Overview
The HPI Racing 20T (1M) Racing Clutch Bell is a hardened-steel drivetrain upgrade engineered for HPI Savage monster trucks. Precision-machined for strength and balance, it delivers reliable, repeatable performance under aggressive nitro power and demanding bashing conditions.
Strategically machined cooling and lightening holes reduce rotating mass for sharper throttle response while improving airflow to the clutch shoes – helping maintain consistent engagement and clutch temperatures during extended runs.
