For STEPPER MOTOR REPAIR KIT:Set of 6 Switec Stepper Motors, part number x27.168 (not aftermarket black type). Most 's have six gauges and you'll need one motor for each gauge in your instrument cluster to complete the job. While you're in there you may as well replace all the stepper motors because they're all guaranteed to go out eventually. Once one goes out it's not long before the rest go too. Fits ALL 2003-2006 Silverados, Suburbans, Tahoes, Trailblazers, Yukons and many more listed below. DIRECT FIT: Direct replacement for the older and faulty XC5168, X15168 and X25168 stepper motors that came in millions of vehicles produced from 2003-2006. These X27 168s have been redesigned for maximum reliability and quiet operation. This set is enough to repair all the gauges in a 6 gauge instrument cluster such as a Silverado 1500 and many others. These stepper motors are for the repair of the speedometer, tachometer, oil pressure gauge, transmission temperature gauge, battery voltage gauge, water temperature gauge or fuel gauge.
