Commonwealth Chassis Work's signature full slam air ride chassis is engineered with quality as the forefront. Internally gusseted and structured frame rails, crossmembers and frame stiffeners ensure that our components are manufactured in spec with strength in mind. Ditch that old tired C channel frame for a fully box and overlapped frame built to handle high HP engines and sports car like handling. 

Our front tubular control arm suspension and rear parallel 4-Link with watts link will keep you truck planted to the road and is engineered for a quality ride throughout its 8" of suspension travel. The air ride suspension is designed to sit the rocker and lowest portion of your bed sheet metal on the ground while tucking up to a 29" tall tire. The front control arms accept any 1973-1987 C10 drop spindles of your choosing which allows for a vast array of brake options from OEM, WIlwood, and Baer. Rack and pinion steering is provided by a Mustang II steering rack (manual, or power option).  Cam alignment adjusters on the upper control arms allow for ample camber and caster adjustment. 

All of our chassis components are CNC Laser cut, and CNC bent with high precision to ensure quality fit and finish prior to welding. 3/16" and 1/4" Canadian made steel construction throughout. All of our chassis are hand assembled on our chassis jig table to  for an exact fit up prior to welding.
