9 way adjustable shocks

I have 4 of these 9 way adjustable shocks. 2 are new in box, 2 have been on for 1 yr, still in good shape since it has been in the garage for the last 6 mo. They are Rusty's brand but are identical to the Ranchos. The in cab remote for the RS9000's will work with these. They measure 30" eye to eye when extended, 17.5 when collapsed. I could tell a big difference when I switched out the hydros with these. $150 for all 4. Free shipping to business address.

are these the ones, that adjust stiffness? what size lift where these used with?

Yes, the higher you turn them, the stiffer they get. I have the 6.5" lift.
