I've got ONE(1) brand new icon 2.5" rear piggy back reservoir shock up for grabs. Most places sell these as a pair, but you can call Metal-Tech (or pretty much anyone else...) and they will gladly sell you another one.
PM me an offer!
Here is the exact shock on Icon's website.
4Runner 2.5" Piggy Back Reservoir Shock
Preference to local buyers. But I will ship.
