Rear Suspension Arms Aluminum Upgrade for TAMIYA TT-02B JR-TT2B05-LB by Jazrider  [JR-TT2B05-LB]

Stiffer aluminum rear arms tailored for TT-02B setup work

This JR-TT2B05-LB aluminum rear suspension arms set serves as an aftermarket replacement for the TAMIYA TT-02B chassis. The machined aluminum construction produces more consistent dimensions than stock plastic parts and creates a firmer platform for suspension linkages at the rear.

Install this set to reduce unwanted compliance during tuning or when replacing aged plastic arms. The light blue anodised finish helps resist surface wear and speeds up part identification during setup changes. The arms attach to the standard TT-02B mounting points and reuse the existing chassis hardware for a straightforward installation.

In setup terms, reduced arm flex gives more repeatable toe and camber under cornering, which can be beneficial when dialing in damper and anti-roll bar settings. Expect a crisper response to adjustments, and after initial runs, verify fastener tightness and check clearances at the hub carrier and shock tower to ensure full travel.
