      Superior Performance, Superior Economy. When you’re looking for a ring and pinion to take your 2005-2010 Ford Mustang GT’s performance where you need it, but still save wear and tear on your engine, you need the Nitro Gear & Axle Ring Gear and Pinion Kit – 3.73 Gears. With a heavy-duty construction and optimal gear ratio, you’re going to see power and performance at the ideal cost to your Mustang’s engine.

      3.73 Gear Ratio. This ring and pinion have a ratio that is ideal for providing performance, but also allowing for a good measure of fuel efficiency. This ensures that the power your engine delivers to your wheels isn’t consumed unnecessarily.

      Heavy-Duty Steel. To ensure maximum wear and tear resistance, this ring and pinion have been forged from 8620 steel. Its superior quality will keep you revving hard and fast for years to come.

      Recommended Upgrade. This ring gear and pinion kit will throw off your Mustang’s speedometer if it wasn’t already the gear ratio it had, so a tune-up will be necessary. This can be done professionally or a hand-held tuner can do it just as well, if you have one.

      Installation. This is a heavy-duty installation, requiring specialized hand tools, a car lift or jack stands, and advanced mechanical expertise. Please allow at least 4 hours to install if doing it yourself, but professional installation is highly recommended in this case.

      2-Year Warranty. This ring and pinion kit is protected by Nitro’s 2-year warranty, defending against manufacturer defects from the date of purchase. See Nitro Gear’s full warranty for complete details.

      Application. This Nitro Gear & Axle Ring Gear and Pinon Kit – 3.73 Gears is designed to fit 2005-2010 Ford Mustang GT models. Please ensure correct model and trim before purchase.
