how to tell difference in pep zps and mass limited

[DnB_racing]

Im in the process of purchasing a set of pep shocks for my 450 and Im curious how to visually tell the difference between the massflow and the zps ....
the ones im getting have 4 springs and a remote 8 click reservoir and from all the pics Ive seen both mass flow and zps have these options..
any help would be great Ive looked at a bunch of pics and I cant see any difference

im pretty sure yours are zps they look exactly like the shocks on my 250r although i could be wrong cause on the resi's for my shocks its engraved zps and my weight and mx so i could be wrong

heres a direct quote "The 'Zero Pre-Load System' is our unique design that has adjustable ride height so the chassis can be set at a low ride height while having long travel."

im pretty sure the limited mass shocks arent adjustable for ride high like the zps

I will have to check for any markings when i get them,,thanks for the info 89trx.... how do you like yours?

The ZPS shocks have 4 springs and the top one is really small and is always bottomed out while sitting on the ground that is the ZPS spring. The limited mass shocks won't have that.
