Tamiya TT01/TT01E Aluminum Rear Lower Arms for Improved Stiffness - JR-TT107-BK by Jazrider  [JR-TT107-BK]

Stiffness and Handling Impact

This set of rear lower suspension arms fits the Tamiya TT01 and TT01E chassis and is supplied in black as model JR-TT107-BK. The parts are aluminum replacements for the standard plastic rear lower arms and are designed to bolt into the chassis' existing rear suspension points.

Installing aluminum lower arms will generally make the rear linkage more rigid, which can stabilise rear-end reactions and improve setup predictability. They affect pivot geometry and wheelbase alignment, so combine the upgrade with shock and toe adjustments for best handling results. These components are for model use only.

Installation notes: remove the original plastic arms and fit the aluminum replacements at the same mounting positions, using the chassis' existing screws and pins when appropriate. A hex driver and common hand tools are sufficient; after installation, check pivot play and linkage paths to confirm free movement.
