Keller CFMOTO UForce U10 Pro Ball Joints replace the factory upper and lower ball joints with a threaded two-piece 4340 chromoly design that eliminates the OEM snap ring. One side presses in and the other threads on like a nut and bolt, which makes them virtually impossible to pull out on the 2025+ U10 Pro and U10 Pro XL.
Hardened chromoly housings and studs, a robust boot retaining ring to keep water out, and an adjustable, rebuildable, greaseable design keep them running longer than stock. Order upper, lower or both, in single, two or four-joint quantities. They install as easily as stock and carry a lifetime warranty.

FAQ
What OEM part numbers do these replace?
They replace OEM 9030-050600-10000 (upper) and 9060-050900-10000 (lower).
Why is there no snap ring?
Keller's two-piece design threads onto the A-arm like a nut and bolt, so a snap ring is not needed and the joint is virtually impossible to pull out.
Can I grease them?
Yes. They are greaseable, adjustable and rebuildable.
How many do I need for a full set?
The U10 Pro uses upper and lower joints on each side; the four-joint option covers the full front set.
Do they fit the U10 Pro XL?
Yes. The U10 Pro XL and U10 Pro XL Highland (2025+) are listed.
Are they harder to install than stock?
Keller says the two-piece design is just as easy to install as stock.
