Monroe Shocks & Struts MA705 Max-Air Shock Absorber. Condition is “Used”. Working condition. One of bushings is a bit dried out: see photo. Installed by previous owner. Used on my 69 Mercury Cougar before I changed rear springs and bought performance shocks.
The Max-Air shock absorber is ideal for vehicles that haul heavy loads or tow trailers. Designed to maintain level vehicle height, they can be inflated or deflated as needed…from 20 psi to 150 psi with the vehicle loaded. Capacity is limited by vehicle suspension, tires and transmission. See vehicle owner’s manual for details.Lower Mounting Code: Stem Mount - 2.3/8" Stem Length X 3/8"-16 Thread Pitch
