Pro XP suspension geometry

When you’re ripping through trails, climbing rocks, or blasting through mud, your Pro XP trailing arms are taking a lot more abuse than you might think. These rear suspension components are the link between your hub assembly and the chassis — meaning they control wheel position, help manage Pro XP suspension geometry, and absorb a fair amount of the impacts that your shocks don’t catch. Get them right, and your Pro XP rear suspension will feel smooth, stable, and predictable. Let them wear out, bend, or crack, and you’re in for sloppy handling, uneven tire wear, and possibly a ride-ending failure.

Why Trailing Arms Matter

In a Polaris RZR setup, trailing arms do more than just hold your wheels in place. They:

• Keep the rear wheels aligned under load and during suspension travel.
• Work with the shocks to manage weight transfer and Pro XP suspension upgrades.
• Maintain critical alignment settings like toe and camber.
• Strong, well-designed trailing arms — especially high-clearance trailing arms — also give you more room to clear rocks, stumps, and ruts without dragging the rear end.
