Dan Jesel invented the Small Block Chevrolet Belt Drive back in 1982 with one goal in mind, to make the most accurate and durable cam timing system available. And in its 29 years of existence, our Belt Drives have often been duplicated, but never matched. Whether you’re running a 24 hour endurance race or a 5 second pass down the drag strip, you can count on JESEL to get you to the finish line first. Our drives reduce the amount of harmonics being transferred to the camshaft and have been proven over the years to outlast chain drives. Introduced in 2009 and available for our more popular drives, JESEL has introduced a cost effective, solid upper pulley design drive. This new drive shares all of the components from our standard drive with the exception of the upper pulley. Cam timing is adjustable externally ± 8° in 2° increments.
Patented High Torq Drive™ reinforced belt operates dry and spins with less friction than timing chains or gear drives and also absorbs harmonics.
Hardware is Grade 8 Allen and Torx™ head design.
Crank Pulley is heat-treated steel and incorporates a High Torq Drive™ tooth configuration.
Teflon® coated high vacuum cam and crank seals.
Cam timing adjustment is made externally providing the easiest and most accurate tuning available.
Hard coated Billet Aluminum Upper Pulley features patented High Torq Drive™ tooth configuration.
Accessories available to run distributor drives, fuel pumps or oil pumps off front of cam.
Cam timing is externally adjustable.
2 Piece Upper Pulley Design is infinitely adjustable ±10°.
For those racers who run both Camshaft Belt Drives along with the JESEL Front Mount Distributor, JESEL offers a Front Drive Kit that incorporates the two units into one convenient part number. This value packed combination is available for our most popular applications and requires the use of a crank trigger style ignition system.

JESEL's Belt Driven Distributor eliminates timing inaccuracies due to camshaft deflection and cam walk. A typical distributor driven by the cam gear has a history or retarding the timing at high RPM due to camshaft twisting from torsion loads. When used in conjunction with a crank trigger and external ignition box this drive provides the engine builder with an accurate ignition system that will not deviate from the initial setting.
Designed to handle the high cylinder pressures experienced in Pro Stock and Pro-Mod type engines, this distributor drive features the MSD® 5” Pro-Cap to ensure accurate spark delivery and to reduce spark scatter frequently experienced in high cylinder pressure applications. This drive is available for all popular applications and can be ordered with the optional Individual Cylinder Timing setup for use with electronic fuel injection systems.
