If you're looking to beef up your Jeep's drivetrain, the USA Standard ring and pinion set is a solid choice. These gears are built for the standard rotation Dana Spicer 30 with a short pinion, so you know you're getting a fit that's meant to last. I’ve seen these in action, and they really do the trick when you want to get more power to the ground.

• Designed specifically for the Dana Spicer 30 with a short pinion—no guesswork here.
• The ring gear has a 7.20-inch diameter, which is a nice balance between strength and weight.
• It comes with a 26 spline pinion, and let me tell you, that means solid engagement.
• With 10 ring gear bolts, you can trust that everything stays snug and secure, even when you're pushing your Jeep through tough terrain.
• This set has a 4.88 ratio, which is perfect for those of us who like to tackle steep trails or haul heavier loads.

Plus, you get a one-year warranty against manufacturer defects, so you can install these with a bit of peace of mind. Just make sure you’re rolling with the right models: this gear set fits Jeep Cherokee from 1996 to 2001, Jeep Grand Cherokee from 1996 to 2004, and Jeep Wrangler from 1997 to 2006. If you’ve got a ZG D30S-488TJ, you’re in good hands with this Dana 30 ring and pinion replacement gear set. It’s a straightforward upgrade that can really change the way your Jeep handles, especially if you’re running bigger tires or tackling more challenging trails.
