Kawasaki Teryx KRX 1000 ball joints fail at the snap ring, not the joint itself. That thin clip is the only thing holding a factory joint in the A-arm, and the KRX is a heavy car with long travel that lands hard — exactly the load case that deforms or shears it. Keller ball joints remove it entirely — the two-piece housing threads into the arm like a nut and bolt. Hardened 4340 chromoly, greaseable, adjustable and rebuildable.
Todd Keller's original threaded design, covering the KRX 1000 from 2020 and the four-seat KRX 4 1000 from 2023. Sold as a single joint — set the quantity you need at checkout.

Built To Solve: Teryx KRX Ball Joint Pull-Out and Snap Ring Failure
- Snap ring shearing and letting the joint separate from the A-arm
- Clunking or knocking from the front end over rough ground and whoops
- Play in the wheel when rocked top-to-bottom on a jack
- Repeat OEM joint failures on a heavy long-travel car that lands hard
- Torn boots admitting water, mud and grit so the joint wears from the inside
- Replacing the same joint often enough that it has become routine maintenance
Best For: Hard-Ridden Teryx KRX Builds
- KRX 1000 and KRX 4 1000 owners riding desert, dunes and rock
- Riders landing a heavy car front-first
- Owners running larger tires or added lift
- KRX 4 owners carrying more weight through the front end
- Anyone who has already replaced a factory joint more than once
The standard Teryx 750, 800 and S use a different Keller joint and have their own listing.

FAQ
Why do Teryx KRX ball joints pull out of the A-arm?
The factory joint is retained by a snap ring seated in a groove. The KRX is heavy and travels a long way, and landings can deform or shear that ring — once it goes the joint has nothing holding it. Keller joints thread into the A-arm instead, so there is no clip to fail.
How many do I need?
This listing is a single joint, so set the quantity yourself: one for a single failure, or four for a complete front end. Most riders replacing joints on a high-hour KRX do all four at once.
Will these fit my standard Teryx?
No. The KRX uses a different Keller joint from the Teryx 750, 800 and S — order from the standard Teryx listing for those machines.
Do these fit the four-seat KRX 4 1000?
Yes, from 2023 onward. The two-seat KRX is covered from 2020.
Do Keller ball joints require A-arm modification?
No. Keller joints thread into the factory arm as supplied, so no machining is needed.
Can these be rebuilt instead of replaced?
Yes. They grease and adjust, and the Keller ball joint rebuild kit for Kawasaki services them with a new cup, boot and pin when the internals eventually wear.
Why Keller
Todd Keller designed the two-piece threaded ball joint to fix the one part of a stock front end that keeps failing, and SuperATV now builds and backs the line. The design has barely changed because it does not need to: thread the housing in like a nut and bolt, use a chromoly stud, and make the whole assembly serviceable so a worn joint gets rebuilt rather than binned.
Complete Your Teryx KRX Front End Rebuild
Because this is sold as a single joint, decide the quantity before you check out — four covers a complete front end. If the boots are torn but the joints are sound, the Keller boot replacement kit is the cheaper fix. If the joints are worn but the housings are good, the Keller rebuild kit for Kawasaki services them. Tie rods and A-arm bushings are worth inspecting while everything is apart.
