This steel main drive shaft is supplied as a 1 pr set for HPI Savage platforms, intended for service, repair and durability-focused rebuilds. It functions as the rotating linkage between gearbox output and axle assembly and is suitable for hobbyist installation and workshop replacement procedures.
The shaft material is steel and the model designation indicates fitment for HPI Savage, Savage X and Savage Fluorescent. It is intended as a direct replacement to restore worn shafts or to exchange fatigued original parts during maintenance cycles.
Installation guidance: remove the transmission output coupling and associated axle connections, confirm spline engagement and alignment, torque retaining hardware to recommended values, and verify free rotation before final assembly. During setup and tuning, inspect driveline angle and bearing condition to reduce binding and vibration and to maintain service life.
Use this steel main drive shaft when replacing worn drivetrain components on HPI Savage variants, focusing on accurate fitment and correct alignment to uphold drivetrain reliability.
