Description

The Yukon Dura Grip provides aggressive yet smooth traction. It features a 4-spring, clutch-style positraction with internal gears manufactured using forged 4320 steel for ultimate durability. It is fully rebuildable and assembled in the USA. Yukon recommends using high-grade non-synthetic GL-5 gear oil and Yukon LSD additive (part number OILADD) for long life and smooth operation. The use of synthetic oil is not recommended and may result in aggressive or noisy operation.
