Product Details

The KYB Gas-a-Just 551106 is a high-performance monotube shock absorber engineered to deliver superior handling and responsiveness compared to traditional twin-tube designs. This advanced shock technology automatically adjusts to driving conditions in real-time, providing both comfort during everyday driving and instant performance when you need it most.

Key Features:

  • Monotube design eliminates fade caused by aeration for consistent performance
  • Dual-chamber construction with separate hydraulic and nitrogen gas areas
  • Air-free hydraulic piston and valve chamber ensures precise control and responsiveness
  • High-pressure nitrogen gas chamber with floating piston provides adaptive damping
  • Instant automatic adjustment to changing road and driving conditions
  • Available as direct OE monotube replacement or performance upgrade for twin-tube applications

The Gas-a-Just design keeps the hydraulic fluid and nitrogen gas completely separated by a floating piston, ensuring the hydraulic fluid remains air-free for optimal damping characteristics. This configuration delivers a comfortable ride quality during normal driving while instantly providing enhanced vehicle control and stability during spirited driving, towing, or hauling.

Excellent price and easy transaction so far.

great Service, and easy to navigate there website to find the right part!

Awesome took almost no time to get what ordered.

I like it looking forward to Do it again.

Product was delivered and item was as discribed. However it did take a little longer to ship than what is the new normal. (3 business days ) shipping address to delivery address is 3 hours by car. Over all experience with this company was good.

Great pricing. (Check on google and they were the cheapest and had great reviews.) Quick shipment and everything is as they said it would be.

Best price I could find anywhere and it shipped right away!

Great
