B8 Rear Arm Reinforcement and Gearbox Support

This aluminum rear suspension arm mount and gearbox support is an aftermarket upgrade for the B8 rear assembly positions on the Tamiya 1/10 buggy models listed below. It stiffens the rear mounting point and creates a reliable surface under the gearbox area, which helps reduce chassis flex during cornering and under heavy loads.

The piece is made to directly replace the stock B8 rear mounts so you can retain the factory layout while gaining material stiffness. Fit it when you need a crisper rear response for tuning traction or when gearbox area stiffness is required. Installation will need partial disassembly of the rear suspension to access the B8 mounts; double check alignment before final tightening.

Compatibility

  • Tamiya Thunder Shot
  • Tamiya Thunder Dragon
  • Tamiya Fire Dragon
  • Tamiya Terra Scorcher

Great stuff. Love the upgrades. Wish they did more though, love jazzing up my cars
Only standard hand tools are typically required to remove the rear subassembly and swap in the mount. A set of metric hex drivers and a torque-aware driver for final tightening are recommended for best results.
Aluminum generally withstands repeated loading better than softer plastics, so it can extend service life in high-stress rear-end applications, though proper installation and maintenance remain important.
Yes, this mount complements other rigidity upgrades. Use it alongside braces or upgraded bulkheads to tune overall chassis stiffness, but evaluate handling changes incrementally to find the right balance.
