HPI Racing CVD Shaft Set for Bullet MT/ST – Optional Upgrade

Overview

The HPI Racing CVD Shaft Set is an optional drivetrain upgrade designed for the HPI Bullet MT and Bullet ST 1/10-scale vehicles. CVD (Constant Velocity Drive) shafts deliver smoother, more consistent power through the full range of suspension travel compared to standard dogbone-style shafts.
