Tamiya 53784 TB Evolution IV Blue Anodized Aluminum Rear Upright  [53784]

Stiffen Your Rear End with Tamiya Aluminum Uprights

The Tamiya 53784 Aluminum Rear Upright replaces stock resin pieces, delivering greater strength and a lighter profile for TB Evo IV and TRF415 chassis. Its blue anodized finish gives a clean race-ready appearance without adding excess mass.

Benefits Over Resin

Aluminum uprights resist flex more than resin, which improves stability and handling through fast corners. The lighter component reduces unsprung mass and can enhance acceleration and steering responsiveness during competitive runs.

Fitment and Quick Installation

The kit ships with the screws and mounting parts needed for a straightforward swap so you can return to the track quickly. It fits TB Evo IV, and can be fitted to the TRF415 when used with the Reversible Lightweight Suspension Set (item no. 49346).
