Mono vs. Multileaf Shock Plates

[ItDoRun]

What is the difference in mono leaf and multi leaf shock mounting plates? Can mono leaf plates be used when converting over to multi's?

i dont knwo the exact answer but everytime i see a post about people converting they cant find the multi leaf shock plate to complete the swap....but i dont know for sure...i remember seeing dse selling some

hey man i lost your number again i need to save it in my phone can you give it to me again thanks

It works for me. But I think they are thinner lateraly by a very small amount. sorry, just narrow.

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.

Thanks. I ordered a set of the multileaf plates last night from Rick's First Gen. just to be safe.

You rock! :firefire:

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

Are we talking shock mount plates or spring perches? doi

[Steve Chryssos]

Both.:doh:

Let me re-phrase my question. I will be converting over to a multileaf spring and was wondering if the shock plates for a mono leaf set-up will work. I know the spring perches are different, and I will be removing the existing mono perches and welding the new multi leaf perches on. It does appear to me that the shock mounting brackets hang lower on the mono plates. Bottom line is do I need to order the multileaf plates when I convert over?

Oops! Shock plates are the same.

[MrQuick]

Mono are abit narrower. Tad, schosh, etc

The mono-leaf shock mounting plates have the lower shock mounting hole roughly 1 inch lower than the multi-leaf plates. The mono plate is also made of thinner material steel than the multi-leaf plate. A few of the catalogs offer "shock extenders" for using the mono plates w/ multi-leafs. Just a few things I noticed.

I would just get the Multileaf Plates and be done with it.
