HPI Bullet Rear Hub Carrier - BUL-18009-GU for BULLET 3.0 MT/ST by Jazrider  [BUL-18009-GU]

Rear hub carrier details

This is an RC-scale rear hub carrier intended for the HPI Bullet platform and listed as model BUL-18009-GU. The part is made from gunmetal alloy and is offered as a replacement or upgrade for the rear hub carriers on BULLET 3.0 MT and ST nitro models.

It locates the wheel hex and assembly while transferring suspension forces into the rear upright and axle area. In practical terms the carrier affects rear suspension stiffness, wheel runout consistency, and durability under off-road nitro use. Treat it as a chassis tuning component when adjusting toe, camber retention, or rear compliance.

Installation: remove the existing rear carriers from the hub/knuckle assembly, install the replacement using the original mounting points and fasteners, and confirm wheel hex alignment and bearing seating before final tightening. Verify compatibility with BULLET 3.0 MT and ST models and confirm bearings and hexes fit correctly.

Maintenance: inspect mating surfaces and fasteners after initial runs, and re-torque hardware after heat cycles typical of nitro operation. Correct ball bearing selection and secure hex mounting will preserve alignment and reduce wear.
