vierzweites 1310-Series Transmission Slip Yoke & U-Joint Kit — 26/27 Spline, 5.469" Length

This complete kit combines a precision-machined 1310-series slip yoke with matched universal-joint components to replace part numbers 2-3-6081X and 5-153X. It’s built for a tight fit, consistent spline engagement, and direct installation without modifications. The kit targets transmissions used in a wide range of vehicles — from Turbo Hydramatic and Powerglide to 700R/4L60 families and classic Saginaw and Muncie gearboxes.

What transmission models does this kit fit?

The kit is designed for many common automatic and manual transmissions, covering popular GM and classic platforms. It fits 1310-series applications and is intended as a drop-in replacement for several legacy part numbers.

• Compatible with Turbo Hydramatic, Turbo 350, Powerglide and 700R/700R4 families
• Works with 4L60 and 4L60E electronic automatics
• Also fits Saginaw 3- and 4-speed, Muncie 4-speed, and BorgWarner T-4/T-5/T-10
• Replaces OEM references 2-3-6081X and 5-153X

How precise are the components and what are the key dimensions?

Components are machined to tight tolerances to ensure proper sealing, spline engagement, and long-term reliability. Exact dimensions help you confirm fitment before installation.

• Spline type: 26 or 27 spline options for 1310-series compatibility
• Slip yoke overall length: 5.469 inches
• Outside yoke dimension: 3.469 inches; hub diameter: 1.500 inches
• Bearing cap diameter: 1.062 inches for matched U-joint fit

What’s included and how does the u-joint improve drivability?

The kit supplies both the slip yoke and the U-joint connection hardware so the driveshaft links correctly with the transmission tailshaft. A properly matched U-joint reduces vibration, limits premature wear, and helps maintain smooth torque transfer during acceleration and cruising.

• Complete U-joint assembly sized for the supplied yoke
• Hardware pre-fit to factory specifications to prevent loosening
• Design reduces driveline vibration and uneven wear on bearings
• Tested for immediate, tool-ready installation—no rework required

Will this part require modification or extra parts to install?

vierzweites engineers the kit to meet original factory dimensions so it installs without special machining in most cases. That said, always compare your vehicle’s current part measurements and spline count to ensure exact compatibility.

• Factory-spec machining for direct fit on compatible transmissions
• No additional modification expected for standard 1310-series setups
• Verify spline count (26 or 27) and shaft measurements before purchase
• Installation hardware included where applicable to speed fitment

Who is this for: This kit is ideal for mechanics, restorers, and enthusiasts replacing worn or damaged slip yokes and U-joints on GM automatics (including Turbo Hydramatic and 700R/4L60 families) and classic manual boxes like Saginaw and Muncie. Choose this assembly if you need a precision, ready-to-install 1310-series replacement that matches OEM geometry and helps reduce driveline vibration while restoring reliable shaft engagement.
