It’s an ideal upgrade for performance applications where race damage and sprag rollover is common, especially in high-torque vehicles. The Sonnax race is manufactured from case-hardened alloyed steel with softer core and custom designed with an inner diameter a few ten-thousandths of an inch smaller than OE races. This unique combination of features significantly improves sprag element engagement and rollover resistance.\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003eSonnax 34663HD-02 is the same thickness as the 4L80-E, 4L85-E OE part and .040\" thicker than the TH400. It is a direct replacement when used with 4L80-E and 4L85-E direct drums. It can be retrofitted with minimal drum machining to the TH400 roller clutch and sprag-style drums, where the extra race thickness adds to durability and expands clutch stack-up options when using a thinner intermediate clutch backing plate such as Sonnax 34144HD-01\u003c\/p\u003e\n\u003cul\u003e\n\u003cli style=\"text-align: left;\"\u003eImproved material and design guard against sprag failure\u003c\/li\u003e\n\u003cli style=\"text-align: left;\"\u003eIdeal for all stock and performance applications, regardless of power level\u003c\/li\u003e\n\u003cli style=\"text-align: left;\"\u003eDirect replacement for 4L80-E, 4L85-E units, easily adapted to TH400\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cstrong\u003e Specs:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli style=\"text-align: left;\"\u003eWidth: 0.795\"\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\n\u003cp style=\"text-align: left;\"\u003e \u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Sonnax","offers":[{"title":"Default Title","offer_id":47995095908574,"sku":"S34663EHD","price":79.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/5464\/5470\/files\/S34663EHD_1.jpg?v=1773769587","url":"https:\/\/transmissioncenter.net\/products\/th400-4l80e-intermediate-sprag-race-extreme-duty-sonnax-34663hd-02","provider":"Transmission Center","version":"1.0","type":"link"}
