Tamiya TT01 Alloy Rear Lower Arm by GPM TT056  [TT056]

Alloy rear lower arm for TT-01

This is an RC-scale rear lower arm engineered for the Tamiya TT01 platform, produced by GPM as part number TT056. The part uses aluminium alloy to offer a firmer mounting point for the rear suspension compared with factory plastic arms, and it is intended for routine replacement or incremental tuning on 1/10 scale TT-01 models.

The package includes the arm and associated hardware listed in the product title: shims, collars, E-clips, pins and screws, supplied for direct swap with the stock rear lower arm. No additional modifications to the chassis are described in the source, so fitment assumes standard TT-01 mounting points and hardware interfaces.

Installation notes: remove the rear suspension linkage and old arm, transfer any factory bearings or linkage pieces as required, and secure the alloy arm using the supplied pins and E-clips. This arm is primarily a chassis-level upgrade to alter rear geometry stability and component durability during normal RC driving and setup adjustments.
