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!).\n\nSuper strong 9310 alloy steel gears are enclosed in case-hardened steel bodies, held together with ARP fasteners.\n\nAll Wavetrac differentials include a transferable, Limited Lifetime Warranty.\n\u003cbr\u003e\u003cbr\u003e\n*Longer ring gear bolts required on factory LSD models (due to thicker RG flange) factory open diff models use original bolts\n\u003cbr\u003e\u003cbr\u003eFor 8T pinion, 31T ring\u003c\/div\u003e\u003ch2\u003eVehicle and Product Categories\u003c\/h2\u003e\u003cp\u003eWavetrac Differentials, Porsche\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 40-309-140WK\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":46242247409749,"sku":"40-309-140WK","price":1995.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0947\/5040\/files\/F198644032.jpg?v=1790606052","url":"https:\/\/speedzone-web.com\/products\/wavetrac-differential-porsche-915-18t-911-930-1974-77","provider":"Speedzone Performance LLC","version":"1.0","type":"link"}
