Ratio Adapters and Cables

If you have had transmission work done on your vehicle or if you have changed the tire size or differential gear ratio your speedometer and odometer readings may be incorrect. We can help you correct your speedometer and odometer readings on most pre 1990 vehicles.

Just send us your calibration test results and we can build you a custom ratio adapter to correct your speed readings. AAA Auto Club and other similar dyno testing facilities can perform these tests on your vehicle. Or you can drive your vehicle on a marked highway for 10 miles and record the mileage that your odometer recorded.

Adapters can be built for GM and Dodge Trucks prior to 1988 and many GM and Chrysler vehicles prior to 1990. Adapters can also be used on Fords, Toyotas, Nissans and other vehicles, although installation may not be as simple. Please call us or Email us for more information.

Slimline drop angle ratio adapters now available! These adapters can be squeezed into tight spots and are perfect for your street rod.  Call for details.
