What add a leaf did you use for the rear? How much lift is it going to give? I need to get rid of my 3" blocks.dstrbdone said:Well I finally got my IRS check today. No longer will my HP d44 have to sit in the garage. It felt so great to start ordering parts to finally build it up and install it. I also ordered a add a leaf to add to my Chevy leafs in the rear now that I got rid of the blocks. I never rotated my waggy knuckles so now finally the front driveshaft angle will be fixed and no more vibrations with the High pinion installed. Now I have just as good an excuse as any to go out this weekend and wheel the guts out of the waggy axle. Sorry but I just had to tell somebody the goodnews. I have been waiting forever to get the money to install this axle. And my wife just don't understand. She likes to wheel and all but she doesn't get excited like me about new truck parts.
