If you’re serious about getting the most out of your Jeep, you’ve probably heard of Yukon Gear & Axle. Their high-performance ring and pinion gear sets are pretty much the gold standard in the automotive gear world. I’ve had my fair share of experiences with different brands, but there’s something about Yukon's commitment to quality that stands out. These guys really know what they’re doing.
What sets Yukon apart? For starters, their engineering team uses cutting-edge design software and advanced heat-treating techniques to craft gears that can handle some serious power. I’m talking about structures that are built to last, with a surface finish that meets some pretty strict standards. It’s not just about making things look good; it’s about performance and durability.
And let’s talk about that Y.E.S. Plan. If you’re like me and tend to push your ride to the limits, this lifetime protection plan is a lifesaver. It covers your gear set for as long as you own your vehicle, no questions asked. That kind of peace of mind is hard to come by.
Whether you’ve cranked up the horsepower, slapped on some bigger tires, or just want your Jeep to grip the road better, Yukon has a gear ratio for you. They offer a wide selection, and I’ve found that the 5:38 gear ratio is perfect for my setup. It fits reverse rotation Dana Spicer 44 axles, which is a nice touch for those of us who like to get a little adventurous off-road.
- Axle Type: Semi Float
- Cover Bolt Quantity: 12
- Gear Ratio: 5.38
- Mounting Hardware Included: No
- Nested Gear Family: Yes
These gears fit perfectly in the Jeep Gladiator (2020-2023) and Jeep Wrangler (2018-2023). If you’re rolling with a YG D44JL-538R setup, you’re in for a treat with these Yukon ring and pinion gears. They’ve really upped my Jeep’s game, and I can’t recommend them enough if you’re looking to enhance your ride’s traction and performance.
