SET OF TWO SPRING SLIDERS
Designed to fit Calvert Leafsprings installed on ALL CARS & TRUCKS (except Chevy Bel Air). Outside diameter aluminum bushings: 1″.
May also fit most Chrysler factory springs due to rear bearing size.
Heavy Duty roller bearings keep the leafspring and body from binding up during suspension movement. Replaces the existing shackles.
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.
