The Wavetrac Differential is the only torque biasing differential on the market with patented 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 differentials include a transferable, Limited Lifetime Warranty. 10 BMW M12x1.5x24 bolts 33121205561 or 10 ARP bolts N.M12.150.24 required if performing your own welded ring gear service (already included with our \"Install Kit\").\u003c\/div\u003e\u003ch2\u003eVehicle and Product Categories\u003c\/h2\u003e\u003cp\u003eWavetrac Differentials, BMW\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 30-309-172WK\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":46242243379285,"sku":"30-309-172WK","price":1395.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0947\/5040\/files\/F198644508.jpg?v=1790605773","url":"https:\/\/speedzone-web.com\/products\/wavetrac-differential-bmw-e92-dct-335is-e8x-dct-f10-550i-e90-335d-215k","provider":"Speedzone Performance LLC","version":"1.0","type":"link"}
