Factory radius rods on the Polaris RZR XP Turbo bend easily, and fixed heim ends bind the suspension and chew through bushings. These Rear Radius Arms are built from an extra high strength, thermo-mechanically rolled steel, the kind used in truck chassis and cranes, for about four times the strength of stock. A pivoting inner mount lets the arm move both vertically and horizontally, so the suspension cycles naturally without wearing out bushings early.
Highlights
- 4x the strength of stock
- Pivoting inner mount eliminates premature bushing wear
- Adjustable heim joints
- Hand welded for strength and style
- Excellent strength-to-weight ratio
- Backed by a lifetime warranty (see manufacturer terms)
- Black, orange, red or Voodoo Blue
Why the Pivot Matters
A typical heim on the inner end is a fixed point that fights the arm's natural arc. The pivoting inner mount works with the suspension instead, which improves maneuverability and keeps stress off the bushings.
Room to Build
Full adjustability means you can add a lift kit, high clearance trailing arms or bigger tires and still dial in alignment without giving up ride quality.
Strength Where It Counts
The steel used here is thermo-mechanically rolled for high strength, and each arm is hand welded. That gives you the confidence to blast whoops or charge steep hills without worrying about folding a rod, while keeping weight reasonable for the strength you get.
Color Note
Voodoo Blue and Velocity Blue do not match Polaris Sky Blue.
