I am installing a 5" Superlift on my 02 screw. I started doing the back today and the u bolts are not long enough. I have 4" blocks and add a leafs. I used to have an 01 with 6" fabtech and I had no problems. My 01 also had add a leafs. Has anyone else ran into this problem? Also, the rear brake line on the driver's side is tight. Not sure what is going on here. My 01 was very easy, less than an hour to do.

 

did the kit come with a 4" block and AAL or just one of them? some companies give you ubolts that are just the right length with no extra length for an AAL or larger block.

 

it came with the block but not the aal. my fabtech worked with both with the ubolts that came with the kit. i took off the factory block and it works fine now. i might get longer ubolts made depending on how the trucks sits when i get the front done.
