Give Your Truck The Torque It Deserves

If you’ve pushed your truck to the limits with bigger tires or extreme terrain, the Yukon YGD80-513 Ring and Pinion Gear Set is exactly what you need to bring that power back where it counts. With a steep 5.13 gear ratio, this setup is built to help your truck launch harder, crawl slower, and pull heavier with less strain on the drivetrain. It’s a go-to choice for off-road builds, rock crawlers, and rigs that need serious torque down low. Whether you're driving a 1999-2016 Ford F250 or F350, or a 1994-2002 Dodge Ram 2500 or 3500, this gear set gives you the control and grunt your factory gears just can’t match. Yukon builds every set with durability in mind, using high-strength materials and precision cuts for smooth, quiet performance under load. The 5.13 ratio is perfect for compensating after a tire size jump, helping restore RPMs and drivability both on and off pavement. If your truck works hard or plays harder, this upgrade gets the job done right.

Designed For Heavy Loads And Serious Crawl Power

The Yukon YGD80-513 Ring and Pinion Gear Set is engineered for Dana 80 rear axles and delivers a 5.13 gear ratio tailored for extreme-duty applications. With an 11.25 inch ring gear diameter and a 37 spline pinion, this set offers the strength and surface area needed to handle high torque loads without compromise. It's an excellent match for Ford Super Duty models from 1999-2016 and Dodge Ram 2500 or 3500 trucks from 1994-2002, especially those running large tires or used for demanding tasks. The 12 bolt ring gear provides solid, consistent mounting, keeping the gear firmly secured even under heavy stress. Yukon uses advanced manufacturing techniques to produce gears that run quieter and last longer, even in punishing environments. The 5.13 ratio significantly lowers final drive, offering more usable power at lower speeds for rock crawling, heavy towing, or working in tough conditions. Each set is sold matched for proper wear patterns, ensuring long-term reliability and smooth engagement.
