{"product_id":"helical-gear-differential-19","title":"Helical Gear Differential","description":"The Wavetrac differential is a state-of-the-art helical gear differential designed, developed, and manufactured in the USA by Autotech Driveline. It incorporates patented technology that mitigates wheelspin during zero axle load conditions by creating internal load, maintaining drive on the gripping wheel rather than acting like an open differential.\n\nConstructed with the highest quality materials, the internal gears are crafted from high-strength 9310 alloy steel, while the diff bodies are machined from case-hardened steel billet.\n\nThis specific differential, part number 18.309.170WK, is designed for the front of Quattro Audi models, including the B5 S4 and C5 A6 2.7T, as well as the Audi 4.2L C5 A6 and A8 with a 6-speed manual transmission. All Wavetrac differentials come with a transferable, Limited Lifetime Warranty. Note that ring gear bolts are not included but can be reused.","brand":"Wavetrac","offers":[{"title":"Default Title","offer_id":52664114217272,"sku":"18.309.170WK","price":1695.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687539791.png?v=1784333470","url":"https:\/\/store.motormia.co\/products\/helical-gear-differential-19","provider":"MOTORMIA","version":"1.0","type":"link"}
