Tamiya TT01/TT01E Aluminium Rear Lower Arms for Improved Consistency - JR-TT107-LB by Jazrider  [JR-TT107-LB]

Aluminium rear lower replacement for TT01/TT01E

This aluminum rear lower suspension arm set is made for the Tamiya TT01 and TT01E 1/10 scale chassis, supplied as a light blue anodized replacement for the stock plastic rear lower arms. As direct-fit rear lower arms, the parts are intended to mount to the original hinge points and use existing pins and screws without changing the chassis layout.

In practical setup terms these aluminum arms serve two roles: increase long-term durability compared with stock plastic parts, and alter the rear-end stiffness that affects handling feedback during cornering. Expect a firmer rear geometry that can improve consistency through consecutive runs, while keeping the chassis' original suspension geometry and maintenance routines.

Installation is straightforward for hobbyists familiar with TT01-series maintenance: remove the rear lower arm pins, swap the stock arms for the alloy pieces, confirm the hinge-pin clearance and free movement, then check for any rubbing against body mounts or drive components before running.

When tuning, consider how a stiffer rear lower arm interacts with spring rates, shock damping and toe settings on the TT01/TT01E chassis; the alloy arms change the structural response but do not alter mounting locations or require additional modifications.
