Specifications:
Thumpr Camshafts are available in three different grind profiles, each one of which will produce a rough, racy exhaust note and impressive amounts of horsepower and torque at a different rpm range. Their cutting-edge hydraulic roller design means that they will deliver a substantial power increase over an identical hydraulic flat tappet grind without sacrificing reliability or ease of maintenance. So look no further than the Thumpr line of camshafts - engineered to deliver that much sought-after ''thumping'' idle quality to everyone.
