This Top Marker wheel features our combination of Diamond Vinyl/Smooth Vinyl Grip for a “Sure Grip”” feel. It also has two holes pre-drilled and ready to mount 11/16″” sized switches. The holes are shipped with plastic plugs just in case you only need a one button set up. Note: This wheel is pictured with an optional Quick Disconnect Kit. This wheel does not come with a horn button or part number 4000 GT Styling sleeve. It was designed to be used with our Racing Quick Disconnect Kits.
