Extra bhp, torque and driveability – that’s the Cat Cams performance difference! Whether it’s fast road, rally, rallycross, circuit or drag racing, if you’re looking for improved engine performance then Cat Cams has plenty to offer.

Computer simulation and CNC manufacturing techniques allow Cat Cams to pursue a unique design philosophy based on shorter durations and higher valve lifts. Compared to competitors this means Cat’s profiles offer better cylinder filling at lower engine speeds, producing higher levels of torque and tractability allied to improved top end power.

Unlike its competitors Cat Cams only grinds ‘new’ cams, either from chilled castings or virgin steel billets. So if it’s street, strip or stage rest assured you’re getting a performance cam quite unlike any other, proven by Cat Cam’s successes in the European Touring Cars (including BTCC class winners), the Le Mans 24 hours and Moto GP.
