Factory radius arms on a Polaris RZR XP Turbo S bend easily when the rear end lands on a rock or stump, and the pivot joints are a known weak point. These Tubed Radius Arms replace them with 1.25" DOM steel tubing and gusseted pivots, giving you the strength to ride harder. Heim joints come set to stock specs, and new bushings are in the box, so they go straight on.
Highlights
- 1.25" x .138" wall DOM steel tubing
- Pivot joints reinforced with gussets and extra material
- Heavy-duty 5/8 x 18 heim joints, preset to factory specs
- Adjustable pivot blocks give full camber adjustment
- Heavy-duty frame mount design
- All new bushings included
- UV-resistant powder coat; lifetime warranty
Thick Tubes, Stronger Pivots
DOM tubing with a .138" wall is thick and burly, far stiffer than the stock rods. The pivots, where OEM arms usually fail, get gussets and extra material so they hold up under hard hits.
Ready Now, Adjustable Later
Because the heims are set to stock length from the factory, you can bolt them on and ride without a full alignment. If you add a lift or bigger tires later, the adjustable pivot blocks let you dial in camber to match.
Fitment Notes
