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

Replacement rear hub carriers for Bullet

This part is an RC-scale rear hub carrier intended for the HPI Bullet platform and carries the model number BUL-18009-GU. The item is specified in gunmetal alloy and serves as a direct replacement or upgrade for rear hub carriers on BULLET 3.0 MT and ST nitro models.

Its primary role is to locate the wheel hex and wheel assembly while transferring suspension loads into the rear upright and axle area. Practically, that affects rear suspension stiffness, wheel runout consistency, and the component's service life under off-road nitro conditions. Consider it when making chassis-level tuning adjustments that influence toe, camber retention, or rear compliance.

Installation is typical: remove the existing rear carriers from the hub/knuckle assembly, fit the new carriers using the original mounting points and hardware, then confirm wheel hex alignment and bearing seating before final torque. Ensure compatibility with BULLET 3.0 MT and ST prior to installation.

Maintenance guidance: inspect mating surfaces and fasteners after initial runs and re-torque hardware following the heat cycles common to nitro operation. Fit correct ball bearings and confirm secure hex mounting to keep alignment and reduce wear.
