Description
When your driveline combines a standard 1310 series yoke with a 2R series yoke requiring inside clip retention, you need a combination U-joint that speaks both languages. This 1310 to 2R conversion joint eliminates the need for adapter yokes or driveshaft modifications by incorporating both series dimensions into a single precision-machined cross.
The 1310 side features the standard 3.25" width and 1.062" cap diameter used across countless muscle car, street rod, and light truck applications. The 2R side delivers 2.344" inside lock-to-lock measurement with 1.00" caps designed for yokes machined with internal snap ring grooves rather than external retention. Inside lock U-joints are measured differently than outside lock types--from the grooves in the caps where the C-clips seat, not the overall cap width.
Built with a solid steel, non-greaseable body, this combination joint delivers enhanced durability over greaseable designs while eliminating maintenance intervals. The needle bearing construction provides smooth operation under load, transferring power reliably through mismatched yoke configurations. All required snap rings are included for both the outside lock 1310 side and inside lock 2R side, so you're ready to install right out of the box.
Ideal for custom driveshaft builds, transmission swaps, or rear end conversions where mixing U-joint series is unavoidable. Made in the USA with precision manufacturing for dependable performance.
