Product Details

The KYB Gas-a-Just KG5551 is a high-performance monotube shock absorber engineered to deliver superior handling and fade-free performance. Unlike traditional twin-tube designs, this monotube configuration offers instant automatic adjustment to changing road conditions and driving demands.

Key Features:

  • Monotube design with two separate working chambers for optimal performance
  • Air-free hydraulic piston and valve area provides responsive control and precise damping
  • High-pressure nitrogen gas chamber with floating piston ensures consistent performance
  • Fade-free operation eliminates aeration issues common in twin-tube shocks
  • Instantly adapts between comfortable daily driving and performance demands
  • Enhanced vehicle stability during cornering, acceleration, and braking
  • Reduces body roll and improves overall handling characteristics

The Gas-a-Just design separates the hydraulic fluid from the pressurized nitrogen gas using a floating piston, preventing fluid aeration that causes performance fade. This results in consistent damping force and improved vehicle control across all driving conditions, from highway cruising to spirited performance driving.

Fast and convenient

The service was extremely graduating and needed for my well maintained vehicle. This company made my family safety on the road. The other company could not compare. Thanks

fast and easy

Great selection

Best prices I've found

I easily found the parts I needed.Parts are cheaper than buying on Ebay.If the parts arrive quick I will use this company regulary.

I paid for 2nd day shipping and 5 days later they were shipped out. So, I should receive my rotors in a full week from when I paid for 2 day shipping. I called customer service and they discounted the shipping rate to ground service. At least they were polite and helpful in the phone.

great experience, good price, item arrived within 4 days of purchase, would do business with again in future !

By far the lowest price i've seen on the web for what i have been trying to get, the Injen SRI for my juke. Great price fast shipping! Ill buy all my car stuff here from now on.

Easy order placement, fast shipment
