HPI Bullet Rear Suspension Arm Alloy Upgrade - BUL-18010-BK by JAZRIDER  [BUL-18010-BK]

Aftermarket alloy rear arm for HPI Bullet

This is an aftermarket black alloy rear suspension arm designed to replace the stock rear arm on HPI Bullet vehicles. It is supplied for fitment on the Bullet 3.0 MT and ST platform variants running nitro engines.

The part functions as a direct rear arm replacement that preserves suspension geometry while introducing the material characteristics of an alloy component versus common stock materials. Installers should perform a like-for-like swap at the mounting points, ensuring hinge pins, bearings, and linkage clearances are correct. Usual fitment steps include removing relevant bodywork and wheels, separating the arm from hub and chassis mounts, transferring bearings and hardware, and reassembling while verifying travel and binding.

Performance note: an alloy arm changes the rear mechanical feel and can influence consistency and response under load. Introduce it as a controlled change when tuning springs, shocks, or alignment to evaluate its handling effects.
