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 D-series - Street (D15x, D16x, D17x)
ATI Performance Products has developed Super Dampers for the Honda D-series for street and racing applications. The D-Series Super Damper (Part # 918456) comes with 360° laser-etched timing marks and features a 4-rib 5.5" serpentine belt drive behind the outer shell to utilize the factory serpentine belt set-up. All D-series Super Dampers exceed SFI 18.1 Safety Certification and are approved for NHRA & IHRA competition.
Total weight (2-ring): 5.00lbs / Inertia weight: 3.40lbs

Honda B-series - Street (B16A/B, B17A, B18A/B/C,  B20x)
ATI has designed a 5.5” damper for the Honda B-Series engine for high horsepower street use. This new design is a direct replacement for the stock OEM Acura Integra B18 and Honda CRV B20 damper. The heart of this unit is the tried and true "damper within a damper” design that has put ATI ahead of the rest. The outer shell has been machined with the necessary multigroove pulleys to utilize the factory serpentine belt set-ups. The damper includes a removable serpentine style power steering pulley for ‘94 and newer B-Series applications, with the V-groove power steering pulley available upon request for the earlier B-Series applications.
Total weight (2-ring): 3.60lbs / Inertia weight: 2.20lbs

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.

Love the new pillows! Even though there smaller than my last larger pillows. I would recommend these pillows if you do just want a smaller fluffy ones.

The king size pillows do not offer the same firmness and comfort as the standard size.
Color: White, Size: King (Pack of 2)
I buy a lot from from Amazon and this is my first negative review as this was one of my biggest disappointments. I have bought 7 sets of this Basic pillow in the Standard size over the past 4 years, for my home and my boyfriends, using them both to sleep on and for my pillow shams. I love these pillows and my guests do too, best sleep ever and I have tried a number of expensive pillows prior to this. So when I recently purchased my first king size bed, I bought two sets of the king size pillow of this same brand, and I hate them. They are not the same as the standard size as they are flat, and no matter how much I tried to fluff them up, they fall flat in filling and firmness. After a few restless nights using my new king size pillows, I used the standard pillows I purchased in the past and there is definitely a difference. I see where there are different reviews/opinions on this, but this has been my experience. I will be complaining to Amazon, though not sure there is anything they can do since I used them.

Ok, not as good as before, put in dryer to fluff!
Color: Grey, Size: Standard (Pack of 2)
I have ordered these a few times in the past and loved them. This time they came rolled up and vacuum sealed. Doing that made the pillows flat and feel worn out. I was going to return them, but read that putting them in the dryer on low heat for about 15 minutes helps fluff them. I did that and it definitely improved the pillows. I'll keep them, but they're def not as good as they were a few years ago.

Luxury pillows
Color: White, Size: King(2Pack)
I purchased these pillows to be used as sham fillers, however, the pillows are so great I am now using them for sleeping. The filling conforms to your sleeping position and provides a comfortable sleep. They come rolled in plastic and are paper thin. Once removed, they fluff up beautifully and very evenly. These pillows are high quality and a good value for the price. Highly recommend.
