SuperATV Polaris RZR Pro XP Mega Keller Ball Joint

Your RZR PRO XP is the perfect platform for gettin’ buck wild with big tires and a lead foot. The only problem is your stock ball joints aren’t built for that brand of crazy fun. Upgrade to Keller’s Mega Ball Joints for the biggest meanest ball joints on the planet. The two-piece design and massively oversized components let you get away with just about anything on your Polaris RZR PRO XP.

Mega Strength That Doesn’t Compromise
Mega ball joints aren’t like others. They have oversized housings and studs that are so big, you have to modify your A-arms to use them. The bigger housings make room for studs that don’t neck down much at all and allow for a massive ball at the center. The housings are made with a combination of durable steels and the studs used advanced Chromoly steel. They’re as tough as it gets and virtually impossible to break.

Two-Piece Ball Joints Are Better
The worst part of your stock ball joint is the flimsy snap ring that’s supposed to hold everything in. Keller’s innovative two-piece design gets rid of it. The housing threads onto your modified A-arm like a nut and bolt, it’s practically impossible to pull out on a hard ride. Plus, they’re greaseable and adjustable so they can maintain like-new tension for years.

For Riders Who Get Wild
If you like to ride high with big lifts and massive tires that tear up components, Keller’s Mega Ball Joints are for you. The oversized components combined with the two-piece design make it the high bar for strength and durability. Spend more time behind the wheel and less time in the garage when you use Mega ball joints.
