Yukon Dura Grip Positraction LSD for GM 7.5in/7.625in, 28-Spline, 3.23+ Ratio (1972-2005 Select GM/Isuzu)

The Yukon Dura Grip Positraction limited slip differential (LSD) delivers smooth yet aggressive traction for select 1972-2005 GM and Isuzu vehicles equipped with 7.5" or 7.625" 10-bolt rear ends. Designed to handle diverse terrain and high-performance street applications, this unit replaces a factory open differential to eliminate inconsistent power delivery and ensure both tires hook up when needed.

Engineered for maximum service life and strength, the Dura Grip features a high-strength nodular iron case and forged 4320 chromoly spider gears. The internal composite clutches provide the necessary friction for a firm grip while maintaining the quiet operation required for daily driving. Unlike many disposable units, the Dura Grip is fully rebuildable, allowing you to maintain peak performance for the life of the vehicle.
