This spring and washer replacement kit works perfectly for KitchenAid stand mixers. Many post‑2016 KitchenAid mixers no longer come with factory installed springs, and this set solves that problem. It firmly locks flex edge beaters onto the mixer shaft to reduce shaking and lower component wear, extending your mixer service life. Made of food‑grade 304 stainless steel, these parts feature great rust resistance and long‑lasting durability. Widely compatible with 3.5 quart to 8 quart KitchenAid stand mixer models, they fit precisely and hold attachments securely. Installation takes only about one minute with no complicated disassembly. Just rotate the spring into position and slot on the washer, then your mixer is ready for daily mixing tasks. It is a practical replacement accessory to upgrade and repair your existing stand mixer.
