The Extreme Series air suspension kit is the ultimate slammed suspension system with the ability to lay frame on a 30” tire without compromising driving dynamics. The modular design replaces the factory crossmember and steering system with revised geometry and a narrowed track width for proper suspension function even at the lowest of ride heights. The kit features tubular control arms with adjustable cam bolts for alignment, mustang II rack and pinion for improved steering response, and our adjustable tie rod steering kit to eliminate all bump steer. Installation is a breeze as each kit is a bolt-on assembly with no welding required. We offer multiple engine mount options for effortless integration of your chosen powertrain.
