10-04-2017: UPDATE on the new G2.2 Bezel. Great news... found a new shop to cut our aluminum inserts and they are on their way to us presently. WE also found a new chrome shop that apparently is the best in the business...and after I explained the difficulty we've had with other chrome outfits, we sent them a couple of sample bezels... they agreed to help us out. That's the good news... because they are helping us out providing our customers with the highest quality of plastic chrome looking application, they informed us that our parts (24 at a time) won't take priority over existing larger projects, however they did promise to get them done as soon as they could and get them back to us as quickly as they can... they will be slipping these in among other larger chroming projects... needed to be upfront and honest.. we have everything we need to deliver this item... but have no control over speed of chroming and we cannot ask them to hurry... they are doing us a favor by taking on our products.... We've had orders backordered since January of this year... and I wish there was a faster solution but this is the right one to insure a quality part. Once they get rolling... we should be knocking these out between 30-60 days from order date... we're just not quite there yet... thanks for your patience.

3-3/8" Programmable Speedo Features

Speedometer features two trip meters and odometer (miles). A  remote mount TRIP/CALIBRATION button is included. Calibration is as easy as  pressing a button and driving one measured mile. Just recalibrate the  speedometer whenever changes are made and the speedometer will automatically  adjust for the changes and accurately indicate speed. Marshall speedometers come  calibrated for 16,000 pulses per mile.

Marshall electronic speedometers are designed to work with both  hall effect senders and magnetic pickup sensors. Any speed sender or electronic  module that meets the following conditions can be used with our speedo:

  •   Pulse range generated proportional to the vehicle speed
  •   Signal with minimum 3V peak to peak signal - typical for 3-wire    hall effect and 2 wire vehicle speed sensor outputs
  •   4000-200,000 pulses per mile (16,000 is typical).
