This aluminium rear suspension arm mount and gearbox support is an upgrade part built for the B8 rear assembly points on the listed Tamiya 1/10 buggy chassis. It provides a firmer anchor at the rear of the chassis and a flat support area around the gearbox, which helps cut down on flex when the car is under load and improves the consistency of suspension adjustments during setup.
Designed as a direct swap into the B8 rear mount spots, the component keeps the stock layout while changing stiffness characteristics. Fit this part where you need a stiffer rear end to tune traction balance or to stabilise the gearbox region. Basic disassembly of the rear subassembly is required for installation; always verify fitment on your chassis before torquing fasteners.
