This kit will give your 4L80E transmission a factory manual speedometer hook up that uses all new GM parts and does not interfere with any stock electrical configurations. The tail housing is the same length as the stock tail housing which means you can use your existing drive shaft. The kit includes new tail housing, drive gear, sleeve and driven gear, sleeve retainer, and bolt. Tail housing bolts can be added if needed. This is a simple 30 minute bolt on installation. Available with your choice of output shafts - A or B.
Important : You must include your tire diameter and rear axle gear ratio for us to determine the correct speedo gears! Use the chart below to find optimal performance.
