Hello all, I'm installing an MBRP dual cool T-409 cat back, when it ever gets here, and I was looking under the truck today and saw what looks like a dent in the downpipe. Might be factory dent to clear the cross member, but I don't know. What do ya ll think? The second picture is my stock 2500HD leaf/ubolts. I would like to lift the back about two inches. I've read where some people received the wrong ubolts, (wrong diameter or length), and I'd like some input as to what and where I can get some correct 2" blocks and ubolts. Also, do I have to install a pin/bolt down the middle to hold everything together? Thanks, Mac

Anyone else here ever install a block under their rear leafs??? I could use a little help with this. Mac

I'm sure there are kits made to lift the rear.


Why do u want to lift it?


Since u have a service body u may want to install extra spring or two, more capacity and still have your lift.


Still use stock u bolts.


When we lifted trucks, I made my own blocks and had a local spring shop make the correct u bolts.


The blocks use the stock spring pin in top and a dowel pin in bottom to keep axle alignment.


Does this cover all your ??
