When you’re looking for a high-quality ring and pinion set upgrade for your 1999-2004 Ford Mustang GT, the Nitro Gear & Axle Ring Gear and Pinion Kit – 4.30 Gears are what you need. Their high-quality combination of an aggressive gear ratio and sturdy steel 8.80-inch construction provides you with the way to unlock your vehicle’s power in the most efficient manner possible.
4.30 Gear Ratio. This ring and pinion kit utilize a 4.30 gear ratio to keep your Mustang’s power consistent if you’re mounting bigger tires or several other ways of improving performance. This will ensure that your engine’s power is delivered properly to your wheels.
Durable Steel. This kit is forged from heavy-duty 8620 steel. It’s used for superior protection and lasting strength to power your Mustang through the high-powered performance you put your vehicle through.
Recommended Upgrade. If you use this ring and pinion to add a different gear ratio to your original one, you will need a tune-up since your Mustang’s speedometer will not be right. You can fix this with a personal tuner if you have it handy.

Allow about 4hours for complete installation if installing yourself, but due to the complexity of the job, professional installation is highly recommended.
