50 Caliber Racing - UTV and Off Road Parts Manufacturer since 2001
Your Polaris RZR isn't just a toy—it's your four-wheeled partner in crime! Whether you're rock-crawling, trail-blazing, racing or tearing it up in the dunes, you need parts that can handle the heat. Made in the USA, these bad boys aren't just some fancy upgrade; they're the kind of muscle your UTV needs to keep it rock-solid when you're going full throttle.
Aftermarket Heavy-Duty Radius Arms - Give Your Polaris RZR the Upgrade It Deserves!
Compared to the slim, flimsy stock radius arms, our heavy-duty design is like night and day. While the factory setup might bend or flex under pressure, our radius arms are built with durability, and reliability in mind, all wrapped up in one beefed-up package. ;)
Crafted from durable 6061 billet aluminum, these radius arms are built to withstand the toughest conditions. Whether it’s mud, rocks, or sand, these arms thrive in the face of any challenge. Proudly made in the USA, they come with the peace of mind of a guaranty—ensuring that no matter what, you're covered for the long haul.
**Does not include normal wear and tear on heim joints**
Do you want the raw beauty of billet to show off under the sun or the rugged durability of black powder coating to handle whatever the trail dishes out? At 50 Caliber Racing, it's like BK, you can have it your way and you can count on these radius rods looking as good as they perform.
These radius rods didn’t just come out of nowhere—they were born after bending a whole lot of rods and getting through more than a few race-day mishaps. Built by those who know exactly how to push a UTV to its limits, these heavy-duty arms have been race-tested and proven in the harshest conditions. Whether your RZR is hitting the track, the trails, or just pushing the envelope on your weekend dune rides, these arms won’t bend under pressure!
