U-Bolts, Round/set, 2.75″x9″ (UR275x90)
SET OF FOUR ROUND U-BOLTS w/hardware
2.75″ axle diameter x 9″ long, for axle ABOVE springs
Round U-bolts, zinc plated Grade 5 material, 1/2″ diameter, kits include 4 U-bolts, with nuts and washers.
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.
