SuperATV Polaris RZR Turbo S Mega Keller Ball Joint

Your Turbo S is one heck of a rig. With its extra-wide suspension, you can keep the pedal floored around more often than not. But when you upgrade to bigger tires, you need ball joints that can handle it. With Keller’s Mega Ball Joints installed on your Polaris RZR XP Turbo S, you’ll be able to take your machine to its limits and beyond without busting a ball joint. They use oversized components and a two-piece design for unbeatable strength.

Unbeatable Mega Strength
Bigger is better, that’s why Mega ball joints use bigger housings and studs. The bigger housings are made with durable tool steel and make room for massive studs. The studs don’t neck down as much as the competition and use a massive ball for extreme strength. These ball joints are so big, they require you to modify your A-arms to make them fit. They’re for folks that need reliable strength above all else.

The Most Durable Ball Joint Around
Keller Ball Joints aren’t just the first threaded ball joints on the market—they’re also the most durable. Once you press the joint into your modified A-arm and thread the housing on the back like a nut and bolt, there’s nothing that’s gonna get it out. Plus, they’re made with hardened Chromoly from top to bottom so they can take the heat. And since they’re easily adjustable and greaseable, you can keep them running smooth for years.

Ride However You Want
When you upgrade to Mega Keller Ball Joints, you can upgrade the rest of your machine without worry. Get wild with bigger lifts and meaner tires—with massive components and a two-piece design, you can push the limits and forget about bringing spare ball joints on your next ride.
