Tamiya TA05-R/TRF415/TRF-416 Bridge Suspension Mount 415-01/B1A by 3Racing  [415-01/B1A]

Aluminium bridge mount for Tamiya race chassis

This aluminium bridge suspension mount is an aftermarket replacement designed for assembly on Tamiya TA05-R, TRF415 and TRF-416 chassis. It creates a stiffer mounting point for the suspension bridge to help keep geometry consistent during setup changes and maintenance.

Fitment is limited to the listed chassis, so confirm your car uses the TA05-R/TRF415/TRF-416 bridge layout before installing. The part is machined from aluminium to reduce deformation compared with stock plastic, delivering a firmer pivot where reduced flex is required.

Installation normally involves removing the stock bridge mount and refitting this unit with the existing chassis hardware; check screw lengths and thread engagement as you assemble. In tuning terms the mount helps stabilise suspension geometry so toe, camber and roll-centre adjustments track more predictably between runs.
