has anyone used these? and is this a difficult installation. i am a decent wrench but not mr goodrich. any suggestions? https://www.secureway1.com/alston/index.php?productID=196

Mine are bolt-on but don't look like those. Mine are straight and fit perfect. Got 'em at Summit. I think they're made by CE but I forget. And I welded them to the sub frame almost instantly when I tested them. No way was I ever going to get rid of them. Great addition. Do it!

I'm sure they're fine. But as stated above, weld them in after you've bolted them up. I can tell you from experience, it makes a big difference.
