Overview
The HPI Racing 15T (1M) Racing Clutch Bell is a heavy-duty drivetrain upgrade for HPI Savage monster trucks where immediate throttle response, torque, and control are top priorities. Machined from hardened steel, it's engineered to withstand extreme nitro power and aggressive driving conditions while delivering consistent, repeatable performance.
Lightening and cooling holes reduce rotating mass and improve airflow to the clutch shoes, helping maintain consistent engagement during prolonged hard-running sessions.
