Just purchased B code springs and would like to know how to do the B mod on the springs. What is the difference in ride and height between B mod and 3.5" rear blocks. Can I use my existing Rancho 9000x shocks....Thanks
Take your Ex spring pack apart to get all the 1/8" thick spacers from in between the leaves. You also need the 2 bottom leaves from the Ex pack. (Not the Ex anti-wrap leaf, the 2 arched leaves above that.) Install the spacers and the 2 Ex leaves in the B pack.

You need longer U bolts, center pin and shocks..I developed this mod in '04 and have helped thousands fix the Excursions handling issues.
If I can help please PM-email me.
