The Yukon Dura Grip is a four spring, clutch driven limited slip with roots going back to the factory dura grip positractionunits found in 60’s & 70’s GM muscle cars. These units feature Raybestos composite clutches for longer life, while still providing strong lock-up ability for greater traction.
