1480 Forged U-Bolt Pinion Yoke for GM 14-Bolt & AAM - 30 Spline
00107
The 1480 Forged U-Bolt Pinion Yoke for GM 14-Bolt & AAM Axles is a heavy-duty driveline upgrade for compatible GM 10.5" 14-Bolt, AAM 10.5", and AAM 11.5" axles using a 30-spline pinion and 1480 series U-joint. The forged construction and larger 1480 joint configuration make it a strong choice for rock bouncers, rock crawlers, high-horsepower buggies, large-tire builds, and other applications that put serious torque and shock load through the driveline.
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 off-road builds a strong, straightforward 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:
- GM 10.5" 14-Bolt axles
- AAM 10.5" axles
- AAM 11.5" axles
- Compatible 30-spline pinion shafts
- 1480 series driveshaft U-joints
- Heavy-duty and high-performance off-road driveline builds
Fitment Notes:
- Requires a compatible 30-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 26°; actual operating angle depends on the complete driveshaft, suspension, and axle configuration.
FAQ
What axles does this 1480 pinion yoke fit?
This yoke is designed for compatible GM 10.5" 14-Bolt, AAM 10.5", and AAM 11.5" axle applications using a 30-spline pinion shaft. Verify your axle and pinion spline count before ordering.
What size U-joint does this 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 instead of a 1350?
A 1480 series U-joint is physically larger than a 1350 and is commonly used when the driveline needs to handle increased torque and shock loading. It is a strong choice for large tires, low gearing, high-horsepower engines, and aggressive off-road use.
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 axle uses the correct 30-spline pinion. If your current driveshaft uses a different U-joint series, the driveshaft or U-joint configuration may need to be changed.
