Yukon YG D60R-430R-T Dana 60 Reverse Thick Ring & Pinion 4.30 Ratio 4.10-Down

Vehicle Fitment

• 1978-1999 Ford F-250 (4WD, Dana 60 front reverse rotation axle)
• 1979-1997 Ford F-350 (4WD, Dana 60 front reverse rotation axle)
• 1999-2015 Ford F-250 Super Duty (4WD, Dana 60 front reverse rotation axle)
• 1999-2015 Ford F-350 Super Duty (4WD, Dana 60 front reverse rotation axle)
• 2000-2013 Ford F-450 Super Duty (4WD, Dana 60 front reverse rotation axle)
• 2000-2013 Ford F-550 Super Duty (4WD, Dana 60 front reverse rotation axle)
• 2002-2015 Ford F-250 Super Duty (4WD, Dana "Super" 60 35-spline front axle)
• 2002-2015 Ford F-350 Super Duty (4WD, Dana "Super" 60 35-spline front axle)

Fitment Notes

• Fits reverse rotation (high pinion) Dana 60 and Dana "Super" 60 front axles only - standard rotation (low pinion) Dana 60 gears will not work in this application
• This is a THICK gear set - designed for use with the 4.10 & down (3-series) carrier case, allowing the 4.30 ratio to be run without purchasing a 4.56 & up high carrier
• The Dana 60 has a carrier break at 4.10/4.56 - if your front differential has a 4.56 & up carrier, a standard (non-thick) 4.30 gear set is required instead
• Front gear ratio must match rear gear ratio for correct 4WD operation - pair with appropriate rear ring and pinion set
• A master install kit with pinion bearings, races, seal, and crush sleeve is required and sold separately
• Verify your specific axle (standard Dana 60 vs. Dana Super 60 35-spline) before ordering - both are covered by this gear set

Features

• Thick ring gear tooth profile allows 4.30 ratio use on 4.10 & down carrier cases without a high carrier swap
• Reverse rotation (high pinion) design engineered specifically for Ford Dana 60 and Super 60 front axle applications
• High-grade alloy steel construction in both ring and pinion for long-term durability
• Advanced heat-treating and precision CNC gear tooth finishing to reduce friction and heat under load
• Engineered to OEM specifications for accurate fitment, proper contact pattern, and quiet operation
• 4.30 ratio delivers improved low-speed torque for towing, off-road, and large tire applications
• Eligible for Yukon's Y.E.S. Plan lifetime warranty (available separately)

Product Description

The Yukon YG D60R-430R-T is a high-performance thick 4.30 ratio ring and pinion gear set for the reverse rotation (high pinion) Dana 60 and Dana "Super" 60 front axles found in 1978-2015 Ford F-250, F-350, F-450, and F-550 Super Duty 4WD trucks. The "R" designates reverse rotation - a critical distinction for the Ford Dana 60 high pinion front axle; standard rotation gears are not compatible. The "T" designates Thick - a thicker ring gear tooth profile that allows the 4.30 ratio to be used with the factory 4.10 & down (3-series) carrier case, bypassing the need to purchase a 4.56 & up high carrier case.

The 4.30 ratio is a popular first-step regear for Super Duty owners running 35"-37" tires who want to restore stock-like throttle response, towing performance, and drivability without going to the expense of a carrier swap. Yukon manufactures these gear sets from high-grade alloy steel with advanced heat-treating and precision CNC finishing, engineered to run quietly and last under the high-torque demands of diesel and gas-powered Super Duty trucks. Confirm that your carrier is the 4.10 & down series before ordering, and match this front gear to a compatible rear gear set for correct 4WD operation. A master install kit is required and sold separately.
