Front Drive Combos

For the engine builder planning on using a Camshaft Belt Drive as well as a Belt Driven Distributor, Jesel offers a Front Drive Combo which incorporates both units as one convenient part number. In addition to being an ordering convenience, the Front Drive Combo is easier on your budget as the units are discounted when bundled together. The combo can be ordered with either our Pro Series or Extreme Series distributors with or without the available Individual Cylinder Timing system. As with all Jesel distributor drive systems, a crank trigger type firing system as well as an external ignition box is required.

Distributor Drives

Jesel’s Belt Driven Distributor systems, a direct bolt-on accessory to our Camshaft Belt Drives, eliminates timing inaccuracies due to camshaft deflection and cam walk. A typical gear driven distributor running off the camshaft has the possibility of altering the initial ignition setting at high RPM due to the camshaft twisting from torsional loads. By driving the distributor drive directly off the camshaft pulley, ignition timing stays constant and will not deviate from the initial settings. Another benefit to using our Belt Driven Distributors is the ability to set the engine back further in the chassis without worrying about firewall or windshield interference. A crank trigger firing system along with an external ignition box is required for all Belt Driven Distributor systems.

Extreme Series Distributor Drive

Introduced in 2011, Jesel’s Extreme Series Distributor Drive System is 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.

Jesel Pro Series Distributor Drive.png

Pro Series Distributor Drive

Ideal for naturally aspirated engines, this drive features a Gates PowerGrip HTD belt and uses Moroso® Ultra Series distributor components. The balanced brass rotor tip and form staked carbon ball on the coil lug have been designed to eliminate grounding paths and cross firing. 

Jesel Individual Cylinder Timing Drive.png

Individual Cylinder Timing Drive

Available in either series, Jesel’s ICT timing systems provide a simple and accurate cam sync source for engines operating with an electronic fuel injection system. This drive is setup to use a 3/8-24 non-magnetic pickup (not supplied) which picks up the cam position off a rare earth magnet embedded in the external rotor. The pickup can be indexed every 60° for ideal wire routing.

Belt Drive Accessories
