Yukon Gear 4340 Chrome-Moly Replacement Inner Axle For Dana 60 / 80-86 GM Chevy 1 Ton / 79-90 Dodge
Running 40-inch tires and a locker on a square-body Chevy K30 or a Dodge W-series one-ton puts the front Dana 60 inner shafts in the line of fire. Yukon Gear and Axle YA W48210 is the driver-side inner front shaft for the Dana 60, made from 4340 chromoly with 35 splines and an overall length of 35.10 inches. It is the part to buy when the left inner has snapped at the spline, twisted, or worn its splines loose in the side gear.
A solid front axle splits each side into two shafts. The inner shaft runs from the side gear in the carrier out through the axle tube to the inner yoke of the steering U-joint; the outer stub runs from that U-joint through the spindle to the hub. On these kingpin-era GM and Dodge one-ton fronts, the inner shaft takes full torque whenever the hubs are locked, and with a locker or spool it takes it no matter which tire has grip. Yukon builds this shaft from 4340 chromoly with cold roll formed splines and induction heat treating. Chromoly tends to twist visibly before it lets go, where a factory induction-hardened shaft usually snaps clean.
With the front on stands, the hubs locked and the transfer case in 4WD, turn the left wheel by hand; if it spins while the front driveshaft stays still, the shaft or U-joint is broken. Pull the hub, spindle and shaft assembly and inspect the inner splines and the U-joint yoke. Count the splines at the carrier end: this shaft is 35 spline, and the Dana 60 has been built with several inner spline counts, so the side gear must match. Measure the old shaft too. For kingpin, hub and bearing faults that feel similar, see our Dana 60 front axle problems and rebuild cost guide, and chromoly axle shafts vs stock explains when the upgrade pays off.
Yukon's fitment table lists this left inner for the front Dana 60 in 1979-1986 Chevrolet K30, 1987-1988 Chevrolet V30, 1979-1986 GMC K3500, 1987 GMC V3500, 1976-1980 Dodge W300, and 1981-1993 Dodge W250 and W350. Our listing title names 1980-1986 GM and 1979-1990 Dodge, so go by the table, and remember these years ran several Dana 60 versions and spline counts. Not every 3/4-ton in those years got a Dana 60, so check the axle tag first. Match spline count (35) and length (35.10 inches), or send us the year and VIN. Other heavy axle parts are in our hard parts category.

YA W48210 is the left-hand inner front shaft, the driver side on a US-market truck.
No. It is the inner shaft only, from the carrier to the inner U-joint yoke. Reuse or replace your outer stub and U-joint separately.
Only if the carrier side gears are 35 spline. Front Dana 60s were built with several inner spline counts, so count the splines on your old shaft before ordering.
The title names 1980-1986 GM and 1979-1990 Dodge. Yukon's table lists 1979-1986 K30/K3500, 1987-1988 V30, 1987 V3500, 1976-1980 W300 and 1981-1993 W250/W350. Go by the table and confirm with your axle tag or VIN.
If you run a locker or big tires, yes. 4340 chromoly is tougher than a factory shaft and tends to twist before it breaks, which often gets the truck home.
