Description

The QuadBoss Replacement Axle 609475 is a durable, high-strength upgrade for Yamaha Grizzly 660 4x4 models from 2003-2008. Built from 40CR chromium steel and precision machined for exact OEM fitment, it delivers improved strength, corrosion resistance, and longer service life for reliable off-road performance.

Features include a 40CR chromium high-strength bar, precision machining for exact OEM fitment, low-profile stainless steel clamps, and a laminate coating that resists rust and corrosion. The neoprene boots create a waterproof seal, and the axle is packed with hi-performance molybdenum grease to reduce heat and friction.
