Product Details

The KYB Gas-a-Just monotube shock absorber is engineered to restore and enhance your vehicle's handling performance with high-pressure monotube technology. Designed as a direct OE replacement, this performance shock delivers superior responsiveness and control compared to standard twin-tube designs.

Key Features:

  • Monotube design with two separate working chambers for optimal performance
  • Air-free hydraulic piston and valve area provides instant response and precise control
  • High-pressure nitrogen gas chamber with floating piston separator
  • Maintains comfortable ride quality during normal driving conditions
  • Delivers enhanced performance on demand during spirited driving
  • Eliminates aeration and foam buildup that can affect twin-tube shocks
  • Larger piston diameter improves heat dissipation and fade resistance

The Gas-a-Just design separates the hydraulic fluid from the nitrogen gas charge using a floating piston, ensuring consistent damping performance even under demanding conditions. This configuration makes it an ideal upgrade for drivers seeking improved handling, reduced body roll, and better stability without sacrificing everyday ride comfort.

This website is very easy to shop on, it is easy to pay with amazon

I am glad I found Autoplicity! Great prices, fast shipping, and excellent customer service. Already looking at other items to purchase from them. I highly recommend using Autoplicity!

The price is right but shipping cost is high. I bought a transmission seal for $12.91 and shipping was $13.31. The box it shipped in was about 10 times bigger than the part itself. Reduce the box and reduce my shipping cost please ! Else than that the part was in good condition, it was packed right and shipping time was reasonable.
