SuperATV Polaris RZR RS1 Mega Keller 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 Strength
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.

Nothing 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.
