HPI Bullet Front Knuckle Arms Orange Alloy Upgrade - BUL-18000-OR by Jazrider  [BUL-18000-OR]

Front knuckle arms summary

This part is an orange alloy front knuckle arm set designed specifically for HPI Bullet vehicles. It replaces stock plastic steering knuckles to provide firmer mounting points, reducing flex under load and helping to maintain accurate steering geometry during demanding driving.

Design and role: the alloy construction emphasizes dimensional stability and wear resistance at the steering pivot and linkage contact areas. In use, these knuckles act as a tuning item to sharpen steering feel and to keep suspension geometry consistent when changing tyres, shocks, or camber settings.

Fitment and installation notes: this item is intended for BULLET 3.0 MT and ST models. Confirm existing hardware and bearing arrangements before fitting, transfer any sealed bearings as required, and verify alignment during reassembly. Replace worn fasteners and check for proper clearance through full suspension travel after installation.

Maintenance and service: inspect mating faces and ball-socket interfaces regularly for play or wear, keep pivot areas free of grit, and replace components damaged by impact to preserve predictable steering response. Use correct replacement fasteners and avoid over-tightening to prevent stress concentrations.
