Speedometer, Tachometer Cables and Re Calibration Units

Speedometer Calibration

Speedo and Tach cables. Our experience has enabled us to have a open purchases order from a fortune 500 company to manufacture a control tip for their manufacturing process. We make cables for industrial, automotive and marine. Our longest cable was 40 feet for a tach drive on an lake freighter and our shortest is only 3 3/4 inches long for an industrial application. We use strictly American made product.

Does your speedometer read 70 and you are only doing 55? We can help solve this problem very inexpensively!

Important Speedometer Pre-Calibration Instructions

You must operate your vehicle on a highway with mile marker post or signs. Record how many miles and 10th of miles that your odometer says at the start of the test.

Drive your vehicle for five miles (the speed does not matter for this test) and record your odometer distance after driving five miles, give us that information by calling 1-800-283-2839 and we will quote you pricing for the correction adapter and cable if needed.
