The Wavetrac Audi A4 \u0026amp; S4 Quattro Differential is the only torque biasing differential on the market with patent-pending technology that mitigates wheelspin when an unloaded wheel condition arises. During zero axle load conditions, the Wavetrac cam device acts to create internal load, maintaining drive on the gripping wheel instead of acting like an open diff (and going nowhere!). Super strong 9310 alloy steel gears are enclosed in case-hardened steel bodies, held together with ARP fasteners. All Wavetrac rear differentials include a transferable, Limited Lifetime Warranty.\u003c\/div\u003e\u003ch2\u003eVehicle and Product Categories\u003c\/h2\u003e\u003cp\u003eWavetrac Differentials, AUDI \u0026amp; VW\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-309-180WK\u003c\/p\u003e\u003cp\u003e\u003cem\u003eVerify vehicle fitment and installation requirements before purchase.\u003c\/em\u003e\u003c\/p\u003e","brand":"Wavetrac","offers":[{"title":"Default Title","offer_id":46242248327253,"sku":"18-309-180WK","price":1695.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0947\/5040\/files\/F198644500.jpg?v=1790606122","url":"https:\/\/speedzone-web.com\/products\/wavetrac-rear-differential-01r-b5-b6-b7-audi-a4-s4-quattro-b5-rs4","provider":"Speedzone Performance LLC","version":"1.0","type":"link"}
