A MUST have for anyone running tire sizes different than stock.  Our speedometer calibration modules allow for accurate speedometer readout on the dash no matter how large your tires are.  We send these out pre-programmed for your specific tire size.  Should you change tire sizes at a later date simply send us your module and we will re-program it for the new tire size free of charge.  

These install in five minutes and require no special tools or equipment.  Save yourself the stress of a speeding ticket and enjoy the peace of mind knowing that your speedometer is accurate no matter what size of tire you are running.  In stock now!

**Please specify your tire size and year of van when placing your order and we will pre-program the module prior to fulfillment.
