Designed to optimize drivetrain performance, this high-performance ring and pinion gear set enhances torque delivery and traction, making it ideal for off-road enthusiasts and those upgrading their vehicle’s power or tire size. Yukon’s commitment to quality ensures that this gear set delivers reliable, long-lasting performance under demanding conditions.
Whether you’ve increased horsepower, installed larger tires, or simply want to improve your Wrangler’s overall drivability and traction, this gear set offers a precise gear ratio that balances power and efficiency for a superior driving experience.
Yukon Gear & Axle’s Hi-Perf Gear Set incorporates advanced engineering and manufacturing techniques to meet the highest standards in the automotive gear industry. Key features include:
This gear set is crafted from premium-grade alloy steel, selected for its high tensile strength and resistance to fatigue. Yukon employs state-of-the-art heat-treating techniques that harden the gear surfaces while maintaining a tough core, resulting in gears that withstand extreme torque loads and harsh off-road conditions. The precision machining process ensures perfect tooth alignment, minimizing backlash and maximizing gear mesh efficiency. The result is a gear set that delivers smooth, quiet operation and long service life.
The Yukon Hi-Perf Gear Set is designed as a direct replacement for the factory ring and pinion gears in Jeep Wrangler JK models from 2007 through 2018 with the specified engines. Installation requires professional gear setup tools and expertise to ensure proper backlash and gear pattern adjustments. No modifications to the axle housing or differential are necessary, but it is recommended to replace differential bearings and seals during installation for optimal performance and reliability.
This gear set is ideal for Jeep Wrangler JK owners who have upgraded their engine performance, installed larger off-road tires, or seek improved torque and traction for trail or street use. It suits enthusiasts looking for a durable, high-quality gear upgrade that maintains drivability while enhancing power delivery and off-road capability.
Yukon Gear & Axle supplies hardcore drivetrain components—ring & pinion gears, axles, lockers, and differential upgrades—built for off-road and high-load performance. Trusted by enthusiasts and installers, Yukon focuses on fit, strength, and proven options for re-gearing and reinforcing trucks and 4x4s running bigger tires and tougher terrain.
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
