Review on ACDelco Specialty 504-550 Rear 🚗 Air Lift Shock Absorber: Superior Suspension Enhancement by Dave Hersma

Review updated. In the beginning they were great. After less than 2000 miles, however, they were no longer holding air. When I got to my destination 2 hours away, half the psi was gone. The warranty process was a nightmare. Be prepared to phone back and forth when Amazon's return window closes. Ac Delco will say Amazon is responsible. Revane will say AC Delco is responsible. It is best to contact the curator immediately. Chief csr is incompetent Old review. I regularly tow an RV and a boat. Not very heavy objects. However, my butt sagged embarrassingly. I'm sure the sufferer might need to add a leaf to relieve stress, but these kicks really worked. No more sinking to the bottom or looking like my truck is flying in an airplane. Excellent price.
