|Where can I
purchase speedometer cables and how can I calibrate my
Speedometer cables may be purchased at RJay's or your local auto parts store. Auto Meter speedometers come with a standard 5/8" x 18 threaded cable input that requires a .104" sq. male drive. The speedometer is calibrated for a 1:1 drive ratio (1,000 RPM at 60 MPH input at the speedometer head.)
If the vehicle tire size and/or
rear end differential are not stock, a different driven gear in
the transmission may be required for speedometer accuracy. If a
change in the driven gear is made, you very likely will also
have to change the drive gear in the transmission to maintain
the proper gear tooth arrangement. Another approach is to use a
"correcting ratio" drive joint to adjust the
speedometer input to 1,000 RPM at 60MPH. The ratio can be
determined by comparing your speedometer reading against another
car having an accurate speedometer and dividing the same speed
(Accurate speed / Your speed = Ratio needed.) Auto parts stores
or speedometer specialty shops (see above) carry
"correcting ratio" drive joints.
