Threaded Spring Pins: Greaseable threads prevent spring from moving side to side within the shackle. Our exclusive design threads the pins directly into the spring bushing providing much more stability, improved feel and overall handling. The Largest Door Openings: that make it easier and safer to get in and out of the truck. Forged Steel Door Hinges: Internally mounted protection from the elements. Greater durability to prevent sagging -- a common problem with piano hinges. Double Door Seals: Both the door and the cab have a weather seal that covers its perimeter. This double seal helps maximize the efficiency of our HVAC systems and provides a quieter ride. Grade 8 Frame Fasteners: Grade 8 fasteners allow for optional equipment to be installed on the frame, and retorqued in the field as needed.
