Transmission Slip Yoke 1310 Series & U-Joint Kit (GM TH/TH350/700R4)
This kit covers 1310 series slip yokes with 26/27 splines. It is designed for GM TH, Turbo Hydromatic, TH350, Powerglide, 700R/700R4, 4L60/4L60E, Saginaw and Muncie/Borg Warner configurations. The kit includes U-Joint components to help transmit power smoothly and reduce vibration. Best for buyers upgrading classic GM rear-drive trucks and muscle cars that use 1310-series joints.
Who it’s best for: Classic GM drivers needing a reliable 1310-series slip yoke replacement with compatible 26/27 spline U-joint hardware. Why selected: Wide compatibility with common GM transmissions and a complete U-Joint kit for straightforward installation.
Caution: Verify spline compatibility (26/27) and ensure your drive shaft length matches 5.469 inches overall length before purchase.
JAVOUKA Slip Yoke U-Joint Kit 2-3-6081X, 5-153X (1310 Series)
This 1310-series kit is built for GM Turbo Hydramatic family, including TH350, Powerglide, and 700R variations, with 26 spline inside and 27 spline trans outputs. It also lists compatibility with several Jeep models and Muncie/Borg Warner transmissions. The included U-Joint components aim to minimize vibration and wear while improving driving stability.
Who it’s best for: Off-road and street GM owners seeking broad compatibility and an OE-number cross-reference (2-3-6081X, 5-153X). Why selected: Strong alignment with common GM and Jeep transfer points, offering a versatile option for mixed-driver fleets.
Caution: Check the exact spline arrangement and vehicle year range to ensure fitment with your transmission and driveshaft configuration.
JAVOUKA Slip Yoke 2-3-6041X (1330 Series)
This slip yoke targets 1330-series driveline components with a 31-spline output and a 30-spline inside yoke configuration. It is designed for Ford C-6 transmissions, T45, FMX, and related gearboxes. The kit is identified as an OE-part alternative and is suitable for Ford-based vehicles that share the same slip yoke geometry.
Who it’s best for: Ford/C-6 and similar transmissions requiring 1330-series compatibility. Why selected: Clear 1330-series alignment for non-GM applications, broadening the kit’s use in mixed fleets.
Caution: Confirm the spline counts and inside/outside yoke dimensions before ordering to avoid misfit with your payload shaft.
GLOCRORET Drive Shaft Slip Yoke 2-3-10431X (1310 Series)
This option corresponds to the 1310-series U-Joint with 5-153X compatibility and addresses GM Turbo 400 TH400, Muncie/M20/M21/M22, 4L80E/4L85E, and related units. It supports a broad range of high-torque transmissions and is geared toward stability in performance-focused applications.
Who it’s best for: Users with GM Turbo 400/4L80E family drives seeking a 1310-series yoke with strong endurance. Why selected: Notable support for multiple transmissions and the M-spline family for robust power transfer.
Caution: The listed fitment may vary across model years; confirm your system’s U-Joint size and tailshaft configuration before purchase.
Cardanmaster 3-3-5551X Transmission Slip Yoke (32 Splines)
This 1350-series slip yoke features 32 splines and is intended for GM 4L80E, TH400, NP 205, NP 263 transfer cases and related 1998–2007 GM magnum variants. It also suits certain transfer-case setups and heavy-duty transmissions, offering a larger spline footprint for higher torque.
Who it’s best for: Vehicles requiring a 1350-series yoke with 32 splines, including heavier transfer-case configurations. Why selected: Clear compatibility with 4L80E/TH400 and NP transfer case platforms, providing a robust option for high-load driveshafts.
Caution: Ensure alignment with your transfer case and tailshaft length, as 1350-series yokes are larger than 1310/1330 counterparts.
Buying Guide
Key considerations when choosing a slip yoke and U-Joint kit:
- Spline series and count: Match 1310, 1330, or 1350 splines to your transmission output and driveshaft input for proper engagement.
- Yoke dimensions: Confirm outside yoke diameter, bearing cap diameter, and overall length to fit your tailshaft and seal area.
- Vehicle application: Identify your transmission family (TH, TH350, TH400, 700R4, 4L60/4L60E) and transfer-case compatibility.
- U-Joint compatibility: Ensure included U-Joint components are compatible with your existing joints and cross-style assemblies.
- Installation context: Consider whether you need an OE-part substitute or a broader, cross-brand option for mixed fleets.
- Durability and vibration: Look for kits designed to minimize wear and reduce drive-line vibrations in high-torque applications.
Frequently Asked Questions
- Q: What spline count should I choose for a GM TH400 with a 1310 yoke?
A: A 1310-series yoke typically uses 26/27 splines; verify your transmission output and driveshaft spline alignment. - Q: Are these slip yokes interchangeable with Jeep applications?
A: Some kits reference Jeep compatibility in their description; confirm spline count and yoke dimensions before cross-use. - Q: How do I confirm if my yoke is 1330 or 1350-series?
A: Check the spline count (1330 often 31 splines inside; 1350 often 32 splines) and the overall yoke size (outside diameter and length). - Q: Can I replace just the U-Joint or should I replace the whole slip yoke?
A: If the yoke is worn, replacing the slip yoke with the U-Joint kit is common practice; for damaged seats or bearing surfaces, replacing the entire assembly may be necessary. - Q: Do these kits affect driveline vibrations?
A: Yes, properly matched yoke and U-Joint kits can reduce vibration by ensuring proper alignment and torque transfer. - Q: Is a longer yoke always better?
A: Not necessarily; length must match your driveshaft and tailshaft geometry to avoid contact or misalignment.
