It serves as a practical replacement that often aligns with OE part numbers like 2-3-6041X. Best for budget-conscious builders or restoration projects where exact OE matching is desired. A potential limitation is that long-term durability data is not provided in the listing.
- Interchange OE part number 2-3-6041X
- Good for classic Ford builds and daily drivers
- Check fit if you are using TKX or non-1330 U-joint configurations
CardanMaster 3-3-2491X Chromoly Slip Yoke 31 Splines
This Chromoly slip yoke is built for 1350-series transmissions and aligns with 31-spline outputs found on C6, FMX, T170, TK600, and T56 1350 family setups. It’s a strong choice for performance-oriented builds that demand higher durability and resistance to wear. Best for high-load applications and 1350 spline requirements. A caution: limited to specific 1350-series configurations; verify your output shaft compatibility before ordering.
- Chromoly construction for durability
- Works with 1350-series outputs
- Confirm exact joint compatibility with your transmission
GLOCRORET Transmission Slip Yoke 2-3-6041X
The GLOCRORET slip yoke targets Ford C-6, T45, Tremec, and related 31-spline applications with a 1330 series U-joint. It lists compatibility across 1330-series systems and various Ford, Lincoln, and Mercury cases. Best for buyers seeking a widely compatible yoke that covers multiple transmission generations. Limitation: verify precise bearing cap and spline alignment to avoid misfit on non-standard setups.
- OE/Part Number 2-3-6041X
- Broad compatibility across 1330-series U-joints
- Check cap diameter and spline alignment for accuracy
Transmission Slip Yoke 2-3-6041X 1330 Series for Ford C-6 T45 Tremec

Buying Guide: 31 Spline Slip Yoke Essentials
What is a slip yoke and why 31 splines?
A slip yoke is a driveshaft component that slides to accommodate changes in distance between the transmission output and the driveshaft. A 31-spline output provides a higher torque capacity and better engagement in many Ford/C6 and Tremec setups, compared with some lower-count options. Always match spline count and yoke type to your transmission output shaft and driveshaft U-joint size.
Key compatibility checks
- Confirm transmission model and OE part numbers (e.g., 2-3-6041X references) to ensure proper fit.
- Verify spline count at the output shaft and the inside yoke to avoid misfit.
- Check U-joint compatibility (1330 vs 1350 series) and bearing cap dimensions for a tight installation.
Material and durability considerations
Chromoly or forged steel slip yokes provide superior strength for high-load or high-performance builds. For daily driving, a standard steel yoke with proper heat treatment may suffice. Consider the environment and load profile when choosing a material.
Installation notes
- Ensure correct torque specs for bolts attaching the yoke to the transmission output shaft.
- Inspect the driveshaft slip mechanism for smooth operation and absence of burrs or misalignment.
- When in doubt, refer to the vehicle’s service manual or a professional technician for alignment and balancing checks after installation.
Best-for-Need quick-reference
Choose this if you need a reliable direct replacement for Ford C6 or T45 with 31-spline outputs. Pick a 1330-series yoke when your driveshaft uses 1330 U-joint hardware; select 1350-series considerations for heavier-duty Tremec setups. If you’re on a tighter budget but still want solid compatibility, the JAVOUKA option offers a practical balance between cost and function.
FAQ
- What does 31 spline mean? It refers to the number of teeth on the output shaft engaging the yoke, affecting strength and fit.
- Can I use a 1330-series yoke with a 1350 driveshaft? No. Use matching joint-series for proper fit and longevity.
- Is a chromoly yoke necessary for daily driving? Not always, but it’s beneficial for high-load or performance use.
- How do I verify compatibility with my transmission? Check the OE part number, spline count, and the joint-series (1330 vs 1350) listed by the seller.
- Should I upgrade just the yoke or the entire driveshaft? If the existing driveshaft is worn or out of balance, upgrading the yoke alone is often insufficient; assess the driveshaft condition as well.
- Are there any fitment risks? Mismatched spline sizes or non-standard bearing caps can cause misfit or damage; always measure and confirm before purchase.
