Made exclusively from genuine Eaton 18 speed shifters and adapted to work with a computer, these are top of the line, real truck parts. Magnets are used inside to trigger signals instead of buttons, creating virtually no wear and tear on electrical components. We DO NOT SELL THESE WITH THE BALLS ON TOP. Those are purchased separately to help our turnover time. At times we will have ball toppers available on the site, but we recommend buying them from "Twisted Shifterz" online. When ordering select 1/2"x13 for the thread and it will screw right on top of the shift knob. Colored skirts now available as well for a $15 add on. (a chrome skirt is the standard) You can add a high quality metal and chrome side button for $20 since chrome easy jakes are not available anymore. Included is the shift knob, USB harness and shift knob adapter. (unless you order with an extension) Be sure to read the policies page on our site before ordering.
