Each set includes everything shown in the pic, 2 large 15x28x7 diff bearings, 4 brake actuator bearings installed, a 62 tooth top plate, front and rear uprights with large mounting feet for strength, 8 mounting bolts, 4 o-rings, and a new aluminum top brace to replace the stock plastic brace that goes from the center diff mount to the clutch housing. The center diff mount set for the LOSI 5ive T 2.0 also uses the stock brake bolts and hardware, and has pockets milled to capture the brake bolt nuts for easier assembly.
