{"product_id":"centerforce-centerforcer-flywheels-steel-31","title":"Centerforce Centerforce(R) Flywheels, Steel","description":"Centerforce P\/N 704142 Steel Billet Flywheel Conversion for GM LS Gen III and IV V-8 Engines  GM LS\/Vortec engine platforms have a crankshaft mounting flange for the flywheel that is about 3\/8\" closer to the back of the engine than earlier generation (pre-1997) GM small blocks. When performing an LS engine swap in conjunction with an early (pre-LS) manual transmission, this difference causes several issues. Centerforce now offers a 168-tooth Steel Billet Conversion Flywheel Part Number 704142 to facilitate these swaps. This flywheel mates to 1997 and later GM LS engines while offering the proper flywheel thickness (+0.400\") to use in conjunction with the mechanical clutch linkage on many common early model transmissions. These include: Muncie SM465, GM SM420, New Venture NV3550, Chrysler NSG370 , GM Muncie, Borge Warner T-10, Richmond 4 and 5-speeds   Centerforce flywheel #704142 comes pre-drilled with pressure plate bolt patterns for early GM 11\" and 12\" (3\/8\" bolts) as well as late-model metric GM 11\" and 12\" patterns with dowel pins. See Centerforce Product listings at www.centerforce.com or contact our tech line at 800-932-5882 for more information regarding pressure plate and disc combinations for your LS swap application.  Note: Centerforce flywheel #704142 is not compatible with the GM 4.3L V-6 or Atlas series engines.\u003cp\u003e\u003cbr\u003eSpecifications:\u003cbr\u003e\u003c\/p\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_ABR\u003c\/td\u003e\n\u003ctd\u003eSFLY\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_DEF\u003c\/td\u003e\n\u003ctd\u003eClutch Flywheel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_DES\u003c\/td\u003e\n\u003ctd\u003eCenterforce(R) Flywheels, Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_EXT\u003c\/td\u003e\n\u003ctd\u003eCenterforce(R) SFI-certified steel flywheels are CNC-machined from billet steel for precise, no-hassle, bolt-in installation.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_FAB\u003c\/td\u003e\n\u003ctd\u003e0.400 in.
