We have used these USA made JIMS transmissions in our builds exclusively for over two decades. In most cases we are using the 6-speed 'evolution Softail' transmission offered here. These babies feature overdrive with precision cut gears and improved shift drum and shift lever assemblies. Offered here we have transmissions with 'raw' cast case, polished case or textured black powder-coated case. All of these are supplied with polished aluminum covers and trap-door, but chrome is available on request. We can, of course, get any other transmission that is out there, so don't hesitate to call to discuss your needs.
