Not so supreme????
Both blocks had the incorrect sized hole for the leaf springs nipple to fit into the block and both blocks pins were too long stopping it from sitting flush on its perch and created about a 1/4” gap under itself. Maybe i just got the one kit that got missed in QC but i ended up throwing the whole kit away bc the aluminum got damaged from the install.

Awesome brand
Reason for 3 stars is, I had to drill out the hole for me struts and cut down the peg on the bottom to make the fit. Other than that they were extremely easy to install and got me where I wanted to be

Fit but required work
Lift worked great after i ground down the little button on top. It was too tall to fit flush in the existing block

2 inch rear lift
Very satisfied. Super easy install. The only worry I have is that the blocks are hollow. I installed the lift in my driveway with a floor jack. Then went for a short ride around town. Got back home and retightened the bolts. They were very loose after the ride. I had already raised the front up 2.5 to level it up. I didn't like the level look so I decided to raise the back up 2 inches above factory. It came out great. I am very happy. If you have air tools it will take about 30 mins. But I don't.

Wrong size
Says it fits a ram 2500, but these are more like universal nt for my truck. I had to drill holes in blocks to fit my truck and then the u bolts are not wide enough for my axel. I think these are 3.5 inch and the ram 2500 diesel is 4" axel diameter. Other than that they look ok.
