The Yukon Gear Dura Grip is a high-performance positraction limited slip differential (LSD) engineered for aggressive traction and smooth operation across diverse terrains. Designed for the Dana Spicer 70 rear axle, this unit replaces an open or worn-out differential to provide the grip necessary for heavy-duty towing, off-roading, and street performance.

This 4-pinion LSD is built with a high-strength nodular iron case and features forged 4320 chromoly spider gears for superior durability under high-torque loads. The internal composite clutches deliver consistent engagement and are fully rebuildable, ensuring a long service life. This unit is compatible with 32-spline axles and is designed for 4.10 and down gear ratios (numerically lower), including compatibility with thick gears.
