{"product_id":"hd-overdrive-clutch-hub-and-shaft","title":"Sonnax HD Overdrive Clutch Hub \u0026 Shaft","description":"\u003cp\u003eOverdrive clutch hub and shaft failure is common in Chrysler 66RFE and 68RFE transmissions, in both completely stock units and heavy duty\/performance applications. The failure always begins with small cracks at the lubrication cross holes that migrate through the rest of the shaft, eventually resulting in catastrophic gear train failure.\u003c\/p\u003e\n\u003cp\u003eSonnax heavy duty overdrive clutch hub and shaft 72570-01 is a critical upgrade to protect any vehicle at any power level. Sonnax cryogenically treats the OE hub and shaft to make the base steel more stable then shot-peens the lubrication cross holes to greatly reduce crack formation and increase load capacity. The result is a highly reliable hub and shaft assembly that’s an easy, direct replacement for all 66RFE and 68RFE units.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eClutch hub and shaft is cryogenically treated\u003c\/li\u003e\n\u003cli\u003eShot-peened lubrication cross holes\u003c\/li\u003e\n\u003cli\u003eGreater crack resistance than original hub and shaft\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sonnax","offers":[{"title":"Default Title","offer_id":49129450143963,"sku":"68-ODCH-HD","price":895.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/4173\/0267\/files\/F198647564.jpg?v=1786544265","url":"https:\/\/suncoastperformance.com\/products\/hd-overdrive-clutch-hub-and-shaft","provider":"SunCoast Diesel","version":"1.0","type":"link"}
