Factory Steering Box U-Joint – 1” DD to 3/4”-36 (Satin Finish)
Confirmed Fitment with 1967-72 and 1973-79 Fat Fender Garage Column Kits with a Factory Steering Box
This slim-profile, needle-bearing universal joint from Flaming River is the exact part we recommend when connecting our 1967–72 or 1973-79 F100 steering columns to the factory steering box. It’s compact, smooth, and built to last — the same part we trust in our own builds.
Crafted from high-strength chrome moly and featuring sealed needle bearings, it offers a tighter, smoother steering feel than old-school pin and block joints — with zero maintenance required. The low-profile design makes it ideal for tight engine bays and clean installs.
⚠️ Heads up: This U-joint is only for use with the factory steering box. If you’re running an aftermarket power steering rack (like Mustang II or rack-and-pinion setups), you'll need a different joint based on your rack’s input shaft. Reach out to us — we can help you get the right one.
