how many inches will back end rise using ac delco part number 504 -557 ?Alex p.Feb 23, 2023
Best Answer:Hi Alex, I'm glad to assist you. A maximum of 4", but this will mainly maintain the ride height with up to 1,100 lbs (per pair) of additional temporary leveling capacity to help improve vehicle handling and reduce the risk of undercarriage damage. I hope this helps, and if you're interested in this set of air shocks, you can click on the link below for direct ordering to take advantage of our ongoing discount and limited stocks.
