These premium black crinkle wing nuts prominently display the Mopar "M" Emblem in signature blue inlaid paint. The head of each wing nut also has been modified into a pentagon shape that goes back to the early days of the Chrysler Pentastar. These small design cues set these valve cover wing nuts apart from the competition. The lower ends of the wing nut shafts are manufactured with wide shoulders for broader load distribution, and each wing nut is supplied with a separate stud which permits precise gasket positioning on the head prior to mounting the valve covers. Fits Chrysler LA, B, and RB Engines. 1/4in x 20 threaded studs are included. 4 per package.
