Yukon Gear Dura Grip Positraction for GM 7.5in & 7.625in 26-Spline, 3.23+ Ratio

Fits select 1972-1992 Buick, Chevrolet, GMC, Oldsmobile, and Pontiac vehicles with GM 7.5" or 7.625" 10-bolt rear ends (26-spline axles, 3.23+ gear ratio).

The Yukon Dura Grip (YDGGM7.5-3-26-SM) is a clutch-style limited slip differential (LSD) designed to deliver smooth yet aggressive power transfer. By replacing an open differential, the Dura Grip eliminates single-wheel spin and provides the traction needed for street performance, drag racing, and light off-road applications. This unit is fully rebuildable, allowing for a long service life through multiple gear sets or vehicle builds.

Construction features a high-strength nodular iron case to resist deflection under load and forged 4320 chromoly spider gears that are precision-cut for maximum tooth strength. The internal composite clutches provide a firm engagement while remaining quiet during daily driving maneuvers. Assembled in the USA, every unit undergoes rigorous testing to ensure it meets strict tolerances for fitment and performance.
