Get rid of your poor-performing leaf springs with our custom trangulated 4-bar system. By separating the locating system from the spring, it's possible to drastically improve geometry, traction, and handling while using a much lighter spring and shock to provide excellent ride quality and wheel control. Our system requires no cutting to weld in a single crossbar between the factory frame rails. Coil-overs mounted ahead of the axle eliminate wheel hop normally associated with 4-bar systems, yet allow stock gas tanks to fit. Axle housing not included, but is available separately.
