1410 Forged U-Bolt Pinion Yoke for GM 14-Bolt - 30 Spline
3-4-8001X
The 1410 Forged U-Bolt Pinion Yoke for GM 14-Bolt is a heavy-duty driveline upgrade for GM 14-Bolt 10.5" and compatible 11.5" axle applications using a 30-spline pinion and 1410 series U-joint. Forged construction provides the strength needed for rock crawlers, rock bouncers, trail rigs, high-horsepower builds, towing applications, and other vehicles that place increased 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—providing a strong, serviceable connection for builds where driveline durability and trail-side repairability matter.
Includes:
- (1) 1410 Forged U-Bolt Pinion Yoke
- (2) U-Bolts
- U-Bolt Nuts & Lock Washers

Fitment
Designed For:
- GM 14-Bolt 10.5" axle applications
- Compatible GM 11.5" axle applications
- 30-spline pinion shafts
- 1410 series driveshaft U-joints
- Heavy-duty and performance off-road driveline builds
Fitment Notes:
- Requires a compatible 30-spline pinion shaft.
- Designed for a 1410 series U-joint with a 4.188" retaining width and 1.188" 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 GM 14-Bolt does this pinion yoke fit?
This yoke is designed for GM 14-Bolt 10.5" and compatible 11.5" axle applications using a 30-spline pinion shaft. Verify your specific axle and pinion spline count before ordering.
What size U-joint does this yoke use?
This pinion yoke is designed for a 1410 series U-joint with a 4.188" retaining width and 1.188" bearing cap diameter.
Why use a 1410 U-joint on a GM 14-Bolt?
A 1410 series U-joint provides a heavy-duty driveline connection for builds running large tires, low gearing, increased engine power, and other combinations that place higher torque and shock loads through the axle and driveshaft.
Why use a U-bolt yoke instead of a strap-style yoke?
A U-bolt yoke captures the U-joint bearing caps with U-bolts rather than small straps and retaining bolts. This removes the small strap bolts that can become seized or broken and makes U-joint service easier in demanding off-road applications.
Will this yoke work with my existing driveshaft?
It will work when the driveshaft uses a compatible 1410 series U-joint and the axle uses the correct 30-spline pinion. If your existing driveshaft uses a different U-joint series, the driveshaft or U-joint configuration may need to be changed.
