Product Details

The KYB Gas-a-Just 553381 is a high-pressure monotube gas shock absorber designed to restore and enhance your vehicle's suspension performance. This premium shock delivers superior handling and control compared to standard twin-tube designs.

Key Features:

  • Monotube design with separate working chambers for optimal performance
  • Air-free hydraulic piston and valve area ensures instant responsiveness and precise control
  • High-pressure nitrogen gas chamber with floating piston maintains consistent damping
  • Provides comfortable ride quality during normal driving conditions
  • Delivers enhanced performance on demand during spirited driving or heavy loads
  • Direct OE replacement for easy installation
  • Fade-resistant design maintains performance under extreme conditions

The Gas-a-Just monotube construction eliminates aeration and foaming that can occur in twin-tube shocks, ensuring consistent damping performance. The nitrogen gas pressurization keeps the oil and gas separated via a floating piston, maintaining optimal shock response whether you're cruising the highway or tackling challenging road conditions.

I recently ordered 2 Borla Dual Round Intercooled Tips from Autoplicity.com for one reason and reason only...their prices can not be beat! No where else online can anyone match them! <br>

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!

Very satisfied. Good price and quick delivery.

Great prices, quick ship thanks!

It was easy to find everything and quick

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.

Best price found. Excellent customer service. Thank You!
