I purchased and used 1 month. Purchased from Tony here on the forums. Belltech rear lowering springs. Rear shock relocation brackets. In box never installed Airlift 60742 air bags. Asking $350.00 or reasonable offer for all buyer pays shipping. Or if you are near the Lehigh Valley PA area for pickup. I can post pics if needed. They were great on the truck, my pickup died so now I’m going to tow with this truck and prefer the stock height for this issue alone.
