Yamaha Raptor 660R riders (2001-2005 models), if you've bent or damaged your rear axle, this replacement axle shaft is what you need to get back on the trails. This is the main rear axle assembly that includes the axle shaft itself and the axle nut. It's designed as a direct replacement for the OEM part on the YFM660R. A bent axle can cause horrible handling, vibration, and uneven tire wear, so replacing it is crucial for safety and performance. Installation requires some mechanical skill (you'll likely need to remove the rear wheel, brake rotor, sprocket, and possibly the bearing carrier), but it's a straightforward swap if you have the tools. Make sure this is the correct part for your specific year – the 2001-2005 Raptor 660R uses this one. Always use a torque wrench to properly tighten the new axle nut to spec. Don't risk riding on a bad axle; get this replacement and restore your quad's stability and ride quality.
