The swingarm is the pivoting rear suspension arm that holds the rear axle or wheel assembly and lets it move up and down through its travel, while the rear shock controls that movement. It carries the machine's weight, drive loads, and every rear impact, so its condition directly affects rear-end stability, tracking, and ride quality on rocky, rutted, and uneven terrain. Riders most often replace a swingarm after a bent or cracked arm from a rock strike or rollover, play or clunking at the pivot, worn or rough bearings, a rear end that wanders or tracks crooked, uneven chain or tire wear, cracked welds, stripped or damaged mounting points, rust or corrosion, or damage from a hard landing or trail impact.\u003c\/p\u003e\n\u003ch3\u003eWhy Choose Genuine OEM Yamaha Parts?\u003c\/h3\u003e\n\u003cp\u003eChoosing original equipment manufacturer (OEM) parts ensures your vehicle maintains its factory-standard performance, reliability, and fuel efficiency.

Before replacing it, inspect the pivot bolt, bearings, bushings, rear shock, and axle hardware, since wear in any of these can cause similar symptoms. Because swingarms vary by model, model year, and trim, confirm the correct part and installation procedure using your Yamaha service manual or factory schematic, or contact us with your model and VIN and we will help you match it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How do mud, water, sand, and heat affect a swingarm on the trail?\u003c\/strong\u003e\u003cbr\u003eA: Mud, sand, and water can work into the pivot and wash out grease, wearing bearings and seals quickly, while moisture speeds up rust where the finish is scratched or chipped. Packed mud can also hide cracks and trap moisture around welds. After a muddy, wet, or sandy ride, rinse the rear suspension, dry it, and check the pivot for play or noise and the arm for cracks or bends. Follow your Yamaha service manual for correct installation, greasing, and hardware guidance so your rear end stays solid and tracks true.\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-top: auto; margin-bottom: auto; line-height: normal;\"\u003e\u003cb\u003e\u003cspan style=\"color: #ff2a00;\"\u003ePRO TIP: \u003c\/span\u003e\u003c\/b\u003e\u003ca href=\"https:\/\/buywitchdoctors.com\/blogs\/news\/yamaha-oem-vs-aftermarket-parts-comparison\" title=\"Direct link to Buywitchdoctors.com blog about Yamaha OEM vs. Aftermarket Parts: Are Factory Components Best for Your Trail Riding?\" rel=\"noopener\" target=\"_blank\"\u003e\u003cb\u003e\u003cspan\u003e\u003cspan style=\"color: blue;\"\u003eLearn More about Yamaha OEM vs. Aftermarket Parts\u003c\/span\u003e\u003c\/span\u003e\u003c\/b\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-top: auto; margin-bottom: auto; line-height: normal;\"\u003e \u003c\/p\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-top: auto; margin-bottom: auto; line-height: normal;\"\u003e\u003cb\u003e\u003cspan\u003e\u003cspan style=\"color: blue;\"\u003e\u003cspan style=\"color: #ff2a00;\"\u003ePRO TIP:\u003c\/span\u003e \u003ca href=\"https:\/\/buywitchdoctors.com\/blogs\/news\/utv-oem-swingarms-vs-aftermarket-swingarms-the-ultimate-suspension-comparison\" rel=\"noopener\" title=\"Direct link to Buywitchdoctors.com blog about ATV OEM Swingarms VS Aftermarket Swingarms: The Ultimate Suspension Comparison\" target=\"_blank\"\u003eATV OEM Swingarms VS Aftermarket Swingarms\u003c\/a\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cbr\u003e\u003cstrong\u003eUpgrade Your Ride's Rear Suspension Performance Today\u003c\/strong\u003e\u003cbr\u003eA factory-fit swingarm keeps your rear wheels aligned, your handling stable, and your ride controlled over rough terrain.
