East Lake Axle rear left or right cv axle for Polaris Sportsman 570

Our review of the East Lake Axle rear left or right CV axle for Polaris Sportsman 570 covers fit, construction, and real-world reliability for owners who need a direct replacement. This axle is aimed at owners of 2015-2023 Polaris Sportsman 570 machines and similar models who want an OEM-style, heavy duty upgrade that includes boots, hardware and a 2 year no fault warranty. The biggest reason to buy is its direct fit and heavy duty 4340 Cr-Moly steel shaft, which promises a stronger replacement than many stock axles while keeping installation straightforward.

Key Features

• Direct OEM replacement: Designed to match the factory fit for qualifying Polaris models so installation is typically plug-and-play for compatible machines.
• Heavy duty shaft: The 4340 Cr-Moly steel shaft provides higher strength compared with standard shafts, which can reduce bending or breakage under load.
• Complete assembly: Ships as a brand new complete CV axle assembly with boots, cotter pin, inboard clip and nut, reducing the need to reuse worn hardware.
• 28-tooth inboard spline: The axle features 28 teeth on the inboard spline, so verifying spline count prevents fitment problems.
• Two year protection: A 2 year no fault warranty gives added peace of mind against early failures or manufacturing defects.

Who It's For

This axle is best for owners of 2015-2023 Polaris Sportsman 570 models and other listed 4x4 and 2x4 machines who need a complete, ready-to-install replacement and prefer a stronger aftermarket shaft. It will appeal to riders who value an OEM-like fit but want a heavier duty component for trail or light utility use.

It is not for machines that use a different spline count or a dissimilar rear axle configuration; buyers should verify the inboard spline has 28 teeth and cross-check their exact model year and variant before purchase. Riders seeking a custom performance axle or a branded factory part may want to compare alternatives.
