HPI Bullet MT Front/Rear Universal Drive Shaft, Black Steel - BUL-18012-BK by Jazrider  [BUL-18012-BK]

Front and rear universal shafts engineered for Bullet MT

This is an RC-scale replacement drive shaft set specified for HPI Bullet MT models, supplied as a 2-piece kit with model code BUL-18012-BK. The components are made from black steel to act as direct front and rear universal shaft replacements for the Bullet MT chassis, intended for routine maintenance and drivetrain reinforcement in off-road RC applications.

The shafts are designed to replace worn stock units; installation involves removing the existing universal shafts, seating the new shafts into the same coupling points, and tightening the retaining hardware while maintaining correct alignment. Inspect hex adapters and wheel hub mating faces before fitting to ensure proper engagement and to avoid binding.

From a setup perspective, swapping in black steel drive shafts restores drivetrain integrity after wear and provides a stable platform for further drivetrain upgrades. After fitting, confirm free rotation through suspension travel and check that joint play remains within acceptable limits.
