What is a 6.50 gear ratio and why would I want it?

A 6.50 gear ratio means the driveshaft will turn 6.50 times for every one rotation of the rear wheels. This ratio significantly increases torque and improves acceleration, making it ideal for vehicles with larger tires or those used for towing and heavy hauling.

Does this gear set come with everything needed for installation?

This listing is for the ring and pinion gear set only. A separate installation kit, which typically includes bearings, seals, and shims, is required for proper installation and is sold separately.

Product Details

If you're looking to change the gearing in your Ford 9-inch rear end, this USA Standard Gear ring and pinion set is a solid option. It's designed to exceed OEM specifications and comes with a 6.50 ratio, which is a significant change from stock and will noticeably improve acceleration. This set fits a wide range of Ford vehicles, including popular models like the Ford Bronco, F-100, and Mustang.

USA Standard Gear puts all their sets through rigorous in-house testing to make sure they meet dimensional, material, and fitment standards before they leave the factory. This means you're getting a well-built gear set that's ready to perform. A 6.50 ratio is a popular choice for vehicles that have been modified with larger tires or are used for towing and need more torque off the line.

When installing a new ring and pinion, it's important to follow the manufacturer's instructions carefully, especially regarding the break-in procedure. This ensures the gears mesh properly and achieve their full lifespan. You'll also want to make sure you have the correct installation kit, which typically includes bearings and seals, to complete the job.
