American Automotive3" Rear Suspension Lift Steel Blocks + Extra Long 12" Square Leaf Spring Axle U Bolts

Insanely easy install, and the quality of the metal seems high. My only complaint is that the size of the bolts is a 9/16" instead of 5/8", so there was a little slop in the washers after install in a 1-ton Chevy Express. Otherwise, the finish is great and I expect these to last many years.

Had a small issue with u bolts being too short...contacted company and they had me ssnd back old ones and sent me out longer ones...these people are great...excellant communication and speedy response...they truly care about their customers

2001 chevy 1500 ext. Cab..Fit perfectly. I used them as replacement bolts and not for lift.

Make sure the taper < bigger to the back > other way around will pull the drive shaft out of the extention housing.

Easy to install I put these on my 05 Chevy LS 1500 and it’s held up excellent.

I put everything together one night. It was about 11 I got everything in, ready to put in the u bolts and finish up. Not realizing I should measure them before hand, I didn’t. The u bolts were stock. 3 inches too short. This cost me a day off work. If you’re gonna buy this you’ll probably need U bolts. The blocks seemed pretty durable but how do you mess that up. I think I deserve 3 inch longer I bolts. I didn’t want stock ones. I’m buying a lift kit.

Poor install directions

Solo corté las grapas 2" cada una de resto todo lo demás muy bien
