HPI Bullet Compatible Rear Arm Upgrade for BULLET 3.0 MT and ST - Black Alloy BUL-18010-BK by JAZRIDER  [BUL-18010-BK]

Heavy-duty rear arm for HPI Bullet

This item is an alloy rear suspension arm intended for HPI Bullet models, supplied as a black replacement for the rear suspension assembly. It is specified for use with Bullet 3.0 MT and ST platforms equipped with nitro engines.

Functionally the part serves as a direct chassis-level replacement that reinstates rear suspension geometry while offering the typical stiffness and wear advantages of an alloy component over standard stock parts. Fitters should approach it as a like-for-like swap at the rear mount points and confirm hinge pin alignment and linkage freeplay throughout the process. Standard installation involves wheel and body removal as needed, detaching the arm from hub and chassis mounts, moving bearings and hardware across, and reassembling while checking travel limits and binding.

Durability focus: alloy construction gives improved resistance to wear and impact compared with softer stock materials, which can reduce replacement frequency. Use the arm as part of planned maintenance or reinforcement when operating on rough surfaces or under heavier loads.
