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

Rear suspension arm for HPI Bullet

This is an RC-scale rear suspension arm intended for HPI Bullet series models, offered as a black alloy replacement part for the rear suspension assembly. It is supplied for use with the specified HPI Bullet platforms and is described as a direct rear arm option for compatible Bullet 3.0 MT and ST models with Nitro engines.

In practical terms the part is positioned as a chassis-level replacement that restores rear suspension geometry and provides the different stiffness and wear characteristics of an alloy component versus typical stock materials. Installers should treat it as a like-for-like swap at the rear mounting points, checking hinge pin alignment and linkage clearances during fitment. Basic steps include removing the wheel and body where required, separating the rear arm from the hub and chassis mounts, transferring any required bearings or hardware, and reassembling while verifying travel and binding.

Tuning role: fitting an alloy rear arm changes the mechanical feel at the rear end, which can affect responsiveness, consistency under load, and how the chassis reacts to suspension setup changes. Use it as part of a measured setup change when adjusting spring rates, shock positions, or toe/camber settings to assess handling differences on your chosen track surface.
