GPM Associated RC18T Rear Lower Arm Alloy 1pr with Pins AR056 Pack  [AR056]

Aluminium rear lower arm for RC18T tuning

This aftermarket alloy rear lower arm is manufactured as a direct-fit upgrade for the Associated RC18T platform and is supplied as a 1pr set complete with matching pins and screws. It uses the same mounting points and hardware format as the stock arm for straightforward replacement.

Designed for maintenance and setup work, the aluminium arm gives a firmer suspension pivot compared with typical plastic arms and can influence suspension geometry and handling when combined with shock or tyre changes. Fitment follows the stock arm removal steps and uses the supplied pins and screws to secure the arm to the hub and chassis mount.

Treat this component as a chassis spare for repair or when testing different setups; always check fitment on your RC18T machine before sustained running and restore original alignment settings unless you intend to change toe or camber deliberately.
