Yukon Gear High Performance Gear Set For Model 35 in a 4.56 Ratio

Yukon Gear Ring and Pinion Gear Set for Model 35 in a 4.56 Ratio

The YG M35-456 from Yukon Gear and Axle is a high-performance ring and pinion set built for the Model 35 (Dana 35) rear differential in a 4.56 gear ratio. If you run a Jeep Cherokee XJ, Wrangler TJ, Jeep Liberty, Dodge Dakota, Ford Explorer, or Ranger and want to restore or upgrade your gearing, the YG M35-456 delivers precision-machined teeth, high-grade steel alloy, and an OEM-spec fit that drops right into your 7.5-inch ring gear housing. Yukon engineers this set in-house using two dedicated quality labs to confirm tooth geometry, surface finish, and load tolerance before the YG M35-456 ships. Whether you are regearing after a lift, correcting speedometer error from bigger tires, or rebuilding a worn differential, this 4.56 ratio set gives you the crawl ratio and highway RPM balance you need for serious off-road use.

Frequently Asked Questions

• Q: What differential does the YG M35-456 fit?
  A: It fits the Model 35 (also called Dana 35) rear differential found in many Jeep, Ford, Dodge, and AMC vehicles from the late 1960s through the mid-2000s.
• Q: What is the spline count on this gear set?
  A: The YG M35-456 uses a 27-spline pinion to match the standard Dana 35 carrier configuration.
• Q: Does a 4.56 ratio make sense if I have 35-inch tires?
  A: Yes. For a vehicle with a stock 3.07 axle ratio, stepping to 4.56 with 35-inch tires restores close-to-stock driving feel and significantly improves trail torque.
• Q: What additional parts do I need to install the YG M35-456?
  A: You will need a master install kit (bearings, seals, shims), gear marking compound, and access to a gear setup tool. Check whether your carrier requires a break for the 4.56 ratio.
• Q: Will this void my vehicle warranty under the Magnuson-Moss Warranty Act?
  A: Under the Magnuson-Moss Warranty Act, a dealer cannot void your powertrain warranty solely because you installed an aftermarket part. They must prove the aftermarket part caused the failure.
• Q: How do I break in the YG M35-456 after installation?
  A: Allow gear oil to reach operating temperature during a 15-minute idle. Drive 500 miles avoiding sustained high-speed highway loads, then change the gear oil and inspect.
• Q: What warranty does this product carry?
  A: Yukon covers the YG M35-456 against manufacturing defects for one year. The optional Y.E.S. plan extends coverage for the life of your ownership.
• Q: Is professional installation required?
  A: Yukon strongly recommends professional installation to ensure correct gear pattern, backlash, and bearing preload settings that protect the YG M35-456 long-term.

Installation Instructions

1. Raise and safely support the vehicle. Drain gear oil from the Dana 35 differential.
2. Remove the axle shafts and mark the driveshaft-to-yoke orientation before unbolting.
3. Remove the differential cover and clean the housing thoroughly.
4. Measure and record existing ring gear backlash and pinion bearing preload for reference.
5. Remove the bearing caps, differential carrier, and existing ring gear set.
6. Press the old pinion bearing off the pinion shaft and install new bearings from the master install kit.
7. Set pinion depth using shims and a dial indicator until the gear pattern is centered per Yukon specs.
8. Install the new ring gear from the YG M35-456 set onto the carrier, torquing bolts in a cross pattern to spec.
9. Set carrier bearing preload and adjust backlash to 0.006 to 0.010 inch using side bearing shims.
10. Verify the gear contact pattern with marking compound; adjust as needed.
11. Reinstall the cover with a quality RTV or gasket. Fill with the correct gear oil to the full mark.
12. Reinstall axle shafts, driveshaft, and wheels. Torque all fasteners to specification.
13. Follow Yukon break-in procedure before returning to normal driving.
