- Jesel Precision Camshaft Belt Drive Kits - BBC
It's safe to say that JESEL is the originator of the modern racing belt drive system. Like most JESEL valvetrain components its belt drive was born out of necessity as NASCAR racers were experiencing frequent timing chain failures in 500-mile races. It has been refined over the years to a precise timing system that is durable enough to endure tough 24-hour races such as Daytona and Le Mans or a full-season of circle track competition. Racers have been rewarded with years of service from their JESEL belt drives by simply replacing the belt at recommended service intervals. Besides being more durable than gear or chain drives, JESEL's belt drive systems offer a number of advantages.
