Important: You must include your rear axle gear ratio and tire diameter in the "special instructions" box on your shopping cart page before checking out. This is crucial for us to determine the correct speedometer gears for your setup.
Important Shipping Note: All Tail Housings ship no earlier then the following business day. If ordered with other products, all other items will be shipped separately from the Tail Housing Kit. Shipments outside of the continental U.S. are charged on a case-by-case basis.
The mechanical speedometer 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.
Tail housing bolts can be added if needed. This is a simple 30-minute bolt-on installation.
