The ATI Super Damper replaces the factory pulley with a far more capable unit: a tunable elastomer design that cancels crankshaft harmonics across the whole rev range, protecting the crank and bearings and recovering the power those vibrations quietly cost you. It's SFI 18.1 certified for competition, rebuildable, and rated to 750 hp. One thing to know up front, it's a press-fit, not a slide-on, so plan the install accordingly.\u003c\/p\u003e\n\n\u003ch4\u003eWhat a Harmonic Damper Does\u003c\/h4\u003e\n\n\u003cp\u003eWorth understanding, because it's doing more than driving your belts.\u003c\/p\u003e\n\n\u003cp\u003eA crankshaft doesn't spin perfectly smoothly, every combustion event twists it and it springs back, setting up torsional vibration along its length. Left unchecked, that vibration is destructive: it fatigues the crank, wears the bearings, causes timing problems, and at high RPM can make the factory pulley's bonded rubber fail, throwing your belts and risking the front of the engine. It also saps power, those harmonics are a parasitic loss.\u003c\/p\u003e\n\n\u003cp\u003eThe ATI damper absorbs that vibration with a tunable elastomer design. It's actually two dampers in one, a 4\" inner damper and a larger outer damper in bolted shells, which together cancel the harmonics across the entire rev range rather than at a single frequency. It's far more effective and durable than the factory bonded-rubber pulley, and it won't come apart at high RPM the way a degraded stock pulley can. The result is a protected crank, longer bearing life, and the power those vibrations were costing you back.\u003c\/p\u003e\n\n\u003ch4\u003eBuilt for Competition, Rebuildable\u003c\/h4\u003e\n\n\u003cp\u003eThe construction and certification are serious.\u003c\/p\u003e\n\n\u003cp\u003eIt's an aluminum shell on a steel hub, and it \u003cstrong\u003eexceeds SFI 18.1 safety certification\u003c\/strong\u003e, which is required for NHRA and IHRA competition. If you race in a sanctioned class that mandates an SFI damper, this passes tech. It's rated to a maximum of \u003cstrong\u003e750 hp\u003c\/strong\u003e, so there's capacity well beyond most D-series builds.\u003c\/p\u003e\n\n\u003cp\u003eAnd it's fully rebuildable and field-tunable, ATI offers service kits and replacement elastomers, so it's a buy-once part you maintain and re-tune rather than replace, unlike the sealed factory pulley that you throw away when it degrades.\u003c\/p\u003e\n\n\u003ch4\u003eRetains the Serpentine Belt, 10% Underdrive\u003c\/h4\u003e\n\n\u003cp\u003eThe damper keeps your accessory drive working.\u003c\/p\u003e\n\n\u003cp\u003eIt features a \u003cstrong\u003e5.5\" 4-rib serpentine belt drive\u003c\/strong\u003e behind the outer shell, so it uses your factory serpentine belt setup, your accessories keep running as they should. The pulley is \u003cstrong\u003e10% underdriven\u003c\/strong\u003e, which slows the accessories slightly to reduce parasitic drag and free up a touch more power, a common, beneficial setup on a performance build. It includes 360° laser-etched timing marks for easier ignition and cam timing.\u003c\/p\u003e\n\n\u003ch4\u003eRead This: It's a Press-Fit Install\u003c\/h4\u003e\n\n\u003cp\u003eImportant, because this doesn't install like a factory pulley.\u003c\/p\u003e\n\n\u003cp\u003eUnlike the OEM crank pulley that slides onto the crank snout, the ATI damper is a \u003cstrong\u003e1-thousandth press fit\u003c\/strong\u003e, it has to be pressed onto the crank, which requires a damper install kit. Don't plan to tap it on or slide it by hand; you need the proper tool to install it correctly without damaging the damper or the crank.\u003c\/p\u003e\n\n\u003cp\u003eSo budget for a damper install kit if you don't have one, and know going in that this is a more involved install than swapping a stock pulley. It's a straightforward job with the right tool, but the wrong approach can damage parts, so do it properly.\u003c\/p\u003e\n\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\n\u003cul\u003e\n    \u003cli\u003ePart number: 918456\u003c\/li\u003e\n    \u003cli\u003eShell: 7.04\" aluminum\u003c\/li\u003e\n    \u003cli\u003eHub: steel\u003c\/li\u003e\n    \u003cli\u003eBelt drive: 5.5\" 4-rib serpentine (10% underdriven)\u003c\/li\u003e\n    \u003cli\u003eWeight: 7.4 lbs total; 3.4 lb inertia weight (2-ring)\u003c\/li\u003e\n    \u003cli\u003eRating: 750 hp max\u003c\/li\u003e\n    \u003cli\u003eCertification: exceeds SFI 18.1\u003c\/li\u003e\n    \u003cli\u003eTiming marks: 360° laser-etched\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\n\u003cp\u003e1992-1995 Honda Civic CX\/DX\/EX\/HX\/VX\/Si\u003cbr\u003e1996-2000 Honda Civic DX\/EX\/LX\u003cbr\u003e2001-2005 Honda Civic DX\/EX\/LX\u003cbr\u003e1993-1997 Honda Del Sol S\/Si\u003c\/p\u003e\n\n\u003cp\u003eD15, D16, and D17 engines.
