The Extreme Series air suspension kit is the ultimate slammed suspension system with the ability to lay frame on a 31” rear tire without compromising driving dynamics. Installation is a breeze as each kit is a bolt-on assembly with no welding and minimal cutting required.
The rear kit replaces the rear section of the frame and replaces it with a stronger and stiffer frame section with a taller c-notch for added axle clearance and added crossmembers that locate suspension and airbag components. The factory frame is cut just behind the cab and the new frame rails and crossmember lock to the original frame by encapsulating the inside and outside of the frame rails creating a strong and redundant connection with no welds to perform and potentially fail. The Extreme system allows provisions for one or two piece drivelines and adjustable suspension geometry for dialing in driveline and handling setups.
