Yukon Dana 60 Reverse Cut Thick Ring & Pinion Gear Set
YG D60R-456R-T
The Yukon Dana 60 Reverse Cut Thick Ring & Pinion Gear Set is designed for high-pinion Dana 60 front axles requiring deeper gearing without changing from a 4.10-and-down carrier. Available in 4.56, 4.88, 5.13, and 5.38 ratios, these thick-cut gear sets help restore lost torque multiplication after installing larger tires while improving low-speed control for rock crawling, rock bouncing, desert racing, and heavy-duty off-road builds. The reverse-cut design is engineered specifically for compatible high-pinion front axle applications.
Manufactured from precision-machined, heat-treated alloy steel, Yukon ring and pinion gears are built for reliable tooth engagement and durability under demanding drivetrain loads. The thicker ring gear offsets the carrier mounting difference, allowing deeper ratios to be installed on compatible 4.10-and-down Dana 60 carriers. Whether you're re-gearing a Ford Super Duty, upgrading a custom Dana 60 axle, or building a dedicated crawler, proper carrier compatibility, pinion depth, backlash, bearing preload, and gear contact pattern are essential for long-term performance.
Includes:
- (1) Dana 60 Reverse Cut Thick Ring Gear
- (1) Matching 29-Spline Pinion Gear
- Selected Gear Ratio: 4.56, 4.88, 5.13, or 5.38
Important: These are reverse-cut thick gear sets designed for compatible 4.10-and-down Dana 60 carriers. They are not interchangeable with standard-cut gears or standard-thickness gear sets intended for a different carrier break. Installation bearings, seals, shims, and overhaul components are sold separately unless otherwise specified.

Fitment
Designed for compatible Dana 60 reverse-cut high-pinion front axle applications using a 29-spline pinion and 4.10-and-down carrier. Vehicle year and model alone do not guarantee compatibility, especially across Ford Dana 60 and Super 60 axle generations.

Fitment Notes:
- Fits compatible Dana 60 reverse-cut high-pinion front axle applications
- Thick ring gear design for 4.10-and-down (3-Series) carriers
- Available in 4.56, 4.88, 5.13, and 5.38 ratios
- Requires compatible 29-spline pinion configuration
- Not interchangeable with standard-cut Dana 60 ring and pinion gears
- Not intended for low-pinion standard-rotation rear axle applications
- Ford Super Duty and Super 60 applications require axle-specific verification
- Confirm axle identification, carrier break, pinion spline count, and gear configuration before ordering
- Front and rear axle ratios must match on four-wheel-drive vehicles
- Professional gear setup is recommended
Builder Note: The thick gear configuration is especially useful when retaining an existing 4.10-and-down carrier while upgrading to deeper gearing. However, not every Ford Super Duty front axle uses the same Dana 60 gear set. Confirm the actual axle generation and pinion configuration before selecting a ratio.
FAQ
What is a thick ring and pinion gear set?
A thick gear set uses a ring gear with additional thickness to compensate for the mounting offset between different carrier breaks. This allows deeper gear ratios to be installed on compatible carriers originally designed for numerically lower ratios. These Yukon Dana 60 thick gears are intended for 4.10-and-down carriers.
What is the difference between reverse-cut and standard-cut Dana 60 gears?
Reverse-cut gears use a different tooth geometry designed for high-pinion axle applications. Standard-cut gears are generally used in low-pinion configurations. The two gear designs are not interchangeable and must match the axle housing.
Will these gears fit my Ford Super Duty Dana 60 front axle?
These gear sets are designed for compatible Ford Dana 60 reverse-cut front axle applications. Because Ford used different Dana 60 and Super 60 configurations, verify the axle model, pinion spline count, and carrier compatibility before ordering.
Can I use these gears with my existing 4.10 carrier?
Yes, provided your axle uses the compatible 4.10-and-down Dana 60 carrier and reverse-cut gear configuration. The thick ring gear design allows deeper ratios to be installed without changing to a standard 4.56-and-up carrier.
What gear ratios are available?
Available ratios are 4.56, 4.88, 5.13, and 5.38. Each ratio is sold as a matched ring and pinion set with its own Yukon part number.
Which gear ratio should I choose for larger tires?
The correct ratio depends on tire diameter, transmission gearing, transfer case ratio, engine power, vehicle weight, and intended use. Numerically higher ratios provide more torque multiplication and improved low-speed control, while numerically lower ratios generally maintain lower engine RPM at highway speeds.
Are these gears suitable for rock crawling and rock bouncing?
Yes. Dana 60 reverse-cut gear sets are commonly used in high-pinion front axles on rock crawlers, rock bouncers, trail rigs, and competition vehicles. Proper installation and matching the gear ratio to the drivetrain are essential for reliability under high torque loads.
Do these gear sets include bearings and installation hardware?
No. This listing includes the selected ring and pinion gear set. Bearings, races, seals, shims, and other installation components are sold separately unless specifically noted.
Do I need to change my front and rear gears together?
On a four-wheel-drive vehicle, the front and rear axle ratios must match. If you change the front differential ratio, the rear axle must also have a matching ratio before engaging four-wheel drive.
What is required for proper Dana 60 ring and pinion installation?
Proper installation requires setting pinion depth, pinion bearing preload, carrier bearing preload, backlash, and the ring and pinion tooth contact pattern. Incorrect setup can cause gear noise, excessive heat, premature wear, or gear failure. Professional installation is recommended.
