Tamiya Compatible TA07/TB04 Pro II Rear Aluminum Arms - JR-TA707-BK by Jazrider  [JR-TA707-BK]

Precision Rear Lower Arms for TA07/TB04 Pro II

These aluminium rear suspension arms are produced as a direct-fit replacement for the Tamiya TA07 and TB04 Pro II touring car chassis. The machined aluminium construction increases rigidity versus stock plastic parts, and the black finish provides a discrete visual match to many touring car setups.

As the linkage between rear uprights and the bulkhead, the arms influence rear roll centre and toe geometry. When fitting the JR-TA707-BK units, check hinge-pin alignment and ball stud positions to preserve the intended kinematics. Minor adjustments to toe and camber will help dial in handling after installation.

Install using normal touring-car servicing steps: remove rear uprights, swap in the aluminium arms, and secure pins or set screws. Because aluminium shifts stiffness at the mounting points, re-evaluate shock settings and preload during a test run to ensure consistent behaviour.
