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 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.

Most durable fetch balls I know of.
Size: 2-pack, Style: Duo
These balls are the biggest balls of them all. Well, not the biggest, but the best. Every other ball she would chew up in short order and I'd be throwing her a floppy piece of rubber. She just wants to fetch, but if it's not bouncing, she can't catch it on the bounce. Got these balls in July and no damage to them. I just ordered another pair, but only because the other two somehow got stuck up in trees. We have some very old and very large oak trees so not so easy to retrieve. Hope they somehow drop someday. But in the meantime, Lassie will be happy with her new ones. Very highly recommended!

Works great for scent work! Bounce is great for air retrieve!
Size: 2-pack, Style: Duo, Size: 2-pack, Style: Duo
My dog doesn’t know he loves them yet but I do! They are a little softer so when we do air retrieve, I don’t have to worry as much about his teeth! I’m hoping he will learn to find them by smell vs sight. We often play in the evenings and he tends to loose his ball. Love chuck it! Right now, we have about 10 chuck it balls! The tennis balls don’t work for air retrieve! Chuckit does!!! Love the thrower too! Saves my arm!!!!

I guess the smell is offputting
Size: 2-pack, Style: Duo
My dog loves chocolate stuff. But for some reason, wasn’t a huge fan of these balls. She played with them a little bit, but they’re not her favorite.

Our German Sheppard loves these
Size: Medium
These cost a bit more than tennis balls, but they are so much nicer and longer lasting. For starters, they stay cleaner than tennis balls because they’re smooth rubber. Dirt won’t build up on them and if anything does stick, like grass or soil, it falls off once the dog slobber dries. They’re also thick, so they don’t fall apart or blow out like a normal tennis ball does in our dog’s jaws after 30 seconds. Our GS chomps on these like crazy and the only damage they’ve suffered is a crack that developed from the edge of the hole, but the crack is growing very slowly and none of these balls have totally failed yet. The balls do whistle when thrown ant high speed and that may help a dog track and locate it, but I’m not sure. Our neighbors hear the whistling too so it’s far from silent. Lastly the orange ball is easy to locate out in our yard, but the dark blue practically disappears.

Great for smaller dogs
Size: Small
These two balls are perfect for the smaller mouthed dog that loves to play fetch.
These balls are not only super durable (lots of teeth biting), but float in the baby pool we use for our miniature dachshunds.
The value here is much better than you’d find anywhere else. The noise, if bitten hard enough, was “low” at best. Easy to spot/find if overthrown. Will definitely buy again once these are in bad repair; so far, so good-love these for my fur babies!
