The JAZRIDER HPI-86151 heavy duty dog bone is a direct replacement designed to toughen up the HPI Savage X drivetrain. Its 8x77mm form factor is chosen to match stock geometry while providing improved resistance to impact and fatigue.
Engineered for regular heavy use, this dog bone helps prevent common breakages during jumps and high-stress maneuvers. It offers a reliable option for hobbyists who alternate between club laps and rough bashing.
Made to fit the Savage X series, the part installs without extensive modification. Standard tools and a routine install procedure let you get back on the track quickly.
