Product Details

The KYB Gas-a-Just KG9125 is a high-pressure monotube shock absorber engineered to deliver superior performance and responsiveness compared to traditional twin-tube designs. This advanced monotube configuration provides instant, automatic adjustment to changing road conditions while completely eliminating performance fade caused by aeration.

Key Features:

  • Monotube design with dual working chambers for optimal performance
  • Air-free hydraulic piston and valve area delivers precise responsiveness and control
  • High-pressure nitrogen gas chamber with floating piston provides consistent damping
  • Instantly adapts to performance demands without delay or fade
  • Maintains comfortable ride quality during normal driving conditions
  • Enhanced performance on demand when aggressive driving requires it
  • Fade-free operation eliminates loss of damping from oil aeration

The Gas-a-Just monotube design separates the hydraulic fluid from the high-pressure nitrogen gas using a floating piston, ensuring the hydraulic fluid remains air-free for consistent shock performance. This configuration allows the shock to react instantly to road inputs while maintaining the durability and reliability KYB is known for in performance suspension applications.

Good service good prices

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

Easy to use site.

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.

Fast shipping. And great cust service.

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