Product did not come with any instructions. My mechanic, who is ASE Certified and has been doing all sorts of lift kits had nothing nice to say with this kit. The spacers up front, do not match the truck! Tech support? There is none! As for the name, Richeer, it is completely nonexistent! Please do not buy this product because you will have to pay the mechanic or waste an entire day trying to make this product fit to later realize you will have to return it! Revain should shut this outfit down!
