HPI Bullet MT Front/Rear Universal Shafts Black Steel BUL-18012-BK (compatible with Bullet MT) by Jazrider  [BUL-18012-BK]

Universal drive shafts for HPI Bullet MT compatibility

This is a replacement drive shaft set specified for HPI Bullet MT models, supplied as a 2-piece kit identified by model BUL-18012-BK. The parts are produced in black steel to serve as direct replacements for the front and rear universal shafts on the Bullet MT chassis, intended for maintenance and reinforcement in off-road RC use.

Installation calls for removal of the current universal shafts, seating the new shafts into the same coupling locations, and securing the retaining hardware while keeping correct alignment. Check adjacent components, such as hex adapters and wheel hub mating faces, before fitting to ensure proper engagement and to avoid binding.

When planning upgrades, replacing worn drive components with black steel shafts is a practical way to restore drivetrain integrity and provide a consistent interface for further drivetrain improvements. After fitting, verify free rotation through the full range of suspension travel and ensure there is no excessive play at joint connections.
