Tamiya TT01/TT01E Aluminum Rear Lower Suspension Arms by JAZRIDER JR-TT107-BK  [JR-TT107-BK]

Rear Lower Suspension Arms

This is an RC-scale rear lower suspension arm set for the Tamiya TT01 and TT01E chassis, supplied in black and produced by JAZRIDER under model JR-TT107-BK. The component is an aluminum replacement for the stock plastic rear lower arms and is intended to serve as a direct-fit option that interacts with the existing rear suspension mounting points on the chassis.

Use this part when you want a more rigid rear lower arm for tuning rear-end feel and consistency. When fitted, the arms act on wheelbase alignment and pivot geometry, so they are typically used alongside shock and toe adjustments to refine handling. The parts work as RC-scale suspension hardware only and are not for real vehicle use.

Installation notes: remove the original rear lower arms and fit the aluminum units to the same mounting locations, using the existing screws and hardware from the chassis where applicable. Basic hand tools and a hex driver are sufficient for installation; check pivot pin play and linkage routing after fitting to confirm free movement of the suspension.
