HPI Bullet Black Alloy 14mm Wheel Hex by JAZRIDER BUL-18013-BK  [BUL-18013-BK]

14mm wheel hex for HPI Bullet

This JAZRIDER BUL-18013-BK is an RC-scale 14mm wheel hex intended for HPI Bullet spares, supplied as a black alloy replacement part. It is designed to interface with the BULLET 3.0 MT and BULLET 3.0 ST wheel hubs and serves as a direct-fit component for wheel mounting and routine parts replacement.

Use this wheel hex when replacing worn hexes or when swapping wheel types during setup changes. Installation normally involves removing the wheel and hub retaining hardware, seating the hex onto the hub splines, and reinstalling the wheel nut or lockring. Check hub alignment and thread engagement during assembly to maintain safe wheel retention on RC runs.

On tuning and setup, wheel hexes like this are used to ensure concentric wheel mounting and to avoid slop between hub and wheel, which helps keep handling consistent on track or off-road layouts. Maintain fastener torque and inspect for wear as part of regular RC maintenance schedules.
