Full Size Jeep Network

Hello, New to this web site. Bought a 73 j4500 a few years ago and have been slowly working on it. I have considered boosting the suspension to a j4600 or 4700. have a question about the leaf post points, are they all the same of did the heavier trucks have larger post for the leaf springs. Thanks Paul

Welcome to the forum!

There is two different size posts used. And it almost seems random as to which vehicles got which sized posts.

To my knowledge, only Hell Creek sells springs for the post mount FSJs (BJ's may resell them as well). As part of the ordering process, you have to tell them what size post you have so that they can put the correct sized bushing into the springs. Hell Creek does offer an FSJN discount which they posted here: viewtopic.php?t=2865
