The Toughest Ball Joint on the Planet
Your RZR Turbo
doesn’t pull any punches. When you hit the gas, it goes, and your ball joints
better be ready. Stock ball joints rely on a flimsy snap ring and a crummy,
necked-down stud to keep them in one piece. But if you want a ball joint that
can survive any crazy ride you need Keller’s Mega Ball Joints for your Polaris
RZR XP Turbo. The two-piece design and massively oversized components mean
there’s nothing that will stop them.

All In on Mega

Mega ball joints are the toughest you can get. The
maximized housings make room for the biggest ball and stud in the industry. It
barely necks down at all! Plus, the housings are made with durable tool steel
and the studs use a high-quality chromoly alloy. They’re so big and strong,
that you have to modify your A-arms to make them fit. They’re the ultimate
ball joint for folks that go big and break everything.

Two-Piece Design You Didn’t Know You Needed

Keller Ball Joints
were the first threaded ball joint on the market. The joint presses into your
modified A-arms and then the housing threads onto the joint like a bolt and
nut to make it virtually impossible to pull out. No flimsy snap ring here! To
top it all off, they’re easily adjustable and greaseable so you can keep them
running smooth for years.

For the Biggest, Beefiest

Lift your RZR Turbo, put on massive tires, and go hit
some jumps! By making every component bigger and eliminating the need for a
weak snap ring, Keller Ball Joints can handle every kind of extreme ride.
They’re designed to stop your weekends from being interrupted by a pointless
ball joint break.
