Description

The Yukon Dura Grip Limited Slip Differential is engineered to provide smooth yet aggressive traction for your GM 8.5" or 8.6" axle. Designed with a 30-spline count and compatibility for 2.73 and up gear ratios, this positraction unit enhances performance across various terrains. Constructed with a high-strength nodular case and forged 4320 chromoly spider gears, the Dura Grip is built for ultimate durability and longevity. Its composite clutch design ensures reliable engagement, while the fully rebuildable design allows for future servicing. Proudly assembled in the USA, this limited slip differential is a testament to quality manufacturing and undergoes extensive product testing. Yukon recommends using high-grade non-synthetic GL-5 gear oil and their specific LSD additive (Part number OILADD) for optimal performance and longevity. The use of synthetic oil is not advised, as it may lead to aggressive or noisy operation. For the 8.5" housing, carrier bearing & race part numbers LM102949 & LM102911 are used, while the GM 8.6" housing utilizes LM603049 & LM603012.
