ATI Super Damper for Honda/Acura K Series Engines
Put every last bit of crank-harmonic anxiety to rest with the ATI Super Damper for Honda/Acura K Series Engines. Engineered, machined, and SFI 18.1-certified in the USA, this two-piece steel hub/aluminum shell damper uses ATI’s proven elastomer ring technology to cancel torsional vibration across the entire rev range of your K20 or K24. The result: smoother power delivery, extended bearing life, and the confidence to spin past 9,000 rpm without fear of pulley walk or accessory-belt carnage.
Why it matters
- Street or strip ready – Part #918477 retains the factory six-rib serpentine layout and adds 360° laser-etched timing marks for painless cam tuning.
- Race-day adaptability – Outer shell accepts a dry-sump drive gear (sold separately) so you can upgrade oiling without swapping dampers.
- Perfect 5.67″ diameter for K20A2/K20Z3; functions as a mild under-drive on larger-pulley K24s and as an over-drive on the smaller K20Z1, giving you freedom to fine-tune accessory speed with belt choice.
- SFI-approved for NHRA & IHRA competition—bolt it on once, pass tech forever.
- Built to last – fully rebuildable, with service kits and replacement elastomers available directly from ATI.
