Ratio Adapters

Long before the days of digital dash clusters and dummy lights, cars used mechanical gauges. In order for mechanical speedometers to work, it has to be able to "talk" to the transmission. the ratio adapter is the "translator". If you have changed your tire size, rear-end gears, or transmission, your speedometer is most likely lying to you, which can get you the 1-finger salute from fellow travelers, or even worse... a ticket from "The Boys in Blue".


We custom build all of our own ratio adapters, so whether yours just wore out or you need something completely different to fit a custom application, you came to the right place. we only need 3 things from you:

  1. Tangs/Tips (Square or Round? Size in Thousandths)
  2. What Type? (Straight Thru, Off-Set, 90°)

3.   Ratio Required? (Actual Speed) / (Display Speed) = (Your Ratio)


The easiest way to compare the actual speed and the display speed is to use the speed given by a GPS as your actual speed, and the speedometer as your displayed speed.  There are other ways to test this, if you can't get access to a GPS, give us a call and we can talk you through the other options.
