The Maverick R makes more power than anything else in the class, and it puts all of it through a front end whose ball joints are retained by a snap ring. Keller ball joints delete that ring. The two-piece housing threads into the A-arm like a nut and bolt, so there is nothing to shear and nothing to push out — 4340 hardened chromoly end to end, adjustable, greaseable and rebuildable.
Sold as an upper, a lower, or one of each. Coverage runs from 2024 onward on the Maverick R and Maverick R Max.

FAQ
Why do Maverick R ball joints pull out of the A-arm?
The factory joint is retained by a snap ring seated in a groove. Under the loads this machine generates, that ring can deform or shear, and once it goes nothing is holding the joint in. Keller joints thread into the A-arm instead, so no clip sits in the load path.
Will these hold up to the power the Maverick R makes?
That is the case they are built for. The stud and housing are 4340 hardened chromoly, and Keller rates the stud to handle extreme shear forces. More to the point, the threaded housing removes the snap ring entirely, so the part of the stock design that actually lets go under load is no longer in the assembly.
Do these fit the Maverick R Max?
Yes. Both the two-seat Maverick R and the four-seat Maverick R Max are covered from 2024 onward.
Do Keller ball joints require A-arm modification?
No. These thread into the factory A-arm as supplied. Only the oversized Mega version requires machined arms, and no Mega joint is published for the Maverick R.
Do I need both an upper and a lower?
They are sold separately so you can replace a single failure, and as one of each if you are doing a corner properly. On a high-hour machine most riders do both positions at once so the front end is consistent.
Can these be rebuilt instead of replaced?
Yes, and that is the design intent. They grease and adjust, and the Keller ball joint rebuild kit for Can-Am services them with a new cup, boot and pin when the internals 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.
Build a Maverick R Front End That Matches the Engine
Before ordering, confirm whether you need the upper, the lower, or both, and select that position on this page. If a boot has split but the joint is still tight, the Keller boot replacement kit is the cheaper repair. If the joint is worn but the housing is good, the Keller rebuild kit for Can-Am restores it. Riders replacing joints at speed-run mileage usually check tie rod ends and A-arm hardware at the same time.
