What vehicles does this ball joint kit fit?

This heavy-duty ball joint kit fits numerous Polaris RZR models. It's compatible with vehicles such as the RZR RS1 (2018-2021), RZR S4 1000 EPS (2019-2020), and RZR XP 1000 (2020-2021), among others. Always check the full fitment list for your specific model and year.

What is included in the QuadBoss ball joint kit?

This kit contains one heavy-duty steel lower ball joint, a snap ring, and a cotter pin. It is sold per A-arm, so you'll need to purchase two kits if you are replacing both lower ball joints on the same axle.

Why is a steel ball joint better than an aluminum one?

The heavy-duty steel case provides greater strength and durability compared to the original aluminum ball joint. This upgrade helps prevent premature failure and can save you from having to replace more expensive components like the A-arm or steering knuckle.

Product Details

What you get in this kit is a heavy-duty steel lower ball joint, designed to replace the original aluminum one on a variety of Polaris RZR models. This upgrade is a smart move if you've experienced premature wear or failure with your stock ball joints, or if you're looking to avoid replacing an entire A-arm or steering knuckle just for a worn ball joint. It's built to handle more demanding use than the factory part.

The ball joint itself features a heavy-duty steel case, which is a significant step up from the OEM aluminum. Inside, a POM-M90 bearing cup isolates the ball end, helping to ensure a long service life even under stress. This kit comes with everything you need for installation, including the snap ring and cotter pin, making it a complete replacement for one A-arm.
