Its nodular iron case and forged 4320 chromoly spider gears deliver the durability needed for daily driving, towing, and off-road use.\u003c\/p\u003e\u003cp\u003e 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.\u003c\/p\u003e\u003cp\u003e 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).
