Tamiya 51640 TRF420 Carbon-Reinforced Rear Uprights SP-1640  [51640]

Carbon-reinforced rear uprights tuned for racing

The Tamiya 51640 TRF420 E-Parts, specifically the rear uprights, are aimed at builders who want firmer suspension geometry on their TRF420 chassis. Molded in carbon fiber reinforced plastic, these uprights increase stiffness where it counts to help maintain consistent handling through high-speed corners.

Accurate bearing placement for low friction

The rear uprights feature tightly controlled bearing positions to reduce play and lower rolling resistance. That precise alignment helps wheels track truer and can translate to steadier lap times when bearings and shafts are correctly installed.

Works with 3mm shafts and TRF420 D parts

These uprights accept 3mm diameter shafts, available separately as Item 51637, and they pair directly with TRF420 D Parts (Suspension Arms). That compatibility makes them simple to integrate into a range of TRF420 setups for tailored balance and durability.
