HPI Bullet MT Black Steel Front/Rear Driveshafts BUL-18012-BK - Upgrade for Bullet MT by Jazrider  [BUL-18012-BK]

Front and rear driveshaft replacements for Bullet MT

This RC-scale replacement drive shaft kit fits HPI Bullet MT models and is supplied as a 2-piece set marked BUL-18012-BK. The shafts are manufactured in black steel to act as direct front and rear universal shaft replacements for the Bullet MT chassis, intended for maintenance and drivetrain reinforcement in off-road use.

To install, remove the worn universal shafts, insert the new shafts into the original coupling locations, and tighten the retaining hardware while keeping correct alignment. Inspect hex adapters and hub mating faces before fitting to ensure proper engagement and to avoid binding during operation.

In terms of setup, swapping to black steel components is an effective way to restore drivetrain stiffness after wear and to create a reliable foundation for other drivetrain upgrades. After installation, check free rotation through full suspension travel and confirm joints show no excessive play.
