HPI Bullet Front Steering Knuckle Arms (Orange Alloy) for BULLET 3.0 MT & ST - BUL-18000-OR by Jazrider  [BUL-18000-OR]

Knuckle arm function and fit

This set of orange alloy front knuckle arms upgrades HPI Bullet steering components to reduce mating-surface flex and preserve accurate steering geometry under load. They are intended as an aftermarket upgrade to improve repeatability compared with standard plastic knuckles.

Design and role: manufactured alloy parts concentrate on bore precision and resistance to wear at the steering pivot and linkage seating areas. As a tuning element, the knuckles help retain consistent suspension geometry when altering tyre choice or shock valving.

Fitment and installation notes: compatible with BULLET 3.0 MT and ST chassis. Verify bearing size and existing hardware before fitting, transfer sealed bearings as necessary, and set alignment carefully during reassembly. Confirm full suspension travel to ensure no part-to-part interference.

Maintenance and service: periodically check pivot and ball-socket areas for play, keep joints clear of abrasive debris, and replace any items that show impact damage to keep steering predictable. Use proper fasteners and avoid excessive torque to reduce stress concentrations at holes and shoulders.
