HPI Bullet front suspension arm set by JAZRIDER BUL-18003-OR  [BUL-18003-OR]

Front suspension arm, orange alloy

This is an RC-scale front suspension arm set intended for HPI Bullet vehicles, supplied by JAZRIDER under 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 is typical for front lower arms on the Bullet series: remove the original arms, transfer wheel hubs and pins where required, then fit the alloy arms using the existing mounting points and hardware. No additional tools beyond standard hobby hex drivers are normally required.

From a tuning perspective, alloy arms like these reduce flex under load, which can tighten steering feel and improve response on high-speed sections or when using stiffer springs and heavier tyres. Pay attention to shock tower alignment and hinge pin wear when swapping materials, and inspect for any fitment changes that could affect suspension travel.
