Ready to upgrade your Tamiya BBX buggy? This is a direct replacement transmission housing set made from aerospace-grade 7075-T6 aluminum. Why upgrade? The stock plastic housing can flex under power, affecting gear mesh and causing wear. This CNC-machined aluminum piece is incredibly strong and rigid, which keeps your gears perfectly aligned for smoother, more efficient power transfer and less wear over time. The black anodized finish looks awesome and helps with heat dissipation. It's a direct bolt-on for the Tamiya 1/10 BBX (BB-01 chassis, kit #58719). Installation is straightforward if you're familiar with RC builds. This is one of those 'must-have' hop-up parts for serious bashers and racers who want maximum durability and performance from their BBX. Just be aware it's just the housing set – you'll transfer all your existing gears and components over into this stronger home.
