Put your Mustangs power down to the pavement with both wheels using this Yukon Dura Grip Differential with Composite Clutches for Mustangs with an 8.8" Rear Axle and 31 Spline from CJ Pony Parts! The Mustangs stock differential is great for everyday driving and comfort but doesn’t quite get the power to the road for a good launch.

Features and Benefits:
- Fits Ford 8.8” with 31 spline axles
- 4-spring clutch style positraction
- Forged 4320 steel internal gears
- Fully rebuildable

When you punch the gas from a complete standstill, the stock differential does little except trying to figure out which wheel to give power, giving you a slow start filled with tire smoke. The Yukon Dura Grip positraction differential gives you improved traction off the line by providing equal power to both drive wheels. With aggressive, yet smoother traction, this positraction differential gives your Mustang the performance you need.

The Yukon Dura Grip differential has been manufactured to fit Ford 8.8 rear ends with a 31 spline. The carrier features a 4-spring design with a composite clutch-style limited slip for better traction, and more strength. The teeth for the internal gears are cut from forged 4320 steel for stronger, longer-lasting build quality. This differential is completely rebuildable, allowing for repairs and performance modifications without buying a whole new differential.

Please Note: This differential will not work with independent rear suspensions.

*Yukon recommends using a high-grade GL-5 gear oil and Yukon LSD (Limited Slip Differential) additive for smooth operation and longer life. Synthetic oil may be used but could cause aggressive or noisy operation.
