Mono vs. Multileaf Shock Plates

[The Rook]

I thought that the mono leaf plates have the shock mount lower by 2 or 3 inches. I believe there's info on Pozzi's website about this.

Don't do it. The perch is designed to surround all four sides of the leaf spring (in conjunction with the shock plate). Mono-leaf perches are shorter in depth since they only need to surround a single leaf. When using mono perches with multi springs, the sides of the leafs are exposed, so the u-bolts carry all of the load. The u-bolts are only intended to clamp the perches to the shock plates--not carry the entire load. Those bolts could shear.

If you are not in a position to convert them (welding is required), then at the very least, build some simple spacers to fill the gap between the perches and the shock plates.

I've wondered about that when I see mopars and late trucks that just have the flat spring perch that offers no latereral support.
