I have 5100 tundra with about 3.5 lift in back. I'm going to replace with 4th gen 5160. You need extended bump stops and taller springs for those. I think 3rd gen 5160 will work for 2.5-3" with OME 890 with stock bump stop. I only got these 5100 because 5160 were out of stock and I had blown one of the rears and needed something quick.

Forgot to say I have 3rd gen 6112 in front, which gave me about 2.75 for some reason. It can be very bouncy going slow but rides great at speed, like bombing down dirt roads or on the interstate. Very flat driving. It can go straight over pot holes and speed bumps (in an building development with no houses or anything yet) at 50mph no prob (with E-rated KO2s). The progressive valves or whatever I suppose. I don't like the boat-like feel of soft shocks, I drive my 4runner like a go-cart most of the time tbh.
