Product Description

The Yukon YDGC9.25ZF-31-1 Dura Grip limited-slip carrier upgrades the rear 9.25" Chrysler/ZF differential with a durable, torque-sharing design built for modern Ram 1500 trucks (2011-2025) and other compatible applications. Featuring 31-spline axles, 4320 chromoly spider gears, and a friction-clutch limited-slip, it enhances traction smoothly under load--ideal for towing, off-road, or slippery road conditions.

Its rebuildable nodular steel housing and composite clutch packs ensure long life and reliable performance. Installation follows factory procedures with no special fitment required, while the slip-biased design blends capability with everyday drive comfort. Please use Yukon's recommended gear oil and friction modifier--avoid synthetics to preserve functionality.
