Upgrade details: front arms in orange alloy

This RC front suspension arm set fits HPI Bullet vehicles and carries the model code BUL-18003-OR. The orange anodised alloy replaces the factory plastic arms to provide increased rigidity and improved wear characteristics while preserving the vehicle's intended geometry.

The product lists compatibility with the BULLET 3.0 MT and ST (Nitro Engines) family as shown in the title. Installation is the standard procedure: remove the stock lower arms, move over hubs and pins as required, and secure the alloy arms to the factory attachment points using the existing hardware. Basic hex drivers are usually sufficient for the job.

From a tuning perspective, alloy lower arms reduce chassis flex at the front end, producing a crisper steering feel and enhanced response under load. After fitting, verify hinge pin condition and shock tower geometry, and check suspension travel to ensure proper clearance throughout the range.

Stiffer arms reduce chassis compliance, delivering more immediate steering input; you may need to soften other suspension elements to retain desired balance.
It is common to retune spring rates or damping to suit the reduced arm flex—start with small adjustments and test progressively.
Confirm there is no binding through full suspension travel, recheck hinge pins and fastener torque, and ensure steering link geometry remains correct.
