You’re cruising along enjoying how surprisingly smooth this rough trail is. Your brand new side-by-side’s specialized suspension works amazingly until bang! Something is hung up somewhere. Turns out, your low-hanging stock radius arms caught a rock and stopped your ride immediately. What you need are high clearance radius arms.
You might be a little bit confused about what radius arms are, what they do, or why upgrading them can make your your rides smoother and easier.
First, you might not know that there are a few different names for radius arms. They’re also called radius rods and rear suspension links.
Radius arms are a part of the rear suspension system. They are used in place of rear A-arms or struts. The advantage of radius arms has to do with camber—they help keep your tires and wheels tilted to the same degree through your suspension’s whole range of motion.
While you won’t see radius arms on every UTV on the market, you will find them on pretty much every sport side-by-side—Polaris RZRs, Maverick X3s, Honda Talons, and Teryx KRXs all have radius arms for rear suspension.
There are two big advantages to upgrading your radius arms:
When you have better ground clearance and strength, every ride goes smoother.
The extra ground clearance is in the name. High-clearance radius arms bend up from the hub to the frame to make them farther from the ground.
It’s obvious that this will help you get over more rocks, sticks, and other crap. What’s not so obvious is why this is such a big deal for rear suspension. The rear of your machine gets dragged along in whatever direction you point your front tires. You have less control over the rear, so you can’t deftly avoid that big honking rock.
This issue is compounded by the fact that when you’re moving forward, you’re not paying attention to what the rear of your vehicle is doing. One moment you dodge a boulder and the next it bangs right into your radius arms.
With high clearance radius arms, you get a much smoother ride. If you clear an obstacle in the front, you can count on it clearing in the back. They make it so much easier to navigate tricky terrain, and you don’t have to constantly worry about how your back end is going be positioned. They’re a worthwhile addition whether you’re running high-clearance front A-arms or not.
They’ll also get scratched up less and look nicer longer.
That brings us to the next great reason to upgrade: strength.
Not only will high clearance A-arms avoid getting banged up, but they’re almost always reinforced to be stronger than stock too. If you do manage to whack them, they won’t break as easily.
For example, our high-clearance radius arms are made with either a boxed design or using billet aluminum. Both are significantly stronger than the stock radius arms.
The boxed arms use multiple internal and external gussets along with thick steel plating and hand welded seems to make them almost impervious to damage. Our billet aluminum radius arms are made with tried-and-true solid bar of 6061 billet aluminum. They have an amazing strength-to-weight ratio.
If you want smoother rides and a more reliable machine, the time to upgrade is now. You can wait until you bang up your stock radius rods on a ride, but that’s just a good way to guarantee that you ruin a trip. Upgrade now to get your UTV to where it needs to be.
