Redesigned front/rear diff bulkhead block set produced from tough, rigid composite product is strengthened for better bearing sitting and enhanced tightness about the differential and pinion. The diff bulkheads fit the bigger and more powerful 13x20 diff situation ball-bearings. The bulkheads could be the mounting point for several suspension system components, and also the housing includes Labyrinth Dust Covers™ to keep dust out from the bearings. The universal design allows the diff bulkhead block become set up at either front side or straight back ends associated with the buggy. Comfortable access to both front part and back differentials makes maintenance a piece of cake. Fits XB808.
