HPI Bullet Orange Alloy Front Arms - BUL-18003-OR by Jazrider  [BUL-18003-OR]

Orange alloy front arms overview

This is an RC front suspension arm set designed for HPI Bullet models and identified as BUL-18003-OR. The orange anodised alloy construction is intended to replace stock plastic arms to increase rigidity and improve wear characteristics while maintaining correct geometry.

Compatibility targets the BULLET 3.0 MT and ST (Nitro Engines) series stated in the product title. Standard installation consists of removing the original arms, transferring hubs and pivot pins where necessary, and fitting the alloy arms into the factory mounting points using existing hardware. No special tooling beyond hobby hex drivers is normally required.

As a tuning component, alloy arms lower elastic flex under load, offering firmer steering feel and improved response, especially with stiffer springs or larger tyres. After fitting, check hinge pin condition, shock tower alignment, and full suspension movement to ensure no binding occurs.
