Product Details

The KYB Gas-a-Just 554378 is a high-pressure monotube gas shock absorber engineered to deliver superior performance and fade-free operation. Unlike traditional twin-tube designs, this monotube shock features a single-tube construction that provides instant automatic adjustment to changing driving conditions without experiencing performance fade due to aeration.

Key Features:

  • Monotube design with two separate working chambers for optimal performance
  • Air-free hydraulic piston and valve area ensures immediate responsiveness and precise control
  • High-pressure nitrogen gas chamber with floating piston maintains consistent damping
  • Fade-free operation eliminates performance loss from fluid aeration
  • Automatically adjusts between comfort and performance modes based on driving demands
  • Larger piston diameter than twin-tube designs for improved heat dissipation
  • Provides comfortable ride quality during normal driving with instant performance when needed

The Gas-a-Just monotube technology separates the hydraulic fluid from the nitrogen gas charge using a free-floating piston, preventing aeration and maintaining optimal damping characteristics under all driving conditions. This design delivers both daily driving comfort and enhanced handling performance when you need it most.

Wow. Ordered it on a Wednesday got it in 2 days....amazing....and to top it off my mandrel bent ss tubing was packaged infinitely better then I would of imagined. The price was amazing. I literally have no complaints. I will definitely order again. I will say that items on their website were not labeled well so I used vibrants website to look up part numbers so I could get the right parts. Search engine wouldn't bring up items via part number. Kinda confusing but for all I got simply awesome.

Autoplicity has the cheapest prices around and fast shipping. I will do business with them again in the future.

Great prices fast shipping bookmarked website!

I found what I wanted and it was overall a pleasant experience.

Quick and easy!
