Overview
The Dana Spicer 1310 Series pinion yoke, part number 2-4-3801-1X, is a strap style pinion yoke for Dana 60, Dana 61 and Dana 70 axles. It is designed as a replacement for the stock yoke, so it can repair a worn one or upgrade the pinion connection.
Dana Spicer makes the yoke for front and rear axle locations. Used yokes are often worn, and a new yoke avoids hunting through salvage yards for one that is still sound. No vehicle is named for this yoke, so confirm the axle type before fitting.
Key features
- Strap style yoke with a 1310 Series U-joint
- Designed as a replacement for the stock yoke
- It is made for Dana 60, Dana 61 and Dana 70 axle types.
- Available for front and rear axle locations
Before pulling the old yoke
A pinion yoke takes the driveshaft’s torque into the pinion, so its condition affects every joint on the driveline. Before removal, mark the pinion and yoke positions, photograph the strap hardware and note how the old yoke sits against the seal. Those steps make reassembly easier and help you spot damage that a replacement would not fix.
Worn yokes often show play where the U-joint caps seat, grooves on the bearing surfaces, or a clunk when torque reverses. Fitting a new yoke without checking the pinion and seal can push the same wear into the new part, so inspect them while the axle is open.
- Check the strap hardware for stretched or cracked straps
- Look for seal wear where the yoke contacts the seal lip
- Replace the U-joint when you replace the yoke

Vehicle fitment
No vehicle is named for this yoke. It matches by axle type and U-joint series: Dana 60, Dana 61 or Dana 70 axles with a 1310 Series joint.
Other axle types and joint series than those above do not match this yoke. Confirm fit for your vehicle’s year, model and trim before ordering.
Installation notes
Strap style yokes attach with straps rather than U-bolts, so check the strap hardware before removing the old yoke. Pinion bearing preload is set during reassembly, and a driveline shop with a preload gauge is the practical route.
What’s included
The yoke is the only item this part covers. Check the package contents against your installation before starting.
