This is a replacement XRAY Differential Bulkhead, and is intended for use with the XRAY XB808 1/8 buggy. This bulkhead is used on the front or rear of the vehicle. This redesigned bulkhead is made from rigid & tough plastic composite and has been strengthened for better bearing seating and improved stiffness of differential and pinion. The bulkheads are the mounting point for all suspension parts, and include Labyrinth Dust Covers™ for the bearings to keep dirt out. Easy access to both front and rear differentials makes maintenance super easy. Intended for use on the front or rear.
