Bent factory radius rods throw off the rear alignment on a Polaris RZR XP 1000 and can leave the back end wandering. These adjustable rear radius arms are made from extra-high-strength, thermo-mechanically rolled steel, the same kind of material used in truck chassis and cranes, for 4x the strength of stock. The pivoting inner mount moves vertically and horizontally instead of binding like a fixed heim, which protects the bushings and lets the suspension move freely. They fit the XP 1000 and XP 4 1000.
Highlights
- Enhanced maneuverability
- Pivoting inner mount eliminates premature bushing wear
- Adjustable heim joints
- Hand welded for added strength and style
- Excellent strength-to-weight ratio
- 4x the strength of stock
Pivot Point That Works with the Suspension
Many aftermarket radius rods use a fixed heim at the inner mount, which restricts movement. These arms use a pivot that lets the rod move both vertically and horizontally at the inner mount without loading the bushings, which prevents premature wear and lets the machine work at its full potential.
Full Adjustability
Because they're fully adjustable, you can set rear alignment after adding a lift kit, high-clearance trailing arms or bigger tires without giving up ride quality.
Strength and Durability
Blast the whoops or take on heart-thumping hills with confidence. The high-strength steel and hand-welded construction make these arms 4x as strong as stock, built to take whatever you throw at them.
Choose Your Arms
Pick a color (Black, Orange, Red or Voodoo Blue) and your year (2014-2023 or 2024+). Note that Voodoo Blue and Velocity Blue do not match Polaris Sky Blue.

Who It's For and What Pairs Well
These are for RZR owners who've bent stock radius rods, added a lift or bigger tires, or want adjustable rear alignment. They will not fit with Polaris rear bumpers, so plan on an aftermarket rear bumper from RZR XP 1000 bumpers if you run one. Pair them with trailing arms from RZR XP 1000 trailing arms, and see more options in RZR XP 1000 radius arms (4-seat: RZR XP 4 1000 radius arms).
Fitment
| Year | Make | Model |
|---|---|---|
| 2014+ | Polaris | RZR XP 1000 |
| 2014+ | Polaris | RZR XP 4 1000 |
Note: Will not fit with Polaris rear bumpers.
Installation
Install one arm at a time so the trailing arm stays located, and set the length to match stock before fine-tuning rear toe. Instructions are below.
