Product Details

The KYB Gas-a-Just 555609 is a high-performance monotube gas shock absorber engineered to deliver superior handling and ride quality. Unlike traditional twin-tube designs, this monotube shock features advanced technology that instantly adapts to changing road conditions while maintaining consistent performance without fade.

Key Features:

  • Monotube design with two separate working chambers for optimal performance
  • Air-free hydraulic piston and valve chamber ensures responsive control and precise handling
  • High-pressure nitrogen gas chamber with floating piston provides adaptive damping
  • Eliminates performance fade caused by aeration during demanding driving
  • Delivers comfortable ride quality during normal driving with instant performance on demand
  • Can be used as an OE monotube replacement or as a performance upgrade over OE twin-tube shocks
  • Automatic adjustment to performance needs without driver intervention

The Gas-a-Just monotube design separates the hydraulic fluid from the high-pressure nitrogen gas using a floating piston, preventing fluid aeration and maintaining consistent damping performance. This makes it an ideal choice for drivers seeking improved handling, reduced body roll, and enhanced vehicle control without sacrificing ride comfort.

100% Satisfied ...

Excellent price hoping product is just excellent or better

Fantastic transaction!

easy to order, fast delivery.

Product in stock, easy ordering, fast delivery and good price. First time, will return.

Best price around...and i take a lot of time looking around

Grateful to get e-mails concerning my order throughout the shipping time so I knew where it was and when to expect it

Great prices on parts.

Great product and fast shipping!

Mazda cargo mat for the CX-9 SUV came within 1 week. Mat fits perfectly; just as described. Autoplicity had the best price listed for this product; we are very pleased.

Very satisfied! My intake shipped on Friday and I received it on Tuesday. Not only super fast shipping, but a great deal to boot!

Almost a perfect score! I was pleased with the customer service but knowledge about their products warranties was lacking. Other than that, the representative that I spoke with on the phone was great. He was friendly and had a good overall knowledge of the products I was asking about. Pointed me in the right direction because I couldn't be happier with my bike rack. They had the best prices, lowest shipping costs, and my order arrived a day early. Great website to work with. I will definitely be doing business again and spreading the word about Autoplicity.com.

I bought a bicycle rack. It seemed like the product was delivered before I had even known it was shipped. Great price!

I got all of my parts in and where happy with them. The website is about the cheapest around. Something about them really gives me a good feeling. :)
