HPI Bullet Front Suspension Arm Set - Orange Alloy - BUL-18003-OR by Jazrider  [BUL-18003-OR]

Orange alloy front lower arms

This is an RC-scale front suspension arm set intended for HPI Bullet vehicles, supplied as model BUL-18003-OR. The set uses an orange anodised alloy finish to replace stock plastic arms where greater rigidity and wear resistance are desired without changing chassis geometry.

Compatibility follows the BULLET 3.0 MT and ST (Nitro Engines) family as indicated in the product name. Installation follows the usual front lower arm swap: remove the factory arms, transfer wheel hubs and hinge pins if needed, then fit the alloy arms to the existing mounting points using the stock hardware. Standard hobby hex drivers are normally all that is required.

From a tuning standpoint, replacing plastic with alloy reduces flex under load, which can sharpen steering response and improve stability at speed or with heavier tyres and firmer springs. After fitment, check shock tower alignment and hinge pin wear, and confirm suspension travel to ensure no binding occurs.
