Product Description

The Yukon YDGC9.25-31-1 Dura Grip is a clutch-type limited slip differential built for the Chrysler 9.25 in. rear axle with 31-spline axles, covering a wide range of Dodge Ram 1500, Ram 2500, Dakota, Durango, Ramcharger, Ram Van, Chrysler Aspen, and Mitsubishi Raider applications through 2010. Its nodular iron case and forged 4320 chromoly spider gears deliver the durability needed for daily driving, towing, and off-road use.

The composite clutch pack and 4-preload spring design provide consistent torque transfer to both rear wheels under load, eliminating wheel spin and improving traction in low-grip conditions. The fully rebuildable design adds long-term serviceability, and all-ratio compatibility makes it a direct drop-in for any Chrysler 9.25 in. housing.

Note: This unit is designed for the pre-2011 Chrysler 9.25 in. axle only. For 2011 and newer applications equipped with the ZF-type 9.25 in. axle, use part number YDGC9.25ZF-31-1. Requires non-synthetic GL-5 gear oil and Yukon LSD additive (OILADD). Backed by a 1-year manufacturer warranty against defects.
