While factory stock plates tend to crack around the crankshaft hub when punished under high torque and RPM conditions, the 4mm thick center plate utilized on a Hays flexplate handles the brute force. These flexplates are supplied with a precision double welded ring gear and feature multiple engine and transmission bolt patterns. All Hays flexplates are zinc-dichromate plated to resist corrosion and are SFI certified under specification 29.1.\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSFI-approved – legal for use in racing classes that require SFI certification\u003c\/li\u003e\n\u003cli\u003eFlexplate features a precision double welded ring gear \u003c\/li\u003e\n\u003cli\u003eHas 4mm thick center plate to resist cracking near crankshaft flange\u003c\/li\u003e\n\u003cli\u003eZinc-dichromate plated to resist corrosion\u003c\/li\u003e\n\u003cli\u003eCAD designed to provide optimum performance and reliability\u003c\/li\u003e\n\u003cli\u003eAvailable in Internal or External balanced versions\u003c\/li\u003e\n\u003cli\u003eApplications offered for a wide variety of engine and transmission bolt patterns\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Specifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Details:\u003c\/strong\u003e Fits 1997-2017 GM LS 4.8\/5.3\/6.0\/6.2\/7.0L - 168 Tooth - Internal Balanced - SFI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e# of Teeth:\u003c\/strong\u003e 168\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Chevrolet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Circle:\u003c\/strong\u003e 3 x 10.75 inch, 3 x 11.00 inch, 3 x 11.5 inch, 6 x 11.5 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBolt Pattern:\u003c\/strong\u003e GM 10-1\/2\", GM 10-3\/4\", GM 11-1\/2\", GM 11-1\/8\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenterplate Thickness:\u003c\/strong\u003e 4 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine:\u003c\/strong\u003e GM Gen III\/IV (LS)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Balance:\u003c\/strong\u003e Internal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Silver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Automatic Transmission Flexplate\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Flexplates\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSFI Approved:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSFI Certification:\u003c\/strong\u003e 29.1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle:\u003c\/strong\u003e Quick Launch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransmission:\u003c\/strong\u003e 4L60E\/4L65E, 4L80E\/4L85E, 700R4, Category, TH350, TH400\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation Notes:\u003c\/h3\u003e\n\u003cp\u003eIS NOT direct replacement for \"long crank\" LS engines.
