This aluminium rear lower suspension arm set fits the Tamiya TT01 and TT01E chassis and is supplied in black under model JR-TT107-BK. The parts are designed to replace the stock plastic lower arms and mount to the same rear suspension points on the chassis.
Use the upgrade to gain a firmer rear link that helps stabilise rear-end responses during setup changes. The arms influence pivot geometry and wheelbase alignment, so pair them with shock and toe tuning to achieve the best handling balance. These components are intended for RC use only.
Installation notes: remove the stock rear lower arms and install the aluminium units at the original mounting locations, reusing compatible screws and pins where suitable. Basic hand tools and a hex driver are enough for the job; after fitting, confirm free pivot movement and correct linkage routing.
