Product Details

The KYB Gas-a-Just 551122 is a high-pressure monotube shock absorber engineered to deliver superior performance and fade-free operation. Unlike traditional twin-tube designs, this monotube construction provides instant response to changing road conditions while maintaining consistent damping characteristics under demanding driving situations.

Key Features:

  • Monotube design with two separate working chambers for optimal performance
  • Air-free hydraulic piston and valve area ensures responsive control and precise handling
  • High-pressure nitrogen gas chamber with floating piston technology
  • Fade-free operation eliminates performance loss from aeration
  • Automatically adjusts to driving conditions for enhanced comfort and control
  • Available as direct OE monotube replacement or twin-tube performance upgrade
  • Maintains comfortable ride quality during normal driving with instant performance on demand

The Gas-a-Just technology separates the hydraulic fluid from the nitrogen gas charge, preventing fluid aeration that causes fade in conventional shocks. This design delivers consistent, reliable damping performance whether you're cruising on the highway or tackling challenging road conditions.

I bought the wrong part. I wish I could of selected a part by the engine make and size.

Excellent everything went well thank you

Nice got items really fast

Very fast shipping. Very satisfied.

Just took a bit but very happy. Customer service was great!

I totally recommend the Goodyear "Gatorback belt". I drive an 2001 Tahoe 5.3l, had the squeaky serpentine belt, It was still a good shape belt, but the squeaks were more of a nuisance. So I decided to give the Gatorback Belt a try, and overall I love it. No squeaks, squeals, or any kind of noise. Its very quiet. Autoplicity made it easy for me to check and make sure this belt fit my year and model vehicle. I didn't have to contact customer service for anything, so far (haha).

Great experiance, fair price, fast shipping.

Found Autoplicity through price searching. Best price, easy to navigate site, quick service. Bookedmarked for future use!

Great prices

Very competitive price, responsive customer service, very satisfied.

Seller was quick and hasle free to deal with. Will purchase again from this seller.
