HPI Bullet Rear Hub Carriers Gunmetal Alloy BUL-18009-GU by Jazrider  [BUL-18009-GU]

HPI Bullet rear hub carriers overview

This rear hub carrier is an RC-scale replacement designed for the HPI Bullet platform and identified as model BUL-18009-GU. It is manufactured in gunmetal alloy and serves as a direct replacement or performance upgrade for BULLET 3.0 MT and ST nitro models.

The component locates the wheel hex and wheel assembly while transferring suspension loads into the rear upright and axle area. In practical use it influences rear suspension stiffness, wheel runout consistency, and durability under off-road nitro running conditions. Treat it as a chassis-level tuning item when you adjust toe, camber stability, or overall rear compliance.

Installation follows the usual procedure for this class of part: remove the existing rear carriers from the hub/knuckle assembly, fit the replacement using the original mounting points and fasteners, and verify wheel hex alignment and bearing fit before final tightening. Confirm compatibility specifically with BULLET 3.0 MT and ST (Nitro Engines) and ensure your wheel hexes and bearings seat correctly.

Maintenance notes: inspect mating surfaces and fasteners after initial runs, and re-torque hardware after the heat cycles common to nitro operation. Using compatible ball bearings and secure hex mounting will preserve alignment and reduce premature wear.
