Tamiya TT-01 Rear Lower Arm TT056 Aluminium Upgrade by GPM  [TT056]

Precision alloy rear lower arm for TT-01 platforms

Part number TT056 is an aluminium rear lower arm engineered for the Tamiya TT-01 chassis. The component uses a machined aluminium alloy profile to increase rigidity at the suspension pivot compared with stock plastic arms, supporting tighter rear geometry and extended lifecycle under typical hobby use.

The kit is supplied with the complete set of replacement hardware named in the product title: shims, collars, E-clips, pins and screws for direct substitution of the factory lower arm. Installation assumes standard TT-01 mounting points and does not require structural chassis alteration.

Recommended installation procedure: remove the rear suspension link and original arm, inspect and transfer bearings or linkage elements as necessary, then secure the aluminium arm with the supplied pins and E-clips. This part is intended as a performance-minded chassis upgrade to stabilise rear-end behaviour and reduce plastic arm wear during setup and regular running.
