The Tamiya 54692 TRF419 Rear Upright E Parts are intended to improve the strength of the rear mounting points and deliver steadier handling under load. Ideal for racers and modders aiming for consistent lap times.
By thickening the upper arm mounting area, these uprights reduce the chance of failure from sudden impacts, helping preserve rear alignment during spirited driving.
The TRF419 E Parts permit 0.5mm adjustments to the rear tread width, allowing careful tuning of rear grip and turn-in behaviour to match tyre choice and track conditions.
They fit a selection of Tamiya models including TA07, TA06, TB04, TB Evo6, TA05 Ver II and both TRF418 and TRF419 chassis, making them a flexible upgrade option.
