Speedometers

This page holds aftermarket speedometers from AutoMeter and factory-style replacement assemblies from Crown Automotive. AutoMeter is the bulk of it: gauges for a dash or a custom panel, chosen by face size, dial range and style rather than by vehicle. The Crown Automotive units replace worn speedometers in older Jeep models.

For an AutoMeter speedometer, start with the hole. The face size comes first in each title, for example 3-3/8 inches, so measure the opening in your dash or panel before anything else. Next is the dial range and its units. The faces shown read 0-120 MPH, so check the scale on the listing if you want a km/h reading. Then pick the style. Series names such as Cruiser AD, Designer Black II and Old-Tyme White II describe the face and bezel, and using one series across the dash keeps the speedometer, tachometers and other gauges looking like a set.

Check how your vehicle drives its speedometer before ordering. Older vehicles usually turn it with a cable from the transmission; newer ones send an electronic signal from a sensor. A replacement has to accept the same kind of input, and an electronic unit may need to be calibrated after a tire or gear change. Sensors and senders for electronic setups are in senders and sensors.

The vehicle-specific listings are mostly for older Jeep models, including the Jeep CJ5, Jeep CJ7, Jeep Scrambler and Jeep Willys, with Crown Automotive assemblies for select Jeep vehicles. A few fit classic Chevrolet models such as the Chevrolet Impala and Chevrolet Bel Air. Each product page lists the years, makes and models it fits. Priced in Canadian dollars and shipped across Canada.

Mechanical and electronic speedometers, plus the drive gears, senders and adapters that make them read correctly — parts.

Speedometer error is the most common unintended consequence of a tire or gear change. Fitting taller tires makes the vehicle travel further per revolution, so an uncorrected speedometer under-reads — you are going faster than it says, and the odometer under-counts distance with it. A gear change does the same in the other direction.

The correction depends on the mechanism. A cable-driven speedometer is recalibrated by changing the drive gear at the transmission; an electronic one needs a calibration module or a tuner that can be told the new tire diameter and axle ratio. Establish which you have before buying — the two solutions do not substitute for each other.
