Product Details

The KYB Gas-a-Just KG5489 is a high-performance monotube gas shock absorber engineered to deliver superior handling and responsiveness compared to traditional twin-tube designs. This monotube shock features advanced technology that automatically adapts to changing road conditions while maintaining consistent performance without fade.

Key Features:

  • Monotube design with dual separate working chambers for optimized performance
  • Air-free hydraulic piston and valve chamber ensures precise control and immediate responsiveness
  • High-pressure nitrogen gas chamber with floating piston design
  • Instant automatic adjustment to performance demands
  • Fade-free operation eliminates performance loss due to aeration
  • Balanced comfort during normal driving with enhanced performance on demand
  • Superior heat dissipation compared to twin-tube shock absorbers

The Gas-a-Just monotube design positions the piston and valving in direct contact with the outer tube, allowing for more efficient heat dissipation and consistent damping performance. The floating piston separates the hydraulic fluid from the high-pressure nitrogen gas, maintaining optimal pressure throughout the shock's travel range. This design provides improved handling, reduced body roll, and better stability during cornering while maintaining ride comfort for daily driving.

Great Price and Fast Shipping

Easy ordering and the best price I could find on the internet. However, I wouldn't have found this part by looking on the Autoplicity web site! The only way it showed up was doing a google search for that specific part.

I had a hard time getting to where I wanted but once there it was OK.

I ordered a windshield wiper fluid reservoir. It came on time and was the product I needed. It fit perfectly and works great.

Excellent prices, fast shipping, good customer services. I'm a very happy customer and I will buy again from them.

Best price available on the web. Fast shipping!
