HPI Bullet Front Knuckle Arm Set Orange Alloy - BUL-18000-OR by Jazrider  [BUL-18000-OR]

Upgrade overview for Bullet knuckles

This orange alloy front knuckle arm set is an aftermarket upgrade for HPI Bullet vehicles, replacing standard plastic knuckles to reduce flex at steering pivots and help keep geometry stable under load. The parts aim to deliver more consistent steering feel during demanding driving conditions.

Design and role: the alloy parts prioritise accurate bore alignment and wear resistance at linkage and pivot locations. They serve as a tuning item to firm steering inputs and support repeatable suspension geometry when swapping tyres or changing shock settings.

Fitment and installation notes: listed for BULLET 3.0 MT and ST chassis. Confirm bearing types and hardware compatibility before installation, transfer sealed bearings if appropriate, and confirm alignment when reassembling. Check clearances through the full suspension travel after fitting to prevent interference.

Maintenance and service: inspect mating surfaces and ball-socket joints periodically for play or wear, keep pivot areas clean, and replace any components damaged by impact to preserve steering predictability. Use correct replacement fasteners and avoid over-tightening to minimise stress concentrations.
