Heidts Pro-G Independent Rear Suspension Kits IRC-800

The Heidts Pro-G independent rear suspension kit, part IRC-800, centers on a cast-iron Ford 9-inch center section mounted in an aluminum housing, paired with tubular steel control arms, single-adjustable rear coilovers, and Wilwood brake rotors and calipers. What comes with this base kit Coilover springs arrive in a silver powder-coat finish, and a 0.875-inch sway bar is included for roll control; a panhard bar and watts link are not part of this IRS layout, since the independent design does not need one. This is sold as a base kit, so differential internals and axle shafts are not included and need to be sourced separately, and you specify your preferred spring rate when ordering. What to check before ordering Your chassis dictates whether the control-arm brackets bolt on or need a weld-in fit, and polyurethane bushings run throughout the arms either way. Because this is a base kit built around a Ford 9-inch housing, confirm what differential internals, axle shafts, and brakes you still need to add before your build is complete. Does this kit include the axle shafts? No, this base kit does not include axle shafts; they are sourced separately. Can I choose my own spring rate? Yes, you specify the spring rate you want when you place the order. Specifications Feature Details MFG.
