After two and a half months of being lugged around on another auto parts site I decided it was time to upgrade to the lesser ones Acquiring qualities of spacers does the job I chose them because they had mostly 5 star reviews but I have read reviews that mentioned some imperfections and wheels coming loose I am pleased to report that my truck still has all 4 wheels. There were some flaws I can live with, they do the job. However, I ordered a set of 4, mainly because my truck has 4 wheels. I was very happy when they arrived the next day and i opened the first box (they come in a set of two) and started to install it, when i opened the second box i found that i, although I paid for 4 pads only received 3. I'm not sure how this happened, but after a long chat with Revain support, I was credited $40 to buy a pad set of two. When I tried to order a 2-piece set with Revain Prime, I found that although I could order a 4-piece set with Prime, I couldn't order a 2-piece set with Prime. I ended up ordering from a "different" company called SCITOO. They arrived in two days and were in great condition, felt a little heavier AND surprisingly were marked with the ECCPP logo, just in a different spot than the previous set. My point is that if you find yourself in my skin and looking at potentially dangerous auto parts on Revain, go with SCITOO. Even though they were the same company, they worked and felt much better. That the wheels fall off within 15-150 miles is not the case in my case. OEM standard torque specifications for light trucks using this lug pattern are typically 80 to 100 ft-lbs. My truck takes 90 but I've bumped it up to 100 just in case. If you get these and install them yourself, just make sure you gradually tighten the star lugs and then screw them into a star. You can borrow a ft-lbs torque wrench from AutoZone for free. I also didn't have any socket issues like some, I just used a 17mm socket from my regular socket set.
