If you're diving into a rebuild or just looking to boost your ride's performance, you might want to check out the USA Standard ring and pinion sets. These aren’t just any gears; they're designed to bring a level of confidence to your install that you can actually feel when you're behind the wheel. Whether you’re working with a common setup or something a bit more obscure, USA Standard Gear has got you covered with a solid lineup.

For those of you with a 1993-1999 Ford, you’ll be happy to know this set fits the 10.25-inch axle perfectly. The ring gear diameter is, as you'd expect, 10.25 inches, which means it’s built to handle some serious torque. With a 31 spline pinion and 12 ring gear bolts, this setup is sturdy enough to take on whatever you throw at it. And if you're looking to change your gear ratio, this one comes in at 4.56, which is great for getting that extra oomph when you hit the gas.

Plus, you can ride with peace of mind knowing there's a 1-year warranty against manufacturer defects. That’s a nice touch when you’re investing in your vehicle’s performance.

So, if you own a Ford E-250 from '85 to '98, an E-350 from '85 to '98, or even a F-150 from 2000 to 2004, this ring and pinion set is definitely worth considering. It also fits F-250s from '85 to '99 and F-350s from '85 to '97, as well as the '99 ZG models. In short, if you’re looking to enhance your ride with some reliable and robust gearing, this is a solid option.
