HPI Bullet Rear Lower Suspension Arm BUL-18010-GU for BULLET 3.0 MT/ST by Jazrider  [BUL-18010-GU]

Rear lower arm for HPI Bullet

This alloy rear suspension arm is an RC-scale replacement part designed for the HPI Bullet chassis, supplied as model BUL-18010-GU. The component is a direct-fit rear lower arm intended to replace damaged plastic arms or to provide a modest upgrade that increases stiffness and wear resistance in the rear suspension assembly.

The alloy material and formed profile maintain the stock geometry and mounting points to preserve wheel alignment and suspension kinematics. Installation is straightforward with standard RC tools: verify pivot-pin clearance, confirm ball cup seating, and ensure the arm clears shocks and linkages through full travel. No changes to other driveline components are required.

Choose this arm when replacing worn rear lower arms on BULLET 3.0 MT and ST chassis to restore predictable handling or to prepare the model for regular track maintenance and tuning sessions.
