We hear it all the time. It seems like new trucks keep getting higher and higher from the factory. Many people complain about the lack of space between the bed rail and their 5th wheel. Some people just hate climbing in and out of the truck, even with running boards. With a front and rear air suspension system and an electronic air control system, you can lower your stock height truck approximately four inches to make getting in and out much easier!
Check out the video below to see a customer that came to us with a problem and we provided them with a solution. This new Ram 2500 with our front and rear air suspension installed along with the Hadley SAMS 4X4 Electronic Air Control System allows the truck to drop nearly four inches at all four corners. . This combination made a world of difference for this customer who was looking to get in and out of his new Ram without a hassle.
