Fabtech Round U-Bolt Kit - 1/2-20 x 8.70 x 2.75

These U-bolts measure 1/2-inch thread diameter with a 20-thread-per-inch pitch, and have a length of 8.70 inches with a 2.75-inch inner width. They are designed for the rear of your truck and offer a cost-effective solution for lifting the back end. This kit is a straightforward way to achieve a bit more height for your suspension setup.

When you're looking to raise the rear of your truck, a U-bolt kit like this one is a common and simple way to get it done. They secure the axle housing to the leaf springs, and by using longer U-bolts, you can accommodate additional lift blocks or modify the spring perch height. This particular kit from Fabtech is a well-built option that gets the job done without adding a lot of complexity or expense to your project.
