear ratios and up. It is proudly assembled in the USA and backed by extensive product testing and state-of-the-art software design. The Yukon Dura Grips utilize 4320 chromoly spider gears for ultimate durability, and their gears are cut to provide the strongest teeth possible. Yukon recommends the use of high-grade non-synthetic GL-5 gear oil and their specific LSD additive (Part number OILADD) for optimal long life and smooth operation. The use of synthetic oil is not recommended, as it may lead to aggressive or noisy operation.
