NHRA accepted! We use these billet spade and clevis units to make swing out door bars on cars that allow it. Our kits make it possible to "split" the door bar where it is most accessible to reach the pins. No need to go clear back to the cage with a tab, you can split it right at the seat for ease of use. Made from US steel and machined right here in Ohio, you can put these on your car with pride. Sold per side. Comes with a quality spring loaded "T" handle quick release pin and grade 8 hardware.
