Description
Description
SPE S550 Composite Differential Lockout System
The stock rubber bushings are great for absorbing NVH, but do nothing for performance applications. Help eliminate wheel hop by adding the SPE Street differential bushing kit for the super 8.8 S550 rear end.
This kit mounts the rear end to the cradle without an increase in NVH like the billet versions. They install on top of the factory bushings allowing for a non-permanent install. No need to replace the entire bushing to get a stiffer mounting system with no NVH. All the benefits of a stiffer complete bushing replacement without the cost and labor involved in replacing them.
Features and Benefits:
- Reduce wheel hop
- Reduce 60-foot times
- Increase control and predictability
- Easy Install
- Non Permanent modification
- Stainless steel crush inserts
- CNC machined Hybrid Delrin bushing material
- Hardware included
