2-3-9991X Slip Yoke 1210 Series, Splines: 1.219X26/28, Centerline To End: 5.109 Inch

The 2-3-9991X Slip Yoke is a critical component for any driveline setup utilizing the 1210 Series. This yoke connects the driveshaft to the transmission or transfer case, allowing for necessary axial movement during suspension travel. With a spline diameter of 1.219 inches and a unique 26/28 spline count, this slip yoke is engineered to deliver reliable performance under demanding conditions.

What sets the 2-3-9991X apart from other slip yokes is its specific spline configuration. While it may look similar to other yokes, the 1210 Series designation ensures compatibility with the correct U-joint size and cross width. Using a yoke that doesn’t match these specifications can lead to improper fitment and potential driveline failure.

When installing the 2-3-9991X, keep these key points in mind:

• Verify spline engagement depth to ensure a secure fit.
• Check phasing with the opposite yoke to maintain driveline balance.
• Do not force spline entry; ensure proper alignment.
• Measure the center U joint to end length of 5.109 inches for accurate fitment.

In summary, the 2-3-9991X Slip Yoke is designed for seamless integration into your driveline system, ensuring smooth power transfer and durability. Always match the specifications closely to avoid issues down the line.
