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

Rear hub carriers for Bullet chassis

This is an RC-scale rear hub carrier designed for the HPI Bullet platform, supplied by JAZRIDER under model BUL-18009-GU. The part is described as gunmetal alloy, intended as a direct replacement or upgrade for the rear hub carriers on BULLET 3.0 MT and ST (Nitro Engines) models.

Functionally the component locates the wheel hex and wheel assembly while transferring suspension forces into the rear upright and axle area. In practical terms it affects 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 rear-end compliance.

Installation is typical 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 full tightening. Verify compatibility specifically with BULLET 3.0 MT and ST (Nitro Engines) and confirm existing wheel hexes and bearings seat correctly.

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