For HPI Bullet: Gunmetal Rear Suspension Arm BUL-18010-GU upgrade for BULLET 3.0 MT and ST by Jazrider  [BUL-18010-GU]

Hardened alloy replacement arm for Bullet

This alloy rear suspension arm is an RC-scale replacement crafted for the HPI Bullet chassis and listed under model BUL-18010-GU. It functions as a direct-fit rear lower arm suitable for swapping out damaged plastic parts or as a light upgrade where greater stiffness and reduced wear are beneficial.

The chosen alloy and arm profile aim to preserve the original mounting geometry so wheel alignment and suspension kinematics remain consistent. Basic RC tools are sufficient for installation; check pivot-pin alignment, ball cup seating, and ensure the arm clears shock absorbers and linkages across the full range of travel. No driveline modifications are implied.

Use this arm to restore handling consistency on BULLET 3.0 MT and ST models or when preparing the vehicle for regular maintenance and setup sessions on track or trail.
