Product Details

If you're working on a 2003-2008 Yamaha YFM660F Grizzly 4x4 and need to replace a rear axle, this QuadBoss replacement is a solid option. It's made from high-strength 40CR chromium bar, which is precision-machined to fit just like the original equipment. This means you won't have any trouble getting it installed and it will function correctly with your drivetrain.

What sets this axle apart is its construction, which QuadBoss says exceeds OEM axle strength. It also features a laminate coating to help fight off rust and corrosion, keeping it looking good and working well for longer. The neoprene boots are designed to create a waterproof seal, protecting the internal components, and they're packed with high-performance molybdenum grease to keep heat and friction down, contributing to a longer cycle life compared to other aftermarket options.

You'll also find low-profile stainless steel clamps used on the boots, which are less likely to snag on things. This axle is a direct replacement, so it should fit right in where your old one came out.
