They fit me perfectly and installation was easy. I installed them on my 2010 F-150 with a 6" Rough Country suspension. I installed 18" wheels on a 2015 FX4 and needed spacers to bypass the tie rod. After installing them I realized I could use a thinner washer and it would still work. So I only used them for two weeks and then switched to 1.25" ECCPP spacers. I've been using them for a couple of weeks now with no problems. The 1.25s gave enough clearance for the tie rods so I'm sticking with them. .Note: if you are using 1.25" spacers and factory aluminum rims you will need to cut 1/4" off a nut to make it work. Now they are immediately impressive in terms of quality. Apparently they were carefully made from one Aluminum block milled. Milling is neat clean and precise. The black finish looks very nice. It comes with studs and nuts and for my truck they matched the original. That way I was able to use the nuts they sent to fix the spacer on the truck truck and use my 'nice' nuts to attach the wheel to the spacer, I would definitely recommend them to anyone who wants spacers!
