The Gen 3 SHO uses 3 different springs for the front and 3 different springs for the back. It is generally agreed that the later Gen 3 SHOs ('98 & '99) have stiffer springs especially the '99 non SARC SHO.

The info I have gathered is below. It apears that the middle number gets smaller as the spring rate increases. What would be in an inverse relation to spring rate stiffness that this number would represent? I assume the other numbers being the same for it's own group is the length and width but I don't know.

Fronts Rears
M=4927 5=2446
H=4564 6=2525
J=4685 L=2288

'96 most MM66, some MM55
'97 most MM55
'98 most HHLL
'99 most HHLL some JJLL
