The Calvert Racing 6520 CalTracs Traction Bar Kit is a bolt-on leaf spring traction system specifically engineered for 1966-1967 Ford Fairlane and 1968-1971 Ford Torino and Grand Torino models. CalTracs keeps the rear axle from rotating under hard acceleration, maintaining correct pinion angle and eliminating spring wrap-up for consistent tire hook and improved 60-foot times. The 6520 kit includes low-profile 1-hole pivot plates that provide approximately 1.5 in. more ground clearance than the standard drag profile plates — ideal for daily driven street cars. The chromoly preload link provides maximum leverage with minimal flex, and 3/4 in. rod ends with grease zerks handle radial static loads of over 14,000 lbs. while reducing chatter. The two-piece aluminum front spring eye bushing assembly keeps the front pivot squared and rigid. Installation requires no cutting, welding, or modifications to factory suspension — uses your existing leaf springs and U-bolts. U-bolts are sold separately.
