Eibach Pro-Truck Reservoir Rear Shock - Chevrolet Colorado / GMC Canyon 2015-2022

This is the reservoir version of Eibach's rear Pro-Truck damper: the same monotube high pressure design and heavy duty 46mm piston, but with an external piggyback reservoir that adds oil volume and sheds heat, so damping holds up over a long washboard road instead of going soft. Billet aluminum fittings, rod ends and reservoir clamps carry the plumbing, the body is zinc coated, and the increased travel design is built for a lifted truck running 0 in to 1.5 in of rear lift. Sold individually.
