1480 Forged U-Bolt Pinion Yoke for Dana 80 - 37 Spline
3-4-11171
The 1480 Forged U-Bolt Pinion Yoke for Dana 80 is a heavy-duty driveline upgrade for Dana 80 axles using a 37-spline pinion and 1480 series U-joint. Its forged construction and large 1480 joint configuration are built for the torque and driveline shock found in rock bouncers, rock crawlers, large-tire buggies, high-horsepower builds, and other demanding off-road applications.
The U-bolt retention design also makes the driveline easier to service when something goes wrong. Instead of the small retaining bolts used with traditional strap-style yokes, the U-bolts can be removed and replaced without dealing with broken or seized strap bolts—giving high-load Dana 80 builds a strong, straightforward driveline connection that is easier to repair on the trail.
Includes:
- (1) 1480 Forged U-Bolt Pinion Yoke
- (2) U-Bolts
- U-Bolt Nuts & Lock Washers

Fitment
Designed For:
- Dana 80 axle applications
- 37-spline pinion shafts
- 1480 series driveshaft U-joints
- Heavy-duty off-road driveline builds
- Custom Dana 80 axle assemblies
Fitment Notes:
- Requires a compatible Dana 80 37-spline pinion shaft.
- Designed for a 1480 series U-joint with a 4.188" retaining width and 1.375" bearing cap diameter.
- Uses U-bolt retention rather than conventional U-joint straps.
- Verify axle model, pinion spline count, and driveshaft U-joint series before ordering.
- Maximum joint angle is listed at 30°; actual operating angle depends on the complete driveshaft, suspension, and axle configuration.
FAQ
What Dana 80 does this pinion yoke fit?
This yoke is designed for compatible Dana 80 axle applications using a 37-spline pinion shaft. Verify the axle and pinion spline count before ordering.
What size U-joint does this Dana 80 yoke use?
This yoke is designed for a 1480 series U-joint with a 4.188" retaining width and 1.375" bearing cap diameter.
Why use a 1480 U-joint on a Dana 80?
A 1480 series U-joint provides a large driveline connection suited to the torque loads commonly associated with Dana 80 axle builds. It is a strong choice for large tires, low gearing, high-horsepower engines, and aggressive off-road applications.
Why use a U-bolt yoke instead of a strap-style yoke?
A U-bolt yoke captures the U-joint bearing caps with two U-bolts instead of small straps and retaining bolts. This eliminates the small strap bolts that can become damaged, seized, or broken and makes U-joint service more straightforward in an off-road application.
Will this yoke work with my existing driveshaft?
It will work when the driveshaft uses a compatible 1480 series U-joint and the Dana 80 uses the correct 37-spline pinion. If your driveshaft uses a different U-joint series, the driveshaft or U-joint configuration may need to be changed.
