 Surplus Stock of clusters, speedos, tachs and small gauges, including a few Mercedes clusters (reduced prices) We also have an authentic reproduction of Jeep temperature gauges.

       We services GM clusters, 1989-2009, for  $169-$189For locals: if you call ahead, we can service while you wait!   For others, same day turnaround if you ship UPS.   We also service Ford and Chrysler clusters, as well a many foreign instruments.

       Automotive clocks can be converted to quartz or custom fabricated into a tachometer or other type gauge.  Note:  We do not repair clocks - just quartz conversions.

        Cables and housings for just about any application except power seat cables and window cables.  We also offer Cable X, a simple solution for customers with a mechanical speedometer in a vehicle equipped with an electronic speedometer signal.  

        Custom ratio adapters for speed correction are available for most vehicles.   Also, see a few GM Ratio Adapters..  Our Electronic Speed Adapter (ESA) corrects a speedometer that's inaccurate due to a change in tire size or rear axle ratio.  The ESA is compatible with most cars and trucks and is a snap to install.

        Instructions have been provided here for conducting a Ratio Test which will tell you if your error is in the speedometer gauge itself or if it's caused by cable delivery from your transmission.  In general, if the tires or transmission, including differential, has been or will be altered, the ratio must be adjusted.

            There's also a Troubleshooting Guide to help in identifying your gauge problems.
