XRay Diff Bulkhead Block Set Front - Narrow

Redesigned super-strong FRONT bulkheads are narrower to move the arms more into centerline to generate more traction and to provide a greater range of track width adjustment. The bulkheads have a perfect fit to the updated differential and are reinforced to increase the reliability.

The XB4 bulkheads allow super-fast & easy diff exchange and servicing by dismounting only 4 screws from the front of the bulkhead and bottom of the chassis. This super-fast diff access is available at both front & rear.

The bulkheads have minimized ball-bearing play, resulting in increased gear teeth lifespan and minimized gear stripping.
