Pro Comp Explorer ES1000 Shock Absorber 118055

Got this Pro Comp Explorer shock absorber sitting around. It's the ES1000 series, part number 118055. It's definitely seen some use and has some rust spots on the body as you can see in the photos, but the shaft looks decent. Not sure what it came off of exactly but these are pretty common for lifted trucks and SUVs. Selling as-is if anyone needs a spare or a cheap replacement for a project rig.
