NOTE: While you can use your vehicle’s stock ubolts with CalTracs, Calvert Racing’s 1/2″ diameter u-bolts is an upgrade as most stock applications come with 7/16″ diameter u-bolts. We recommend torqueing the u-bolts to 65-70 foot lbs. After running the vehicle down the track a few times, we also recommending checking the u-bolts and readjusting if necessary. Please see the FAQ page on this website or CalTracs Installation Guide for more info.
