CalTracs HD Truck - Standard 80-91 Ford F150 2wd with 2.5in springs flipped

The Calvert Racing CalTracs (MPN 7631) are a bolt-on traction system designed for trucks with 2.5" wide leaf springs, featuring full pre-load adjustability. This system keeps the axle from rotating, maintains pinion angle, and eliminates spring wrap-up, leading to improved 60-foot times and reduced wheel hop. Constructed with Chromoly preload links and HD Rod Ends with over 14,000 pounds radial static load capacity, and 5/16" mild steel rear mounts, these black powder-coated CalTracs offer unsurpassed quality and craftsmanship. Berlin-style pivot plates are included for most applications, and a full-color installation guide is provided.
