Not bad for the money, had to change bottom two holes by 1/4" on both fronts (cause 4* not 5*). The plastic is pretty soft (I modified mine with a pocket knife). Not sure how they will hold up against big rocks flying off the tires. Speaking of tires, if you have aggressive 33-inch tires and don't have a 2-inch front leveling kit, I promise they're going to rub. Mine is clean but not much with the alignment kit. Rotate the front wheels to install the front and I had to raise the back a bit to get the 1/4" ratchet t15 in the back. I have airbags and an airbag in my truck and a fully inflated litter was enough. They're worth what you pay for, after all, they're not $150 junk.
