Custom tuning by a qualified speed shop is normally a good fix for both of these issues.

The new gearing can affect transmission shift points as well (on automatic transmissions, but this is a non-issue for manual transmissions). If the gearing in your differential is changed in a significant way, then the speedometer calibration is likely to be affected which will make your speedometer inaccurate.

The main negative aspects of installing 4.10 gears lie in performing transmission modifications in general. Depending on the transmission that you have installed, you might even be able to adjust the overall gearing so that the final drive of your car is nearly the same while in overdrive, but allows you to take advantage of the new gearing in the lower transmission gears. If your car is equipped with an overdrive, you may not even notice a difference in gas mileage with the new higher gearing. Installing 4.10 gears improves the carвЂ™s performance on the track but with negligible effects to the highway driving. This equates to a greater amount of power transferred to the wheels. Therefore, the higher the ratio (4.10 gears compared to 3.55 gears) the higher the gearing and the greater number of rotations before the rear wheels turn. The gear ratio is the ratio of how many times your engine has to turn the crankshaft to turn the rear wheels one rotation. Gear ratio has a great deal to do with how your car performs and handles under load. Most late model Mustangs and many other sports cars come equipped with standard 3.55 gears in their rear differential, however by adding 4.10 gears they can effectively make their drag times faster and deliver more power to the wheels faster. Tto be a serious threat at the drag track, it is necessary to upgrade your gearing to at least 4.10 gears.
