Upgraded your 2025 Polaris RZR Pro R or Pro S with Polaris Full‑Coverage Fender Flares (Polaris Part Number 2890407)—but mud is still sneaking past? That 74‑inch stance still slings plenty, and OEM flares alone don’t seal the deal. Purpose‑built extensions that extend off those OEM Full-Coverage Fender Flares, tame the spray, and stay tough for years. Spend more time ripping trails, less time rinsing clumps.
