Using this air suspension kit is easy. First, install it according to the instructions, which should take about 2.5 hours. When you're using your vehicle for normal driving, the air bags will help level the load, up to 5,000 lbs. If you're not towing and want a super - comfortable ride, you can run the air bags at 0 psi. Now, about the bump stops. If you're worried about losing air bag pressure and bottoming out, the bump stop acts like an insurance policy. But if you need maximum travel in your air bags, like when hitching up trailers or going off - road, you can choose the version without bump stops. As for maintenance, keep an eye on the air bags and the end caps for any signs of corrosion or damage. And always make sure you don't go over the manufacturer's recommended Gross Vehicle Weight Rating. That way, your air suspension kit will serve you well for a long time with its lifetime warranty.
