This Kit Includes:
Speedometer Info: Changing your Mustang's gear ratio will throw off your speedometer calibration. An SCT Handheld Tuner can correct this.
Pinion Bearing:In 2010, Ford changed the rear pinion bearing in their 8.8 rear end. This means, the rear pinion bearing include in this install kit will NOT work with your 2010+ Mustang. The correct rear pinion bearing is Ford Part #9L3Z-4630-A and can be order through your local auto supply store.
