    CalTracs Diesel Traction Bars

    CalTracs, engineered by Calvert Racing, is the traction bar system built to stop wheel hop and put leaf-spring power to the ground on launch. Calvert Racing has been refining leaf-spring traction geometry since 1991, and that racing pedigree carries straight into the diesel truck lineup for Cummins, Powerstroke, and Duramax platforms. CFM Diesel Performance carries CalTracs kits for drivers who tow hard, launch harder, and refuse to leave traction on the table.

    Why Diesel Racers Trust CalTracs

    CalTracs is built by Calvert Racing, a company that has specialized in leaf-spring traction systems since 1991 out of Lancaster, California, with a catalog spanning bracket drag cars to modern diesel trucks.

    The design pairs an adjustable traction bar with a shock to control axle wrap and squat without the maintenance of a full traction-bar swap, and Calvert Racing dyno-tests every shock and verifies leaf-spring arch specs before it ships.

    CFM Diesel Performance stocks a growing selection of CalTracs kits for Cummins, Powerstroke, and Duramax trucks — traction bars, shocks, and related hardware below. Missing the exact kit for your application? Contact our team and we'll track it down.
