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

Overview of rear hub carrier fitment

This RC-scale rear hub carrier is designed for the HPI Bullet series and is referenced by model BUL-18009-GU. Constructed in gunmetal alloy, it is offered as a replacement or upgrade for the rear carriers used on BULLET 3.0 MT and ST nitro models.

The carrier's function is to retain the wheel hex and assembly while channeling suspension forces into the rear upright and axle. In use it affects rear suspension stiffness, wheel runout repeatability, and overall durability when running off-road with nitro power. Use it as a chassis tuning element when refining toe, camber stability, or rear compliance.

Typical installation: remove the old carriers from the hub/knuckle, mount the replacement using the original mounting points and fasteners, and validate wheel hex alignment and bearing seating before fully tightening. Verify that the part is compatible with your BULLET 3.0 MT or ST model prior to fitting.

Upkeep recommendations: check mating surfaces and fasteners after initial track sessions and re-torque after the thermal cycles associated with nitro operation. Proper ball bearing selection and firm hex retention will help maintain alignment and reduce wear over time.
