RackBoss 2.0 Lasts Longer
No matter what rack you have, it’s gonna wear out eventually. When it does, the sloppy steering will make it tough to control your RZR. That’s why we made RackBoss 2.0. It’s an evolution of our original RackBoss that uses X24 Tech to reduce wear by over 50%. Put SuperATV’s RackBoss 2.0 Rack and Pinion on your Polaris RZR 900 to ride hard and get silly without ruining your steering system. It’s built for big lifts, big tires, and treacherous rides.

Less Wear and Tear with Our Dual-Bushing Design
What makes RackBoss 2.0 so good at preventing slop? It’s engineered with X24 Tech—heavy-duty PTFE bushings at both ends of the rack that remove play from the internals. Reducing play also keeps the tension spring nearly motionless. With little to no unintended internal movement, this rack can turn massive tires through heavy rides and hard hits and still stay in like-new condition for years longer than the next best rack. And with the built-in grease fitting, you can push fresh grease through after you go deep in mud or water.

Solid Steel Bar Tie Rods
For a beefy tie rod setup, you want to go with solid steel bar tie rods. They’re made with 1” diameter steel bars that are paired with bigger, better tie rods you’ll love—3/4” outer heim joint tie rods and rebuildable inner tie rods that use 3/4” rod threads and 16 mm rack threads. Altogether, they’re built for hard hits, big tires, and wild rides.

Swaged Tube Tie Rods
Our swaged tube tie rods are super sturdy but lightweight. The 7/8” diameter tubing flares out to boost its strength even more and comes paired with tougher tie rod ends. They have huge 16 mm rack threads and 14 mm rod threads that are the toughest you can get. This kit will keep you in control.

Looking for a More Traditional Rack?
If you don’t need all the benefits of a RackBoss 2.0, you can dial it back to our original, more traditional RackBoss 1.0. It uses the same beefy housing but doesn’t include the extra PTFE bushing. Our RackBoss 1.0 Rack and Pinion comes with steel swaged tubes that are tougher than stock and perfect for casual riders looking for an upgrade. It’s finished with our tough 14 mm inner and outer tie rod ends so you can ride harder without worry.

Very good chair, comfortable and high quality.
Color: Black
I had my doubts, yet after a couple months I really love this chair. Its a very good quality. Comfortable and sturdy. It allows for me to lean back too, which is a big plus! It looks really great and I am glad I purchased this chair. If you are looking, then just buy it because it is as good as it looks in the pictures.

Perfect for my studio
Color: Black
Naught this chair for my bedroom home recording studio. Honestly, I bought it mostly for the look. I just thought it would look great with what I was trying to v to do in the studio. I was very pleasantly surprised to find that’s its much more comfortable than I had assumed. It was easy to assemble. The provided assembly instructions were clear and easy to follow. It took me less than 20 minutes to build it. The build quality is solid. I’m a tall well build dude that weights more than 210 lbs and it takes my weight very well. Great little chair. I recommend it.

Very happy customer!
Color: Cream White, Color: Cream White
This chair is what you are looking for!!! No serious friends, this chair is everything and so incredibly comfortable! I’m so happy with this purchase. The wood accents I believe are actual wood and the PU leather is gorgeous and seriously looks like real leather. The size is perfect for my frame too. I’m a size medium bottom girly and the curve and level of cushion on the seat is so well executed. The rollability of the rollers are fantastic too, not super loud on our wooden floors and a really smooth glide. Im on the search for a rug to go under my desk but man the patience I used to wait to find this chair truly was worth it. A total lesson on patience and biting when you find the right thing. I think it’s pretty sturdy too. But I’ll report back in a few months. At the moment nothing leads me to be suspicious of a less than long life for this chair.

Good product, could improve backrest depth.
Color: Cream White
Comfortable seat. Stylish looking. Works well. Con is that the backrest is too far away, I had to add a lumbar support pillow. I also added a waffle seat for added comfort as I sit all day in the office. Easy to assemble. Color is nice. Feels sturdy. Rocks back, nice feature. Smooth wheels.
