2025-2026 Polaris RZR Pro XP Max OEM Fender Extensions (64 inch)

You’ve already decked out your 2025+ Polaris RZR Pro XP and added Full-Coverage Fender Flares (Polaris Part Number 2890407) for your stock 64-inch width and stock 30's, yet the mud still flies like a wild storm. Finding out quick that these fenders you added put a dent in the problem...but it's still a problem! That’s where MudBusters Max Fender Extensions come in—install directly onto your OEM fenders and endure years of relentless off-road abuse. Spend less time scrubbing and more time dominating the trails. Crafted in the USA from tough, virgin HMWPE—not just any plastic, but material built to flex on impact, resist flying rocks, repel mud and water, and shrug off UV rays and chemicals. The smooth underside lets mud slide off easily during rinse downs. Designed to perfectly match Polaris’ OEM flare profile, these extensions offer balanced, aggressive coverage where it counts—front edges, mid-fenders, and rear exits—without adding unnecessary bulk or losing your Pro XP’s sharp factor
