The Best Ball Joint You Can Get
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.

Cool gadget for you puppy!
Color: Red
Do you need a break sometime? Something that you puppy can play with for 20 or 30 minutes at a time? This is it! It goes around the place in random paths that will keep your puppy entertained and amusedZ. It not to loud and it lasts a long time and nothing has broken off form the rough play at all.

Great for small dogs with a big prey drive!
Color: Red
He loves it!! I have a small dog with a big prey drive and he goes absolutely crazy for this! A big plus for taking the boredom away, really perking up his mental attitude. It's also (at this moment) much cheaper than others that look very similar. Super easy to charge. My dog is a rescue and never learned to play with toys, has zero interest in stuffed toys and doesn't really understand play, but this isn't play to him: It's what he was born to do. He gives it a hearty Two Paws Up!

Our Yorkie Puppy Loves This Toy!!!
Color: Red
Warning: your pet may become completely obsessed
I’ve had this toy for about a year for my Yorkshire Terrier, Gia, and it’s easily the most successful toy purchase I’ve ever made. We even had to replace the first one after she loved it a little too much (chewed the string off), and have since bought more as gifts for friends’ pets. Great toy for small dogs (too fragile for bigger dogs) and active, young cats.)
What we love:
* Endless engagement: Gia ignores all her other toys and goes straight for this every time
* Interactive features: Subtle beeping + changing colored lights + unpredictable rolling patterns keep her hooked
* Energy burner: Perfect for indoor play on hardwood floors—she will chase it nonstop
* Rechargeable: Battery lasts several hours, even with frequent use
* Durability: Holds up well considering how rough she plays
Real-life note:
Gia will literally bring this toy to me to get me involved—and I have to limit her playtime because she won’t stop on her own.
Bottom line:
If you have a high-energy dog (or even a playful cat), this isn’t just a toy—it becomes their favorite activity… and possibly their entire personality.

I wanted it to be a good fit
Color: Red
This toy garnered my dogs attention for a day. We tried it inside but there's too many places it would go under. We tried ot outside and it was powerful enough in the grass so tried concrete patio. My dog lost interest sadly. It wasn't a good product for my dog.

My pup loved it.
Color: Red
“Bought this for my dog Loki and it was an instant hit. He usually loses interest in toys pretty quickly, but this ball kept him entertained way longer than expected. The lights and movement immediately grabbed his attention, and he spent a solid hour chasing, pawing, and carrying it around the house.
It’s durable enough for excited play, easy to charge/use, and even survived Loki’s dramatic ‘victory laps’ through the living room. Bonus: it tired him out enough for an actual nap afterward. Definitely worth it for high-energy dogs or curious pets.”
