An Innovative, Two-Piece Ball Joint
The biggest problem with OEM ball joints is that they’re held in by a flimsy snap ring. All it takes is one big hit to push right past it and put a stop to your ride. That’s what Keller Ball Joints are built to fix. They use a threaded chromoly housing that won’t pull out just from hard impact or running huge tires. It’s no wonder why the original Keller design is still the best for your Polaris RZR Trail 900.
The Industry’s Best Durability
Keller Ball Joints were the first threaded ball joint on the market. The joint presses into the A-arms and then the housing threads onto the joint giving you a nearly unbreakable ball joint. The housings are made with durable tool steel and the stud is made from a high-quality chromoly alloy for incredible strength. To top it all off, they’re easily adjustable and greaseable so you can keep them running smooth for years.
Ride Your Way
Lift your RZR Trail 900, put on massive tires, and go hit some jumps! By eliminating the need for a weak snap ring, Keller Ball Joints can handle every kind of extreme ride. They’re designed to stop your weekends from being interrupted by a pointless ball joint break.

Comfortable and light!
Color: Brown, Size: Large
Wanted something that was going to be lightweight but had those longer sleeves because I do still get a tad chilly even on the warmer days. This is perfect, the fabric is lightweight and breathable, the loose cut around the waist adds to the top's "breathability," but it still keeps you cozy and warm on those chilly mornings! The brown is a lovely warm-coffee tone and it hasn't faded a bit in the wash. Very nice shirt to add to your collection!

looks nice, well made and styish.
This was a gift for a friend.
It is well made, has a good modern style to it, comfortable to wear, she is taller, and it fits her well. Its a bit warm, so a fall kind of clothing option.
