Yukon Gear Dana 60 4.10 & Down Dura Grip Positraction Narrow 32 Spline ABS Compatible

Two very different trucks share this part: the 2000-2002 Dodge Ram 2500 and 3500 4x4, whose Dana 60 front went to 32-spline shafts for those years, and Ford E-350 vans and wagons with a 32-spline full-float Dana 60 rear. Both leave a tire spinning when the open carrier unloads one side, whether that is a loaded van on a wet boat ramp or a Ram in snow. The Yukon Dura Grip YDGD60-3-32 is a clutch-type positraction for those 32-spline Dana 60s, cut for the 4.10-and-down carrier, also fits thick deep gears, and is listed as ABS compatible.

What the Dura Grip does in a 32-spline Dana 60

The Dura Grip keeps conventional spider gears, four of them in forged 4320 chromoly, inside a nodular iron case. Composite clutch packs sit behind each side gear under spring preload. When both tires grip, the clutches let them turn at slightly different speeds in a corner. When one side starts to slip, the clutch packs resist the speed difference and send torque across to the side with traction. Unlike a locker, it never fully locks, so it stays quiet and predictable on pavement, which suits a work van or a daily driven Ram. Yukon calls it fully rebuildable, so the clutches can be refreshed later rather than replacing the whole case.

Symptoms that point to this unit

• One rear tire spins on a loaded E-350 pulling away on gravel, wet grass or ice
• A Ram front that spins one tire in 4WD with the axle disconnect engaged
• An old factory limited slip that has lost its bite or chatters
• Worn spider gears or a sloppy open carrier found during a bearing or gear job

How to confirm before buying

Spline count is the big one: Dana 60 shafts come in 30, 32 and 35 splines, and only 32 fits this case. Pull a shaft and count. Then check the ratio on the axle tag or ring gear. Yukon lists this unit for 4.10 and down or thick gears; its Ram front notes read 4.30 and down or thick gears. Gears from the 4.56-up series take a different carrier, explained in our carrier break guide. If you are choosing between a posi, a helical unit and a locker, see open vs limited slip vs locker.

Fitment

Yukon's application list: 2000-2002 Dodge Ram 2500 and Ram 3500 4WD with the disconnect-design Dana 60 front, and Ford E-350 Econoline, Club Wagon and E-350 Super Duty with the full-float 32-spline Dana 60 rear, roughly 1995-2008 depending on model. Yukon notes it fits front and full-float rear applications. The part name also says Narrow; because a few Dana 60 carrier versions exist, match your spline count, ratio and axle tag, or send us your year and VIN before ordering. For a 35-spline axle look at the Grizzly Locker 35-spline or the ELocker4 35-spline. More axle parts are in hard parts.

Install notes

• Do bearings at the same time with the Dana 60 front master overhaul kit for a Ram, or the rear kit for an E-350.
• Spread the housing to remove and set the carrier; Dana 60 carrier preload comes from shims.
• Yukon's Dana 60 setup chart: 17-30 in-lb new pinion preload, 110 ft-lb ring gear bolts, 80 ft-lb caps.
• Yukon recommends a high grade non-synthetic GL-5 gear oil plus two bottles of Yukon LSD additive, and says synthetic may cause aggressive or noisy operation. Our friction modifier guide covers dosing.
• Drive gently for the first few hundred miles while the clutches and new gears bed in.

Does YDGD60-3-32 fit my 1999 Ram 2500 front?

Yukon lists the 2000-2002 Ram 2500 and 3500 fronts. Earlier second-generation Ram Dana 60 fronts generally used 30-spline shafts, so count the splines on your axle before ordering.

Will it fit a Dana 60 with 4.56 gears?

Only with thick gears built for the 4.10-and-down carrier. Standard 4.56-and-up gear sets need the other carrier series.

What does ABS compatible mean here?

Yukon lists this Dura Grip as ABS compatible, meaning it is intended for Dana 60 applications whose trucks have anti-lock brakes. As with any carrier swap, make sure any wheel speed sensor and tone ring on your axle are reinstalled undamaged.

What gear oil and additive does it need?

Yukon recommends high grade non-synthetic GL-5 gear oil plus two bottles of Yukon LSD additive. Synthetic oil is not recommended and may cause aggressive or noisy operation.

Can it be rebuilt later?

Yes. Yukon describes the Dura Grip as fully rebuildable, so worn clutches can be replaced without buying a new case.

What should I replace with it?

Carrier and pinion bearings, the pinion seal, new ring gear bolts and fresh fluid. A Dana 60 master overhaul kit covers the bearings and seals.
