Is your McGaughys lowered 2004-2008 Ford F150 squatting when it's loaded? Still want to tow with your lowered truck? Need a little pick me up in the rear? Then add a McGaughys Suspension rear air bag helper kit to increase payload and add the ability to fine-tune your stance. When hauling a trailer or heavy load, the bags can be inflated to "pick-up" the rear of your vehicle, eliminating any rear end sag, bottoming out or bumpy ride. Each kit includes the helper airbags along with all necessary brackets, hoses and mounting hardware. This air bag helper kit is made in the USA and is backed by a one year manufacturer warranty.
