Moto-Obscura Losi XX4 Aluminum Front Bulkhead MO16204
 
Say goodbye to broken front bulkheads on your Losi XX4! This bulkhead is made of high strength aluminum alloy and is hard anodized black. It not only replaces stock plastic hinge pin pivot block but also eliminates the flimsy plastic bumper. This bulkhead uses the bumper mounting points to more securely attach to the chassis, reducing the stresses subjected to the brittle chassis "ears" that often get broken in a heavy crash. 
 
It also features threaded holes for optional set screws to secure the hinge pins in place.
