Product Description
Keller Ball Joints Are Unbeatable
Your ACE’s stock ball
joints use a flimsy snap ring to hold them into place. Any bad bump can pop
them right out of your A-arm. That’s why Todd Keller built his original two-
piece ball joint to eliminate the snap ring. So install our Polaris ACE Keller
Ball Joints. With a stronger stud and threaded housing, it’s almost impossible
to pull these ball joints out just from hard riding.


Durability You Can Depend On
When you’re riding solo in
your ACE, the last thing you need is a breakdown. Keller Ball Joints give you
long-lasting durability thanks to their two-piece design. Press the joint in,
thread on the housing, and then enjoy your unbeatable ball joints. Thanks to
the all-chromoly construction, adjustable stud, and greaseable housing, you
can count on Keller to keep on going.

Built for the
Beast

Everybody likes to hit the trail hard, but your ride ends
short when the trail hits back. But with Keller Ball Joints—and no snap ring
to worry about—you can ride your Polaris as hard as you want without worry.

  • Two-piece threaded
    design doesn’t require a snap ring
