Product Details

The KYB Gas-a-Just KG4538 is a high-performance monotube gas shock absorber engineered to deliver superior handling and fade-free performance. Unlike traditional twin-tube designs, this monotube shock features a single-tube construction that instantly and automatically adapts to changing road conditions and driving demands.

Key Features:

  • Monotube design eliminates fade caused by aeration for consistent performance
  • Dual-chamber construction with separate hydraulic and gas chambers
  • High-pressure nitrogen gas charging with floating piston technology
  • Air-free hydraulic piston and valving for immediate response and precise control
  • Automatically adjusts to performance needs without driver input
  • Provides comfortable ride quality during normal driving with instant performance on demand
  • Available as direct OE monotube replacement or performance upgrade for OE twin-tube applications

The Gas-a-Just's innovative two-chamber design separates the hydraulic damping fluid from the nitrogen gas charge using a free-floating piston. This configuration ensures the hydraulic fluid remains aeration-free for consistent damping performance, while the high-pressure gas chamber provides progressive resistance during compression. The result is a shock absorber that delivers both daily driving comfort and enhanced performance when you need it most.

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

quick

extremely simple process

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

Very good customer service asked about a lot of different springs and parts for my Mazdaspeed 3.
