The G2 Pro Series is intended for racing and more extreme-duty applications. Keeping the two series separate allows builders to choose the transfer case that better matches how the vehicle will actually be used.\u003c\/p\u003e\n\u003ch3\u003eWhy choose the 3.0:1 Atlas instead of a deeper low-range ratio?\u003c\/h3\u003e\n\u003cp\u003eA 3.0:1 low range provides substantial additional gear reduction while maintaining a versatile overall crawl ratio. It is a strong choice for vehicles that need low-speed control in technical terrain but also spend time trail riding or operating at higher speeds. Final gearing should be considered with transmission ratios, axle gearing, tire diameter, engine characteristics, and intended use.\u003c\/p\u003e\n\u003ch3\u003eWhat is the advantage of a gear-driven transfer case?\u003c\/h3\u003e\n\u003cp\u003eA gear-driven transfer case eliminates the drive chain found in many factory transfer cases. The Atlas uses heavy-duty gearing and a rigid case design to provide high torque capacity, consistent power transfer, and durability for demanding off-road use.\u003c\/p\u003e\n\u003ch3\u003eWhat does the Atlas II 2-speed provide?\u003c\/h3\u003e\n\u003cp\u003eThe Atlas II provides a 1:1 high range and a dedicated low range. This 3.0:1 version multiplies drivetrain reduction by three in low range, giving the driver significantly greater control and torque multiplication for technical terrain.\u003c\/p\u003e\n\u003ch3\u003eWhat maintenance does an Atlas transfer case require?\u003c\/h3\u003e\n\u003cp\u003eChange the gear oil after the initial 500 miles and then approximately every 10,000–15,000 miles. Use the manufacturer-recommended GL-4 synthetic gear oil and inspect fluid condition, yokes, fasteners, and related drivetrain components regularly. Yoke bolts should also be checked and retorqued at the recommended service intervals.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003chr\u003e","brand":"Advance Adapters","offers":[{"title":"Default Title","offer_id":56942782382246,"sku":"ATLAS30","price":3059.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0693\/8394\/6406\/files\/Atlas30-WOD-1.jpg?v=1786480433","url":"https:\/\/wideopendesign.com\/products\/atlas-ii-transfer-case-3-0-trail-series-left-drop-wod-spec-configuration","provider":"Wide Open Design","version":"1.0","type":"link"}
