ROADSTER SHOP SPEC SERIES KITS FOR 1960-87 CHEVY C10 ARE DESIGNED TO DELIVER AN AGGRESSIVE 4.5- TO 5-INCH RIDE HEIGHT—NO NEED TO CUT, C-NOTCH OR STEP YOUR ORIGINAL FRAME AND WORRY ABOUT KEEPING EVERYTHING SQUARE. If you choose the air bag suspension option, you’ll be able to lay frame using a 29-inch-tall tire.
Each kit has a full-perimeter TIG-welded frame with precision CNC laser-cut and contoured frame rails. That makes them stronger and lighter than mandrel-bent tubing frames with no kinks, bends or stress areas. A more rigid frame means your suspension will work better, too.
