If you're looking to beef up your RZR's steering and suspension, the Kryptonite Death Grip Ball Joint is a solid choice. I've put this thing through its paces, and it really does make a difference. Designed with heavy-duty oversized internals, this ball joint is all about improving strength and rigidity compared to the stock setup. Trust me, if you're pushing your RZR to its limits, you want something that can keep up.
One of the standout features is the heat-treated 4140 Chromoly stud, which adds a layer of durability you just can???t overlook. Plus, it comes with a serviceable grease port, so you can keep it running smoothly without a hassle. And for those who like to tinker, the oversized thread on the retainer is a nice touch that adds to its overall robustness.
Installation? It???s a direct bolt-on replacement, which means you won???t need to break out the welding gear or anything crazy. Just follow the install instructions, and you???ll be good to go. Just remember, this ball joint is sold individually, so grab what you need for your setup.
This piece is made right here in the USA, which is always a plus in my book. It???s compatible with the Polaris PRO R and Turbo R models from 2022 onwards, so if that???s your ride, you???re in luck. Overall, if you demand the best for your RZR, the Kryptonite Death Grip is definitely worth considering.
