IFS Pickup Chevy, GMC Block & U-Bolt Kits
To compensate for loss of rear leaf spring height, a new rear block and u-bolt kit is sometimes all you need. This option doesn't affect ride quality and can get your Chevy or GMC truck back to either its original or more level stance. Contact us to learn more about these GMC truck leaf spring lift kits.
The Superlift rear block kits include a pair of cast iron blocks along with u-bolts, locking nuts and washers.
