Product images may differ from actual product appearance.

Thumpr Camshafts are the hottest cams to hit the streets in more than a decade. Applying a design originally for endurance racing, they combine early exhaust valve opening, long exhaust duration, and generous intake/exhaust overlap. Best of all, Thumprs will not negatively impact power output or streetability.
