ATI Super Damper standard harmonic balancers are specifically designed for high-rpm engines. Their proven elastomer is designed and tuned to eliminate harmful crankshaft harmonics that cause parasitic horsepower loss. They are actually two dampers in one--a 4 in. diameter inner damper and a 6 3/8 in., 7 in., or 8 in. diameter outer damper in two shells that bolt to the crank hub. These dampers are engineered to all but eliminate worn parts and timing problems. They're tunable in the field, rebuildable, and extremely efficient at all rpm.

Honda K-series (K20A/A2/A3/Z1/Z3 & K24Ax)

ATI Performance Products has developed Super Dampers for the new Honda K-series engine for ‘02 Honda Civic Si & Acura RSX for both street and racing applications. The street version (Part # 918477) comes with 360° laser-etched timing marks and features a single serpentine belt drive on the outershell to utilize the factory serpentine belt set-up. Race dampers allow for the mounting of a dry sump oiling drive gear to the front of the pulley. All K-series Super Dampers exceed SFI 18.1 Safety Certification and are approved for NHRA & IHRA competition. 

Total weight (2-ring): 3.75lbs / Inertia weight: 2.20lbs
Total weight (3-ring): 3.60lbs / Inertia weight: 2.20lbs

Installation Note: ATI dampers are a 1-thousandths press fit, they do not just slide on like OEM crank pulley. They will need to be pressed onto the crank snout with a damper install kit.

True no-show socks that don’t slide down!
Size: Medium, Color: (100) White / White / Mod Gray, Size: Medium, Color: (100) White / White / Mod Gray
This is the first pair of no-show socks I’ve tried that actually don’t slide down into my shoes. Trust me… I have tried lots of different pairs and this is the one! They fit perfectly. They’re not too thick and they’re obviously durable because I wash them after each wear, so daily.

Great socks!
Size: Medium, Color: (252) Blush Beige / White / Castlerock
Love these socks so much I got a second package. I like how thin and airy they are and they never slide down my heel. For thin socks they’re pretty durable.

Best no-show socks ever!
Size: 6-10, Color: Black
If you're tired of wearing socks that slip off and show in your sneakers, then you need to try these amazing socks! They are designed to stay in place, even after being active all day. They are incredibly soft and comfortable, and they are truly no-show, so you won't see them at all. I've been using these socks for years and have never had any issues. In fact, I love them so much that I've bought multiple packs, and my family members have started using them too. Don't waste any more time with those annoying socks that slip off and show - give these a try and you won't be disappointed!
