Confidence-Boosting Front Diff Upgrade for Sportsman
Your Polaris Sportsman needs dependable 4WD engagement for work and trail riding alike. This upgraded Extreme-Duty Sprague and Armature Kit reinforces your front differential, for much better durability and reliability than stock setups.
Enhanced Armature Plate Durability
Stock-style armature plates can struggle under heavy torque, especially at the teeth. This straight-tooth design significantly improves strength, minimizing wear and reducing the chance of failure. Each tooth is built to withstand sustained stress and real-world abuse.
Long-Lasting Billet Aluminum Sprague Carrier
This sprague carrier is made for extreme conditions, thanks to the premium hard-anodized 7075-T6 aluminum construction. It includes new rollers and OEM-style springs to ensure consistent operation and hassle-free installation. Plus, it’s backed by a lifetime warranty.
