Tamiya 53975 - TRF501X Rear Shock Spring Set  [53975]

Rear Spring Upgrade for Your TRF501X

The Tamiya 53975 - TRF501X rear spring set supplies three matched pairs of colour-coded springs - Hard, Medium and Soft - so you can quickly tune rear-end stiffness. These springs make it easier to adapt your setup between high-speed straights and tighter corners.

Simple Colour Coding for Setup Work

Each spring pair uses a distinct colour to simplify setup changes and testing. Hard springs increase rear stiffness for more stability, medium springs offer a neutral balance, and soft springs add compliance for extra grip.

Made to Match TRF501X Shock Layout

Specifically produced for the TRF501X suspension layout, these springs fit standard shocks and provide reliable, repeatable tuning steps for racers and enthusiastic hobbyists.
