If you value consistent nitrogen-charged damping, a strong 11mm coil spring, and the ability to set preload for specific riding conditions, this unit is a practical choice. If you require a softer, comfort-oriented ride or your bike’s mounting dimensions don’t align, consider alternative shocks that match those needs.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does this shock fit my dirt bike?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Compare your current shock’s eye-to-eye (240mm), overall length, and 10mm mounting-hole diameter to ensure fit.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I refill or adjust the nitrogen charge myself?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. The shock is pre-charged; only a qualified technician should alter the gas pressure.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"AuryngMD","offers":[{"title":"Default Title","offer_id":48084049854622,"sku":"B0FF5DD5LD","price":91.97,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/auryngmd-rear-shock-front-view.jpg?v=1785844765","url":"https:\/\/northtrailauto.ca\/products\/auryngmd-240mm-rear-shock-absorber-for-pit-dirt-bikes-11mm-heavy-duty-spring-nitrogen-charged","provider":"North Trail Auto","version":"1.0","type":"link"}
