ATI Performance Damper for Honda H/F Series Engines

ATI Performance Damper for Honda H/F Series Engines

Dial-in bulletproof crankshaft protection and silk-smooth revs with the ATI Performance Damper for Honda H/F Series Engines. Designed around ATI’s race-proven Super Damper technology, this unit slides onto your H22, F20, or F22 crank just like the factory pulley yet annihilates the torsional vibrations that crack cranks, chew up main bearings, and rob horsepower.

Why you’ll love it

• Track-grade strength, street manners – A forged steel hub is press-fit and pinned to a 6061-T6 aluminum shell, while an elastomer-bonded inertia ring absorbs harmonics across the entire rpm range—perfect for 9,000-rpm NA screamers or big-boost turbo builds.
• Built for your serpentine setup – The outer shell retains the OEM six-rib belt profile and arrives with a removable bolt-on power-steering pulley, so accessories stay exactly where Honda intended.
• SFI 18.1 certified – Legal and trusted for NHRA, NASA, and SCCA competition.
• Laser-etched timing marks – Fast, precise ignition or cam timing adjustments from idle to redline.
• Two overdrive options – Choose 4% or 9% OD to spin that alternator and water pump harder when the revs climb.
• Direct fitment – Drops into 1994-2002 Accord and 1992-2001 Prelude chassis running H-series or F-series motors with no spacers, shims, or guesswork.

Results you can feel

• Crisper throttle response and smoother idle
• Extended accessory and bearing life
