Precision alloy rear lower arm for RC18T applications

This aftermarket alloy rear lower arm is produced for the Associated RC18T chassis and supplied as a one pair set with matching pins and screws. It is engineered to the stock mounting geometry to provide direct replacement fitment while offering reduced flex compared with typical plastic parts.

The stiffer aluminium construction alters pivot stiffness and can influence suspension kinematics when paired with damper or tyre changes. Installation follows the OEM arm removal sequence and uses the supplied pins and screws to secure the arm to both hub and chassis mounts.

Consider this component as a durable spare for repairs or a controlled variable when testing setup adjustments; verify fitment on your RC18T before extended running and retain original alignment unless deliberately modifying toe or camber settings.

What are the key fitment checks before installation?

Confirm the rear hub and chassis mount spacing match the arm mounting holes and inspect supplied pins and screws for correct length and thread engagement prior to final assembly.

Will the alloy arm require different maintenance?

Periodic inspection of fasteners and pivot points is recommended; aluminium transfers load differently so check adjacent components for any accelerated wear after initial runs.

Is any setup tuning suggested after fitting?

Small adjustments to damping or sway settings may be needed to rebalance handling since the arm increases rear pivot stiffness; document baseline settings before changing them so you can revert if required.
