Review on 🚗 Enhance Your Ride with ACDelco Specialty 504-562 Rear Air Lift Shock Absorber by George Bell

They don't lift much under load, but they greatly improve the truck's stability on the freeway, and when not loaded at the correct setting (psi) they offer a smoother ride. They leak a little on the fitting, but I can't fault the original equipment that came with the shocks as I use an air lift system with fittings made on the dumb threads on the shocks.
