Review on 🔧 ACDelco Specialty 504-554 Rear Air Lift Shock Absorber: Enhanced Suspension Support for Optimal Comfort and Performance by Chad Carter

I have been towing a caravan for about four years now and although I have fitted new shock absorbers with external assist springs attached, the rear of the truck tended to sagging over any bump in the road even though I was using a weight-distributed hitch. However, these upheavals changed everything. Now walk calmly and don't stop. I couldn't be happier with the purchase.
