Tamiya TT02 Front Lower Arm Aluminium Upgrade TT2055 by GPM  [TT2055]

Upgraded Front Lower Arm for TT02

This aluminum front lower arm is a direct-replacement part for the Tamiya TT02 chassis, supplied as 1pr and identified by model TT2055. It provides a metal alternative to the stock plastic arm to reduce flex at the control point and to retain consistent mounting geometry during setup and maintenance.

Fitting is straightforward to TT02-spec steering knuckles and hubs, but confirm ball-stud alignment and clearance before final assembly. Use the correct fasteners and torque to your chassis recommendations, and cycle the suspension through its full travel after fitting to ensure nothing binds. Inspect pivot areas and mating surfaces and apply light lubrication where appropriate.

As a tuning component, this alloy arm changes the local flex characteristics and can give a firmer front-end connection that helps camber retention and sharpens initial steering response. Consider it when you need predictable geometry for setup comparisons or when replacing worn plastic arms during routine servicing.

Fit this arm as a like-for-like front lower arm replacement on TT02 builds to maintain suspension geometry and to provide a stiffer mounting point for tuning and regular maintenance.
