Part #: YG D30JL-488R
The Yukon Gear & Axle Ring & Pinion Gear Set with a 4.88 ratio is engineered specifically for the 2018–2019 Jeep Wrangler JL models equipped with either the 3.6L V6 or 2.0L Turbo engines. Designed for off-road enthusiasts and performance seekers alike, this gear set enhances your vehicle’s drivetrain to optimize torque delivery and traction, especially when paired with larger tires or increased horsepower. Yukon’s commitment to precision and durability ensures that this gear set meets the demanding conditions of both street and trail use.
Whether you are upgrading for improved crawling ability, better acceleration, or to maintain proper driveline geometry after tire upgrades, this ring and pinion set provides a reliable and long-lasting solution. Backed by Yukon’s Y.E.S. Plan, it offers lifetime coverage, giving you confidence in your investment.
This Yukon ring and pinion gear set incorporates advanced engineering and manufacturing techniques to deliver superior performance and durability. Key features include:
Yukon Gear & Axle utilizes advanced metallurgy and precision CNC machining to produce ring and pinion gear sets that withstand the rigors of high-performance and off-road driving. The gears undergo a rigorous heat-treating process that enhances core strength and surface hardness, ensuring long service life under extreme loads. The exacting quality control measures guarantee consistent tooth geometry and alignment, which translates to reduced gear noise and improved drivetrain efficiency.
The design focuses on durability and reliability, making these gears suitable for both daily driving and demanding off-road conditions. Yukon’s engineering team continuously refines the manufacturing process to maintain the highest standards in the industry.
This ring and pinion gear set is a direct fit replacement for the front or rear differentials of 2018–2019 Jeep Wrangler JL models with 3.6L V6 or 2.0L Turbo engines. Installation requires professional tools and expertise to ensure proper gear pattern and backlash settings. It is recommended to have the installation performed by a qualified technician familiar with differential gear setups to achieve optimal performance and longevity.
Upgrading to a 4.88 gear ratio is especially beneficial when larger tires are installed, as it helps restore the vehicle’s powerband and driveline balance without compromising reliability.
This Yukon ring and pinion gear set is ideal for Jeep Wrangler JL owners who have upgraded their vehicle’s tires or engine performance and want to maintain or improve driveline efficiency and traction. It suits off-road enthusiasts seeking better crawling capability, daily drivers looking for smoother acceleration, and anyone aiming to extend the durability of their drivetrain components under increased load conditions.
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!
