Yukon Gear High Performance Gear Set For Dana 60 Reverse Rotation in a 3.54 Ratio
A high-pinion Dana 60 front that whines on the highway in two-wheel drive, or a Ford Super Duty or swap axle that has to be matched to a 3.54 rear, needs a reverse rotation gear set. Standard Dana 60 rear gears will not do the job. This Yukon Gear & Axle set, part number YG D60R-354R, is a 3.54 ratio ring and pinion cut for reverse rotation Dana 60 axles, with a 9.75 in. ring gear, a 29-spline pinion and 12 ring gear bolts.
In a high-pinion front axle the pinion enters the housing above the axle centerline. That keeps the front driveshaft up and out of the rocks, but it means the ring gear is driven from the opposite side compared with a rear axle. Gear teeth are designed to carry load on one face, the drive side, and a reverse cut set puts that strong face where a front axle actually pushes. Drop a standard rotation set into a high-pinion housing and it runs on the thinner coast side every time you are in four-wheel drive, which is how cheap swaps end up with chipped teeth.
At 3.54 the pinion turns 3.54 times for each turn of the ring gear. That is one of the taller ratios offered for this axle, so it suits a truck on near-stock tire sizes, a gas or diesel rig that spends most of its life on the highway, or a build where the rear axle is already set at 3.54 and the front has to match it exactly.
Start by proving the axle really is reverse rotation: look at where the front driveshaft enters the housing. Above the axle tubes means high pinion. Then find the current ratio from the axle tag or by counting ring and pinion teeth, and check the rear axle so both ends end up identical. Our hard parts section carries the rest of the Dana 60 parts. If the gears look clean and only the bearings are worn, a master install kit alone may fix the noise; if teeth are damaged, replace the set.
Yukon lists this set for the reverse rotation Dana Spicer 60 with a 9.75 in. ring gear, 29-spline pinion and 12 ring gear bolts. The best-known example is the 1999-2016 Ford Super Duty F-250 and F-350 front axle, and high-pinion Dana 60s also turn up in aftermarket and swap builds. The 2017-and-later Super Duty front is a newer short-pinion design that takes its own gears, so this set is not for it. A 3.54 ring gear mounts on the 4.10-and-down Dana 60 carrier, so if your truck already runs 3.54 to 4.10 your existing carrier works; coming from a 4.56-or-deeper axle means you also need a 4.10-and-down carrier. Confirm rotation, tooth count and carrier series, or send your year and VIN and we will check it.
New gears always get new bearings. For a 1999-2016 Super Duty front, the Super Duty Dana 60 front master kit includes the crush sleeve style parts that axle uses. Set pinion depth first; a pinion depth setting tool gets the first trial assembly close. Yukon's set-up chart for the Dana 60 lists 17-30 in-lb of preload on new pinion bearings, about 0.006-0.011 in. backlash, 110 ft-lb on the ring gear bolts and 80 ft-lb on the bearing caps. Read the drive and coast pattern on both sides of the teeth before final torque.
Fill with 75W-90 or 75W-140 GL-5. Yukon's break-in rules are the same for a front axle: drive lightly for the first 15-20 miles and let it cool, avoid hard acceleration for 100 miles, wait 500 miles before towing, and change the oil at 500 miles. If you are building a deeper front instead, compare this with the reverse rotation 5.13 set.

The 1999-2016 Super Duty front is a reverse rotation Dana 60, which is what this set is cut for. Match the ratio to your rear axle and confirm the tooth count on your tag before ordering, or send your VIN and we will check it.
No. The 2017-and-later front axle is a short-pinion reverse design that uses its own gear sets.
Only if your current carrier is the 4.56-and-up series. A 3.54 ring gear bolts to the 4.10-and-down Dana 60 carrier.
No. Standard rotation gears in a high-pinion axle load the weak coast side of the teeth and wear quickly. Use a reverse cut set like this one.
Use 75W-90 or 75W-140 GL-5. Drive gently for the first 15-20 miles, avoid hard acceleration for 100 miles, do not tow for 500 miles, then change the oil.
