{"product_id":"hays-steel-sfi-certified-flexplate-gm-ls-engines-10-030","title":"Hays Steel SFI Certified Flexplate - GM LS Engines - 10-030","description":"Constructed of thicker than stock steel plate to withstand the stress of high stall speed converters and high RPM engine Securely welded ring gear with dual bolt pattern for use with either Powerglide or Turbo-Hydromatic transmission Meets SFI specification 29.1 for racing Hays heavy-duty flexplates for high performance and competition engines are constructed of a thicker than stock steel plate, enabling them to withstand the stress of high-stall torque converters and high-RPM engines. While factory stock plates tend to crack around the crankshaft hub when punished under high torque and RPM conditions, the thicker Hays flexplate handles the force. These H.D. flexplates are supplied with a ring gear that is securely welded in place and feature dual bolt patterns for use with either a Powerglide or Turbo-Hydromatic torque converter. All Hays heavy-duty 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\u003eS.F.I. 29.1 Certified\u003c\/li\u003e\n\u003cli\u003e168 Tooth Ring Gear\u003c\/li\u003e\n\u003cli\u003eFor use on Internally Balanced Chevy V8 Engines\u003c\/li\u003e\n\u003cli\u003eZinc Dichromate Plated Finish\u003c\/li\u003e\n\u003cli\u003eFeatures 4L60E and TH350 Converter 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 1997-2017 GM LS 4.8\/5.3\/6.0\/6.2\/7.0L, 168-Tooth, Internal Balanced\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 Pattern:\u003c\/strong\u003e 4L60E\/TH350\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Bore (Register Diameter):\u003c\/strong\u003e 2.066\"\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\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\u003eTransmission:\u003c\/strong\u003e Category\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation Notes:\u003c\/h3\u003e\n\u003cp\u003eA crank adapter sleeve is required when mounting an LS engine to a GM 2-speed or 3-speed automatic transmission.
