Tamiya TA07 & TB04 Pro II Aluminum Rear Arms Upgrade JR-TA707-GU by Jazrider  [JR-TA707-GU]

Rear Arm Upgrade for Touring Chassis

This aluminum rear suspension arm kit fits Tamiya TA07 and TB04 Pro II chassis as a direct replacement, finished in a subdued gun metal tone to reduce visual contrast while strengthening the rear mounting points for 1/10-scale touring cars.

Aluminum construction shifts flex behavior versus the stock plastic parts, helping keep suspension geometry more consistent when subjected to cornering loads. Drivers use these arms when dialing in rear roll stiffness and camber control as part of suspension setup changes.

Fitment tips: install the arms into the stock rear pick points and verify clearance around the motor and gearbox. Keep original ball studs if they match thread and wear specs; torque and recheck fasteners after a short run to confirm everything remains secure.
