If you are looking to gain more clearance on the trail, this u-bolt flip kit is just what you need. This kit includes 4 heavy duty 5/8" diameter u-bolts and 2 heavy duty 3/8" thick u-bolt plates. The u-bolts accommodate a 3" diameter axle tube. This kit is designed to work with 2-1/2" wide springs. All of the components in this kit are manufactured in the U.S.A. and we recommend they be painted or powder coated during installation, as they're shipped without finish.
