All SPEC flywheels carry SFI certification.\u003c\/p\u003e\n\u003cp\u003eThe SB55A-2 is SPEC's aircraft-quality billet aluminum single mass flywheel for the N55 cars, cut for SPEC's non-ratcheting “-2” clutch kits. It removes the dual-mass damper and most of the rotating mass, so the engine picks up and settles faster between shifts. SPEC builds flywheels for specific driving environments and does not treat them as a one-fits-all lightweight part — consult SPEC or Speed Logic for a recommendation.\u003c\/p\u003e\n\u003ch2\u003eSPECS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: single mass billet flywheel\u003c\/li\u003e\n\u003cli\u003eMaterial: aircraft-quality billet aluminum\u003c\/li\u003e\n\u003cli\u003eCNC machined to a .001 in. tolerance for a flat clutch bedding surface and true balance at rpm\u003c\/li\u003e\n\u003cli\u003eSFI certified\u003c\/li\u003e\n\u003cli\u003eRebuildable, with a replaceable steel friction plate\u003c\/li\u003e\n\u003cli\u003eClutch compatibility: \u003cstrong\u003efor use with SPEC SB55x-2 \/ non-SAC clutch kits only.\u003c\/strong\u003e Will not work with the stock clutch or a SAC-pattern kit.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePARTS INCLUDED\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1x SPEC billet aluminum single mass flywheel\u003c\/li\u003e\n\u003cli\u003ePressure-plate-to-flywheel bolts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTECH RESOURCES\u003c\/h2\u003e\n\u003ch3\u003eAdditional Parts Required\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eA matching SPEC non-SAC clutch kit is REQUIRED\u003c\/strong\u003e — a SPEC N55 kit with a part number ending “-2” (SB551-2, SB552-2, SB553H-2, SB553-2, SB553F-2, SB554-2 or SB555-2).
