Hey man. I am in the Greenville area and have a pair of OME 891s I just took off my runner. Been on for 2 or 3 years. They have certainty settled by this point but aren't getting an worse. Still in really good shape and perform/handle really well. I'd say around 2" of lift. Maybe a little more. They have been super good to me and the only reason I am switched is because my Runner is heading in a more road-unfriendly setup. Going with Toytec Superflex (if i can actually fit them. they are huge). If you want them they are all yours.
If you want to pay for shipping or pick them up either works for me. Though they are free and used, they are still worth putting under a rig. The only tip I would suggest if putting some air bags for heavy loads. When 2 buddies and I are loaded up to camp and kayak (2 kayaks each. got have your surfer and your big shit runner) for a few days the rear end gets pretty damn low. Besides some heavy towing though that load is pretty much the max you could experience. Still had an inch of so of axle clearance and made it from the Upstate to WV/KY/MD many times. The 891s are "heavy duty" springs but they still sag a good amount when full loaded.
With the Bilstein 5125s extended travel shocks (got them off Toytec a few years ago) you get a bunch of badass flex out of that setup. I mean a lot of flex.
