Yukon Gear High Performance Gear Set For Dana 60 Reverse Rotation in a 4.30 Ratio / Thick

Yukon Gear Ring and Pinion Set for Dana 60 Reverse Rotation in 4.30 Ratio Thick

The YG D60R-430R-T from Yukon Gear and Axle is a high-performance reverse-rotation ring and pinion gear set built for the Dana 60 front differential in a 4.30 ratio with a thick-cut gear design. The Dana 60 front differential equipped in Ford F-250 and F-350 trucks uses reverse-rotation gearing because the front pinion spins in the opposite direction from conventional rear axles, and the thick designation in YG D60R-430R-T means the gears are sized for carriers used with numerically higher ratios beginning around 4.10. Ford F-250 and F-350 trucks from 1978 through 2015 are the primary application, including both classic body style trucks and Super Duty models. Yukon engineers this set from premium steel alloy with precise tooth geometry validated in two dedicated in-house labs. When you are regearing the front of a heavy-duty Ford truck to match a rear axle ratio change, the YG D60R-430R-T is the correct direct-fit solution.

Key Features and Benefits

• Reverse-Rotation Design: Required for Dana 60 front differentials in 4WD Ford F-250 and F-350 trucks
• Thick Gear Cut: Sized for higher-ratio carriers starting around 4.10, ensuring proper fit without additional machining
• 4.30 Gear Ratio: Strong torque multiplication for heavy towing, large tires, and off-road use in Super Duty applications
• 35-Spline Pinion: Matches Dana 60 heavy-duty carrier specifications for maximum torque handling
• High-Grade Steel Alloy: Premium material withstands the extreme loads placed on Dana 60 axles in heavy trucks
• Dual Lab Testing: Every set verified for dimensional accuracy and structural integrity before shipping
• Y.E.S. Plan Eligible: Optional lifetime no-questions-asked warranty coverage available

Frequently Asked Questions

• Q: What does the "T" in YG D60R-430R-T mean?
  A: The T designates a thick gear cut. The YG D60R-430R-T thick design is required for Dana 60 carriers used with gear ratios numerically higher than approximately 4.10.
• Q: Why does this Dana 60 gear set use reverse rotation?
  A: Ford 4WD trucks mount the Dana 60 front differential with the pinion on the opposite side from a conventional axle, requiring reverse-rotation gears to achieve forward vehicle motion in 4WD.
• Q: What spline count does this pinion use?
  A: The YG D60R-430R-T uses a 35-spline pinion, which is standard for the heavy-duty Dana 60 axle found in F-250 and F-350 applications.
• Q: Must I regear the rear axle at the same time?
  A: Yes. Front and rear axle ratios must match for proper 4WD operation. Install a matching 4.30 gear set in the rear differential at the same time.
• Q: Can the dealer void my warranty for installing the YG D60R-430R-T under Magnuson-Moss?
  A: The Magnuson-Moss Warranty Act requires the dealer to demonstrate that the aftermarket gear set caused the failure. Simply installing the YG D60R-430R-T is not grounds for a warranty denial.
• Q: What other parts will I need?
  A: A Dana 60 master install kit with bearings, seals, and shims is required, along with gear marking compound and a dial indicator.
• Q: What warranty comes with the YG D60R-430R-T?
  A: One year against manufacturing defects. The Yukon Y.E.S. plan extends coverage to lifetime protection.
• Q: Is professional installation recommended?
  A: Yes. Dana 60 front differential setup requires precise reverse-rotation pinion depth, backlash measurement, and contact pattern verification that demands specialized tools and experience.

Installation Instructions

1. Safely lift the vehicle and drain gear oil from the front Dana 60 differential.
2. Disconnect the front driveshaft and remove the front axle shafts, marking all orientation references.
3. Remove the differential cover and clean the housing.
4. Record existing backlash and pinion preload as a baseline.
5. Remove bearing caps, carrier, and old ring and pinion set.
6. Install new pinion bearings from the Dana 60 master install kit onto the YG D60R-430R-T pinion.
7. Set pinion depth using shims and a dial indicator per Yukon specification for the thick-cut reverse-rotation design.
8. Install the new ring gear onto the carrier and torque ring gear bolts in a cross pattern to specification.
9. Set carrier preload and adjust backlash to 0.006 to 0.010 inch using side bearing shims.
10. Verify gear contact pattern with marking compound and adjust as needed.
11. Reinstall cover with RTV or gasket. Fill with the specified Dana 60 differential fluid.
12. Reinstall axle shafts and driveshaft, torquing all fasteners to specification.
13. Follow the Yukon break-in procedure before sustained towing or off-road use.
