Yukon Gear High Performance Gear Set For Dana 44 in a 4.11 Ratio

Want 4.11 gears in a Dana 44 that already has a 3.73-and-down carrier, or replacing worn gears in a 2003-2006 Wrangler TJ Rubicon? The Yukon Gear & Axle YG D44-411T is the thick-gear version of the Dana 44 4.11 ring and pinion. Its ring gear is made thicker so it bolts to the 3-series carrier, so you can step up to 4.11 for 33 to 35 inch tires without buying a new carrier. It is a new set for standard rotation Dana 44 axles: 8.50 in. ring gear, 26-spline pinion, 10 ring gear bolts.

What the thick 4.11 gear set does in a Dana 44

Dana 44 carriers come in two series. Ratios of 3.73 and numerically lower use the 3-series carrier; 3.92 and deeper normally use the 4-series carrier, because the smaller pinion lets the ring gear sit closer to the axle centerline. A thick ring gear makes up that difference, so a 4.11 set fits the 3-series carrier. That matters when your locker or limited slip is a 3.73-and-down unit and you do not want to buy another. At 4.11:1 the driveshaft turns 4.11 times per tire revolution, enough to bring back power and drivability on moderately larger tires.

If your axle already has a 3.92-and-up carrier, this is the wrong set. Use the standard-thickness Yukon Dana 44 4.11 set instead.

Symptoms this re-gear fixes

• Sluggish launches and constant downshifting after moving to 33 or 35 inch tires
• Gear whine on drive, coast or both from worn ring and pinion teeth
• Pinion bearing rumble or play at the yoke, often replaced along with a gear change
• Chipped or broken teeth after hard wheeling, common in TJ Rubicon axles run on big tires

How to confirm before you buy

Pull the cover and identify the carrier: the ratio tag and the stamped number on the ring gear tell you what is installed now, and the carrier series decides whether you need this thick set or the standard one. Confirm the axle is standard rotation and that the pinion yoke takes 26 splines. Our tire size and gear ratio guide helps check that 4.11 is the right number for your tires, and the Dana 44 rebuild cost guide covers inspection for noisy axles.

Fitment

Yukon's fitment notes for YG D44-411T read "Thick Ring and Pinion Set; 26 Spline Pinion; Fits 3 Series Carrier." The list covers the same broad range of standard rotation Dana 44s as the other ratios: early Bronco and Ford truck fronts, Chevrolet and GMC K-series trucks, Blazers and Suburbans through 1980, Dodge W-series, Ramcharger and 1994-2002 Ram fronts, Scout 800 and II, Jeep CJ, Wagoneer, Grand Wagoneer, Comanche and 1986-1993 Cherokee rear, and 1997-2006 Wrangler TJ Dana 44 rears. It is also listed for both the front and rear Dana 44 of the 2003-2006 Wrangler TJ Rubicon. It does not fit reverse rotation high-pinion fronts or JK and JL axles.

Install notes

• Keep the 3.73-and-down carrier, or use a matching traction unit such as the Detroit Truetrac 30-spline, 3.73 and down. A 3.92-and-up carrier will not work with a thick gear.
• Replace all bearings, races, the crush sleeve, the pinion seal and shims. TJ Rubicon owners can do both axles with the TJ Rubicon Dana 44 overhaul kit.
• Revolution Gear lists 0.042 in. starting pinion depth for the standard D44, 14-19 in-lb new pinion bearing preload, 0.006-0.010 in. backlash and 60 ft-lb bearing caps. Since the ring gear is thick, plan on changing pinion and carrier shims to get the pattern right.
• Re-gear the other axle to 4.11 too on a four-wheel-drive vehicle.
• Fill with 75W-90 or 75W-140, add friction modifier only for a clutch-type limited slip, break the set in gently per our ring and pinion break-in guide and recalibrate the speedometer.

What does the T in YG D44-411T mean?

It is the thick-gear version. The ring gear is made thicker so a 4.11 ratio bolts to the Dana 44 carrier made for 3.73 and numerically lower ratios.

Can I use this with a 3.92-and-up carrier?

No. With a 3.92-and-up carrier you need the standard-thickness 4.11 set. The thick set only works on the 3.73-and-down carrier.

Does it fit the 2003-2006 TJ Rubicon?

Yes. Yukon lists it for both the front and rear Dana 44 of the 2003-2006 Wrangler TJ Rubicon.

What tire size works with 4.11 gears?

4.11 is a common choice for about 33 to 35 inch tires, depending on engine, transmission and how the vehicle is used.

Do I need new bearings?

Yes. Install new pinion and carrier bearings, races, a crush sleeve and a pinion seal along with the gears. Reused bearings rarely hold the preload a new set needs.
