About this product
Can-Am Maverick X3 ball joints fail at the snap ring, not the joint itself. Keller ball joints remove that failure point completely: the two-piece housing threads into the A-arm like a nut and bolt, so there is no clip to shear and nothing to pull out. Hardened 4340 chromoly, greaseable and rebuildable, and available as uppers, lowers, or a full front-end set.
This is Todd Keller's original threaded design, covering 64-inch and 72-inch X3 models from 2017 onward.
Key Features
- 4340 hardened chromoly steel construction
- Two-piece threaded design doesn't require a snap ring
- Easily adjustable, rebuildable, and greaseable
- Robust boot retaining ring prevents water intrusion
- No A-arm modification required, unlike the Mega version
- Sold as uppers, lowers, an upper and lower pair, or a set of four
Built To Solve: Maverick X3 Ball Joint Pull-Out and Snap Ring Failure
- Snap ring shears and the joint separates from the A-arm under load
- Clunking or knocking from the front end on rough ground and whoops
- Visible play when the wheel is rocked top-to-bottom on a jack
- Repeat OEM joint failures on an X3 running a lift or oversized tires
- Torn boots admitting water and grit so the joint wears from the inside
- Replacing the same joint often enough that it has become routine maintenance
Best For: Lifted and Big-Tire Can-Am Maverick X3 Builds
- 64-inch and 72-inch X3 owners running larger tires or added lift
- Riders who have already replaced OEM joints more than once
- Desert and dune riders loading the front end hard on landings
- X3 MAX owners carrying more weight through the front end
- Anyone rebuilding a front end who wants to do it once
If your A-arms are already modified for oversized housings, or you are building for maximum strength and accept the extra install work, the Mega Keller version is the stronger option.

FAQ
Why do Maverick X3 ball joints pull out of the A-arm?
The factory joint is held in by a snap ring seated in a groove. Hard landings and the extra leverage of bigger tires can deform or shear that ring, and once it goes the joint has nothing holding it. Keller joints thread into the A-arm instead, so there is no clip to fail.
Do these fit both 64-inch and 72-inch X3 models?
Yes. Coverage spans both widths from 2017 onward, including MAX, Smart-Shox and the 2022+ trims. Check the fitment list above against your exact model.
Do I need uppers, lowers, or both?
They are sold separately so you can replace just what has failed. Uppers and lowers are different parts on the X3. If you are rebuilding a front end at high hours, the set of four covers two uppers and two lowers.
Do Keller ball joints require A-arm modification?
Standard Keller joints do not. The Mega Keller version uses an oversized housing and does require modified A-arms, which is the main reason to pick one over the other.
How are they installed?
They thread into the A-arm rather than pressing in behind a clip. Todd Keller demonstrates the process in the official SuperATV video linked below. Support the machine properly and allow time to grease and set them correctly.
Can I rebuild these instead of replacing them?
Yes, and that is the point of the design. They grease and adjust, and the Keller rebuild kit for Can-Am services the X3 joints 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 Maverick X3 Front End Rebuild
Before ordering, confirm your width (64-inch or 72-inch), your model year, and whether you need uppers, lowers or both. If the joints are sound but the boots are torn, a boot replacement kit is the cheaper fix. If the joints are worn but the housings are good, the Keller rebuild kit for Can-Am services them. Riders doing a full front end usually check tie rods and A-arm bushings while everything is already apart.
