Are these supposed to go with OME springs in place of the SL spacer?

If you're looking to add height to the superlift, I would not use these with OME springs Or the spacers.
They achieve lift by adding pre-load to the spring (like the SL spacer does). So i'd ditch the spacer, use stock springs, and set them at the 1.5" lift setting for a 5" superlift, or 2" lift setting for a 5.5" superlift.

lol sounds like a plan.
Hell, bring over a set of those shocks and we'll throw them on
OK I'm rethinking my "no cutting coils" stance.
Crunched some numbers and here's what I think would be a great addition to the superlift spacer:
5100's with OME MD springs with 1 complete coil cut.
The issue with stock springs is the spring rate is lacking for added accessories... so some stiffer springs are desirable. The OME HD springs have a rate of 630 lbf/in. If I take an OME MD spring and cut one complete coil off, the resultant spring rate will be 600 lbf/in which is nice because it adds load capacity over the stock springs but still won't be as stiff as the HD's.
Ideally i'd hope that the OME MD springs, with one coil cut, and 5100s set to .75" would put the superlift right around 5"....then you could get 5.5 or 6" by adding preload via the 5100s.
If its too tall, more could be cut off the spring... i'd say bring it up no further than the OME HD rate of 630 lbf/in.
Standard OME springs:
OME990 = MD = 14.56" free height , 8.9 coils, 530 lbf/in, 18mm wire
OME991 = HD = 14.37" free height, 8.9 coils, 630 lbf/in, 19mm wire
More info:
Cutting ~1.5 rotations off the OME MD springs brings their rate up to 630 lbf/in, and a free height of 12.10"
Cutting ~1.0 rotations off the OME MD springs brings their rate up to 600 lbf/in, and a free height of 12.92"
IIRC, the spring compartment in the stock/OME struts are ~11.75" long. The 5100s are going to have a smaller compartment since they add pre-load for the lift, so the 12.10" length of the 1.5 cut OME990 spring is OK.
