Dan Jesel invented the Small Block Chevrolet Camshaft Belt Drive back in 1982 with one goal in mind – to make the most accurate and durable cam timing system available. Since then Jesel Camshaft Belt Drive Systems have often been copied, but have never been duplicated. Today, we offer systems for over 45 unique applications, so whether you’re running a 24 hour endurance race or a 4 second pass down the drag strip, you can count on Jesel to get you to the finish line first.
Built with the finest materials available, our Camshaft Belt Drives feature several performance and valve train stability enhancements over traditional timing chains and gear drives. The Gates patented High Torq Drive™ reinforced belt spins dry on a steel crank pulley and a hard coated aluminum upper pulley and helps isolate crankshaft harmonics to the valve train. Teflon® coated high vacuum cam and crank seals are long lasting and insure the extreme amount of vacuum found in today’s race engines stays sealed in the crankcase. Cam timing can be externally adjustable ±10° in minutes to dial in the power curve and cam thrust can be reduced to as little as .001” with our available dual thrust cam adapter assemblies.
Another advantage to running our Camshaft Belt Drive is the ability to swap out cams directly through the front cover. Cam swaps can be performed quickly without needing to remove the oil pan by simply removing the upper cam pulley and un-bolting cam seal plate saving countless hours during dyno sessions.
With over 42 applications from OEM blocks to aftermarket raised cam blocks, you can be certain that the Camshaft Belt Drive used to win countless championships will provide you with years of durable race winning service.
