2 Our rear suspension supporting our DTS-built Dana is a kit from Unlawful Racing. It's a new triangulated four-link coilover rear suspension that is specifically designed for A-, B-, and E-Body Mopars. This rear suspension system is a self-contained unit that utilizes the original front leaf spring mounting points with its own sub frame that fits between the original frame rails. The sub frame requires minimal welding, and is a breeze to install. Their triangulated four bar system is completely adjustable for ride height, stance, tire clearance, pinion angle, instant center and more, making it appealing to all forms of racing and street applications. Their system allows for more tire clearance without tubbing your wheelwells.
