This kit will allow more ground clearance under the springs, upgrade the strength of your bolts to 5/8" and look good doing it. We use 3/8" laser cut zinc-plated material for the plates too. There is enough thread on the ubolts  to handle a stock width spring or up to 2" lift blocks on a 4wd. If you have more than a 2" lift block please contact us as we can provide you with longer U-bolts if needed. Note; the factory bumpstop typically gets removed with this kit. You can easily spot weld the bump to the springplate if desired.
