Trail Ready 28 Splines Grizzly Mechanical Locking Differential Ford 8 Inch Rear Axle Heavy Duty Design Built To Lock Down Hard On Rocky Terrain And Dominate The Drag Strip

28 Spline Grizzly Locking Diff for Ford Rear Axles
✔️ Forged 8620 steel internals deliver solid lock

This mechanical unit pins your Ford rear end for sticky hook up on the strip or dirt trail. Designed as a single purchase box, it locks both half shafts together to stop tire spin while still spinning freely during normal highway turns.

✅ Patented cutout design reduces stress under hard loads
✅ High strength 8620 forged gears resist shock impact
✅ Sealed rubber lips block mud water and debris ingress
✅ Direct bolt up layout matches stock crossmember bolts

💡 Why do aftermarket clutchless lockers outperform limited slip units on steep inclines? Swapping to a full locking setup eliminates power split compromises when navigating loose surfaces.
- Heel contact angle stays constant across all gear ratios
- Rugged needle bearings handle sudden driveline shock loads
- Straight forward spline connection provides handy service access
