From the first prototype camshaft belt drive ever manufactured by Dan Jesel back in 1982 to the sleekness of today's CNC machined pieces, Jesel Camshaft Belt Drives continue to lead the industry as the premiere camshaft belt drive assembly.
In the never ending quest for more horsepower, engine builders in the 1970's began using larger cam lobes which in turn required stiffer springs. The stiffer springs allowed the engine to turn more rpm, but eventually became too much for a timing chain to handle. At the time, gear drives were the only solution, but they bring with them their own set of problems. Gear drives transfer a tremendous amount of crankshaft harmonics to the valvetrain, not to mention taking incredible amounts of horsepower to drive.
As necessity is the birth of most components in high performance engines, the Jesel Camshaft Belt Drive was created to solve these problems.
Recognising the need for improvement, Dan Jesel did what he does best. Using internal cam belt assemblies as a blueprint, Dan engineered a system to externally adapt this technology to a small block Chevrolet. After sourcing a belt and gathering material, Dan went to work manufacturing the prototype pieces and in conjunction with a local engine builder successfully built and tested the drive on a NHRA Competition Eliminator engine. The results were more than impressive and the dyno numbers proved it.
To date, Jesel has engineered an arsenal of over 40 belt drive assemblies. So, whether you're on a six second pass down a quarter mile drag strip, racing in a 24 hour endurance race or just taking a trip down to the local car show, you can be assured that the components controlling your cam timing are of the highest standards and machined to exacting tolerances.
