I have the factory non-tsb leafs, with an AAL right now. I'm starting to get annoyed at the stiffness. They seem really bumpy to me. I've also got an axle wrap issue that I haven't been able to remedy. And the squeak.. f*ck! everytime i drive off pavement my shit sounds like metal grinding metal, regardless of cleaning & lube. driving me nuts.
Bottom line, I'm looking at full leaf packs to start fresh.
I've read good things about all pro, and im not loking to spend $600 on some springs. I know that these aren't designed to handle weight...but I'm wondering - is there any difference in weight capacity between the 1.5" and the 3"? Or any difference in ride stiffness?
