RC rear arm — Bullet fit overview

This alloy rear suspension arm is a scale replacement tailored to the HPI Bullet chassis and identified as model BUL-18010-GU. It acts as a direct-fit rear lower arm that can replace broken plastic parts or serve as a simple upgrade where increased stiffness and wear resistance help tuning consistency.

The arm's material and geometry are designed to retain stock mounting points and suspension geometry so wheel alignment and kinematics are preserved. Installation needs standard RC hand tools; confirm pivot-pin fit, properly seat ball cups, and verify the arm clears shocks and linkages throughout travel. No other driveline adjustments are required for fitment.

Fit this arm to refresh handling predictability on BULLET 3.0 MT and ST models or when setting up the vehicle for tuning sessions at the track or in practice runs.

How will this arm change handling?

The alloy arm increases stiffness in the rear suspension which can sharpen steering response and reduce flex, helping consistent setups during tuning.

Should I adjust shocks after installing?

It is a good idea to recheck preload and damping since the stiffer arm may alter roll characteristics; small shock adjustments can restore the desired balance.

Does weight of the arm affect performance?

The metal arm is heavier than plastic, which can lower the rear center of gravity slightly and influence traction; factor this in when fine tuning suspension settings.
