By swapping to a 300M hub gear, torsional capacity increases dramatically—bringing your locking hub strength closer to that of a full-time slug while keeping the drivability and flexibility of a lockout. This is a highly recommended upgrade when running RCV Dana 44 outers to prevent hub-related failures on the trail.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003chr\u003e","brand":"RCV Performance","offers":[{"title":"Default Title","offer_id":56095465996454,"sku":"D4342","price":99.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0693\/8394\/6406\/files\/D4342-30-Spline-Dana44-300M-Locking-Hub-Gear-1.jpg?v=1778100134","url":"https:\/\/wideopendesign.com\/products\/30-spline-dana-44-300m-locking-hub-gear-upgrade","provider":"Wide Open Design","version":"1.0","type":"link"}
