Yukon Gear High Performance Gear Set For Dana 60 in a 5.13 Ratio / Thick
A Dana 60 truck on 37 in. tires, a crawler that needs more low-speed control, or a heavy rig that tows in the mountains is where 5.13 gearing makes sense. The Yukon Gear & Axle YG D60-513T is a 5.13 ring and pinion for standard rotation Dana 60 axles, and the T at the end of the part number is the reason to pick it: it is a thick gear that bolts to the 4.10-and-down carrier you most likely already have.
A Dana 60 has a carrier break between 4.10 and 4.56. Normal 4.56-and-deeper gears mount to a different carrier with the ring gear flange set closer to the pinion, so a regear from 3.73 or 4.10 usually means buying a carrier or a new locker as well. Yukon makes this 5.13 with a thicker ring gear so the teeth land in the right place on the 4.11-and-down carrier. That keeps your factory limited slip, an existing locker or your open case in service and saves a large part of the cost of a deep regear.
Yukon lists the set with a 9.75 in. ring gear, 12 ring gear bolts and a 29-spline pinion. Standard rotation means the pinion sits below the axle centerline, as in every Dana 60 rear and in Dodge and GM Dana 60 fronts. At 5.13 the driveshaft turns 5.13 times for each wheel turn, which pulls 37s with authority and slows the truck down in low range.
Confirm the axle is a Dana 60 with standard rotation and read the current ratio from the tag; our axle ratio and code guide shows where to look. Then confirm your carrier is the 4.10-and-down type, which is the whole point of the thick set. Our Dana 60 ring and pinion buyer's guide explains the carrier break and ratio by tire size. If a 4x4 front axle is a Ford high-pinion Dana 60, it needs the matching Yukon reverse rotation 5.13 thick set so both ends match.
Yukon's fitment table for this part covers standard rotation Dana 60 axles found in Dodge and Ram 2500 and 3500 trucks (1994-2002 and earlier D and W series), Chevrolet and GMC 1-ton K30/K3500 and V30 trucks, G-series and Savana vans, Ford E-series vans and older F-250 and F-350 pickups, Jeep Wagoneer, and Mopar cars with the Dana 60 rear. Dana 60 axles were optional in many of those models, so confirm yours by tag. Send us your year and VIN if you want help. For a 4.56 build on a 4.56-and-up carrier, see the Yukon Dana 60 4.56 set; the 4.88 thick version is also listed in differential hard parts.
Because the ring gear is thicker, check that it clears the housing and that ring gear bolts seat fully before final torque. Yukon's chart lists the Dana 60 at a 0.052 in. starting pinion shim, 17-30 in-lb pinion bearing preload with new bearings, 110 ft-lb ring gear bolts and 80 ft-lb caps. Rebuild with new bearings using the USA Standard Dana 60 and 61 rear master kit or, for a front, the Yukon Dana 60 front overhaul kit. If your clutch-type limited slip is tired, now is the time for the Power Lok clutch set. Read the pattern on drive and coast sides (our setup guide shows good and bad patterns), fill with 75W-90 or 75W-140 gear oil, and break the gears in gently with an early oil change. Yukon lists 37 in. as its maximum recommended tire for the Dana 60.

The ring gear is made thicker so it fits the Dana 60 4.11-and-down carrier. You keep your existing carrier, limited slip or locker instead of buying a 4.56-and-up case.
No. This set is for the 4.10-and-down carrier. A 4.56-and-up carrier needs a standard (non-thick) 5.13 set.
No. Ford Dana 60 fronts are reverse rotation. Use a reverse rotation 5.13 thick set for that axle and this one for the standard rotation rear.
It depends on tire size. As simple math, 5.13 on 37 in. tires turns the engine about as fast as a 4.30 ratio on 31 in. tires. On smaller tires 5.13 runs high RPM at highway speed, so match ratio to tire size before ordering.
A master bearing kit, gear oil, friction modifier if you have a clutch-type limited slip, and on a 4x4 a matching 5.13 set for the other axle.
Yes. This listing is backed by a 1-year warranty.
