OK For The Price

I put these on my 2009 GMC Sierra. The install wasn’t bad and it took about 3 hours. I know some reviews said it could be done in an hour but I have to assume they were working in a garage with a lift and had power tools. Between breaking the rusted bolts loose and crawling around under the truck to run the lines, there’s no way I could have done it much faster. The air lines that came with the shocks were plenty long enough for my install. They gave me 10 feet of line and I used 6. The shocks held pressure for about a week and then popped a line out. During the install, I noticed that I could pull one of the lines after I thought I had tightened the nut down enough so I tightened it harder. That wasn’t the one that popped out so I’d recommend you check each fitting well during the install. I should have gone back and checked them all when I found that one but didn’t. You should tighten it down and give the line a good tug to try to pull it out. If it comes out, put it back and tighten it more. When you think they’re all good, put at least 100 pounds of pressure on them and see if they hold. I did that to all of them after the line popped and they held. I’ll update my review if they pop out again. Monroe should definitely improve the air line connections. To me, that’s the big issue with these. It’s really tough to tell whether you have them tight enough and it feels like it’s hit or miss for whether they’ll hold air for a long time because of that.
