Polaris RZR RS1 High Clearance Boxed Radius Arms

Your RZR RS1's rear suspension takes a beating on the trail. Stock radius arms flex and wear out fast, leaving you with sloppy handling and expensive repairs down the line. These high clearance radius arms replace that weak link with something built to last.

What you're getting here is serious strength — these are about 4 times tougher than what Polaris bolts on from the factory. The design kills common weak spots by welding and reinforcing pivot blocks directly to heavy-duty steel arms. Inside, a monoball bushing does the pivoting, which means fewer places for things to break and better durability over time.

Built for Real Riding

The bushings themselves are zinc-plated carbon steel, machined to move smoothly inside the housing without binding up. That coating keeps rust and wear down, so they stay tight season after season. You're looking at a radius arm that won't let you down, whether you're hammering rock crawls or ripping open desert.

What You Get

• High clearance boxed steel arms (rear pair)
• Reinforced pivot blocks welded to the arms
• Zinc-plated bushings
• Lifetime Warranty
