Overview
The Dana Spicer 5-212X is a forged, lubeable crossover U-joint that links a 1330 series yoke to a GM 3R series yoke, as its title states. Crossover joints like this one are used where a driveshaft has to join two different yoke styles, so the cup and snap ring measurements must suit both ends.
It is a universal fit crossover, so the 1330 and GM 3R yoke sizes decide whether it suits a driveline. Confirm fit for your vehicle’s year, model and trim before ordering.
Key features
- Crossover design for 1330 to GM 3R conversions
- Forged cross
- Lubeable, so it can be greased during service
- Cup size A of 1.062in and cup size B of 1.1250in
- Outside to outside A of 3.625in
Before you buy
A crossover U-joint sits where a driveshaft changes yoke style, so it carries the load from one end of the driveline to the other while the two ends run at different angles. Choosing one starts with measuring both yokes. Compare the cup dimensions and the snap ring spacing at each end, and make sure the joint matches the yoke it will meet on each side rather than relying on a general series name.
Crossovers are often replaced in pairs with the rest of the shaft’s U-joints, especially when the old joints show play or dry bearings. Check for wear by lifting the shaft and feeling for movement at each cross, and look for rust or grease leakage around the cups. A worn crossover can cause vibration that is easy to mistake for a problem elsewhere in the driveline.

Vehicle fitment
No vehicle, year or model is named for this crossover, so fitment is not confirmed for any Jeep or truck. Match the joint to your driveline by its 1330 and GM 3R yoke ends and the cup dimensions above.
Joints for other series are separate parts and fall outside this 1330 to GM 3R crossover. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
Measure both yokes before fitting, since the cup sizes and snap ring to snap ring distance must match the ends being joined. Grease the lubeable cross after assembly and check driveline angles once the shaft is back in place.
What’s included
The joint is a single crossover. Check the package contents against your installation before starting, including snap rings and grease.
