Product Details
When you're looking to get the most out of your Jeep Wrangler's drivetrain, especially after adding larger tires or increasing horsepower, a proper ring and pinion gear set is key. This Yukon Gear & Axle set is specifically designed for the Dana 44JK rear axle found in 2007-2018 Jeep Wranglers, offering a 3.21 ratio. This ratio is often chosen to bring your Jeep's gearing back closer to stock performance after installing larger tires, helping to restore acceleration and fuel efficiency.
Yukon engineers use high-grade steel for both the ring and pinion gears, and the tooth surface finish is designed to reduce friction and heat buildup. This attention to detail in materials and design helps ensure a long service life and reliable performance. The fitment is designed to OEM specifications, meaning it should install cleanly into your Dana 44JK rear axle housing. This set includes the ring gear and the pinion gear, ready for installation.
This ring and pinion set is a significant upgrade for your Jeep Wrangler's rear axle. It's a solid option if you're looking to re-gear after tire upgrades or simply want to optimize your Jeep's performance. Remember that re-gearing typically requires specialized tools and knowledge, and it's often recommended to replace the pinion seal and bearings during the installation process. Yukon Gear & Axle also backs this set with their Y.E.S. Plan, a lifetime, no-questions-asked protection plan.
