The Tamiya 54692 TRF419 Rear Upright E Parts are designed to strengthen the rear mounting area and keep suspension geometry stable under load. They are a solid upgrade for clubs and track riders looking to reduce maintenance between sessions.
The increased thickness at the upper arm mounting surface helps prevent breakages from impacts and keeps the rear end behaving consistently during aggressive laps.
These E Parts let you tweak the rear tread width in 0.5mm steps, enabling precise handling changes to suit different track layouts or tyre choices.
Designed for use with TA07, TA06, TB04, TB Evo6, TA05 Ver II, and the TRF418 and TRF419 chassis, these uprights are compatible across multiple Tamiya platforms.
