Yukon Gear Dura Grip Limited Slip for Dana 44 - 30 Spline - 3.92+
A Dana 44 with an open carrier or a tired factory Trac-Lok leaves a Jeep Cherokee, TJ Wrangler, Scout, Bronco or older Dodge, Ford or Chevy 4x4 spinning one tire the moment traction gets uneven. The Yukon Dura Grip YDGD44-4-30-1 is a clutch-type limited slip carrier for the standard 8.5 inch ring gear Dana 44 with 30-spline axle shafts and ring and pinion ratios of 3.92 and numerically higher, which is where most regeared trail rigs end up. It works in either a front or a rear Dana 44 that matches those specs.
Dana 44 carriers come in two ring gear mounting heights, one for 3.73 and numerically lower ratios and one for 3.92 and deeper, because the ring gear has to sit in a different spot as the pinion gets smaller. This unit is the 3.92-and-up case. Inside, clutch packs behind each side gear hold the axles to the case so torque keeps flowing to the tire that has grip, then slip enough in turns for normal street manners. Yukon builds it with a nodular iron case, forged 4320 chromoly spider gears and composite clutches, and it is fully rebuildable. The case is double drilled for both 7/16 and 1/2 inch ring gear bolts.
Read the ratio stamped on the ring gear or the axle tag: 3.92, 4.09, 4.10, 4.27, 4.56, 4.88 and deeper fit this case; 3.73 and lower need the 3.73-down carrier. Count the axle splines at the inner shaft; 30-spline shafts are about 1.31 inch diameter, while a rear with 32-spline 1.41 inch shafts needs a different unit. Our Dana 44 problems and rebuild guide covers bearing and seal wear worth fixing at the same time, and the open vs limited slip vs locker guide helps you decide if a clutch posi is the right traction aid.
Yukon's chart lists this part for 30-spline Dana 44 axles in a long run of vehicles, including 1997-2006 Jeep Wrangler TJ rear, 1986-1993 Cherokee rear, Comanche, Wagoneer, Grand Wagoneer, J10 and CJ applications, 1971-1980 International Scout II front and rear, 1971-1977 Ford Bronco front, 1980-1996 Ford Bronco and F-150 Dana 44 TTB front, 1994-2001 Dodge Ram 1500 and 1994-2002 Ram 2500 front, older Dodge W-series and Ramcharger fronts, and 1960s-1980 Chevrolet and GMC K-series fronts, plus the 1993-1997 Isuzu Rodeo rear. The JK, JL and Gladiator axles are not on that list and use different carriers. Dana 44 fronts also come in standard and reverse rotation, so match your axle tag, ratio and spline count or send us your year and VIN before ordering. Other traction choices for the same axle are the Detroit Truetrac 3.92-up rear and the ELocker4 for a 3.92-up front. Browse more carriers in our hard parts category.
Pull the axle shafts (C-clips on many rears, or the hub and stub assemblies on a front), mark and remove the bearing caps, and pry the carrier out. Transfer the ring gear with new bolts; if your gear set uses 3/8 inch bolts, Yukon says you need its YSPBLT-027 bolt kit. Press on new carrier bearings and reuse or adjust the shims to hit the Yukon chart backlash of .006-.011 inch, then torque the caps and check the pattern. The Yukon Dana 44 carrier installation kit covers bearings, shims and hardware. Fill with high-grade non-synthetic GL-5 gear oil and Yukon limited slip additive; Yukon says synthetic oil is not recommended and can cause noisy or aggressive operation. See our friction modifier dosing guide, and keep it gentle for the first few hundred miles while the clutches seat.

No. This is the 3.92-and-up case. Ratios of 3.73 and numerically lower need the 3.73-down carrier because the ring gear mounting flange is different.
No. Yukon does not list the JK, JL or Gladiator axles for this part; those use different carriers. It is listed for the TJ Wrangler rear Dana 44 and many older Jeeps.
Yes. Yukon lists many front Dana 44 applications. A clutch limited slip in the front can make steering heavier in 4WD, so most owners use it where they want traction without a full locker.
The case is double drilled for 7/16 and 1/2 inch ring gear bolts. If your gear set uses 3/8 inch bolts, Yukon says to use its YSPBLT-027 kit.
A non-synthetic GL-5 gear oil with Yukon limited slip additive. Synthetic oil is not recommended by Yukon for the Dura Grip.
New carrier bearings and shims at minimum, usually as a carrier installation kit, plus gear oil and additive. If the pinion bearings are noisy, plan a full overhaul.
