A Bigger, Better Ball Joint
When you ride your Polaris
RZR RS1, you have to be able to go big without breaking down. After all, you
don’t have a co-pilot to help you out of sticky situations. So get Keller’s
Mega Ball Joints for the most durable ball joint on the planet. They use
oversized components to give you all the strength you’ll ever need. And when
you combine that with their two-piece design, you’ll hit your machine’s limits
long before you break these ball joints.

Built with Mega

What makes Keller’s Mega ball joints so much tougher
than anything else? It’s the oversized housings and studs. They’re so big that
you have to modify your A-arms to install them. That extra size makes them
incredibly strong. Plus, the housings used durable tool steel and the studs
use and advanced chromoly alloy to boost strength even more. It’s extreme
strength that’s perfect for your extreme needs.

Beats Keller’s Durability

Keller Ball Joints are the high bar
for durability by eliminating stock’s flimsy snap ring. The two-piece design
presses in on one side of your modified A-arm and threads in on the other,
kind of like a bolt and nut. The result is a ball joint that’s virtually
impossible to pop out while riding. Plus, they’re extremely robust thanks to
the hardened chromoly housings and studs. To top it off, they’re greaseable
and adjustable for like-new operation over their entire lifetime.

Go Big with Better Ball Joints
Sometimes stock just
doesn’t cut it. When you want to go big with your rig, make sure you add Mega
Keller Ball Joints too. They’re perfect for lifted machines, big tires, and
wild rides. By eliminating OEM’s flimsy snap ring and maximizing strength, you
can count on them to handle all that extra weight without breaking a sweat.
