These aluminium rear suspension arms are supplied as model JR-M705-BK and are designed for use with the Tamiya M-07 rear suspension. The item is a replacement/upgraded arm in black that interfaces with the factory rear mounting points on the M-07 chassis.
The arms function as tuning hardware: upgrading to aluminium can lower pivot deflection and deliver steadier handling during setup adjustments. Keep the original mounting locations and link geometry when fitting to maintain ride height and toe; always check clearance throughout suspension travel.
Installation tips: attach to the existing rear suspension pivots on the M-07 chassis, verify thread engagement and secure fasteners in line with the chassis supplier's recommended fitment. Re-check alignment and suspension movement after fitting and carry out a short test to confirm handling changes.
