Product Details

The KYB Gas-a-Just 553380 is a high-pressure monotube gas shock absorber engineered to restore your vehicle's original performance capabilities. This premium replacement shock features advanced monotube technology that delivers superior handling and control compared to conventional twin-tube designs.

Key Features:

  • Monotube design with larger piston for improved fade-free performance and heat dissipation
  • Dual-chamber construction with separate air-free hydraulic piston and valve area for instant responsiveness
  • High-pressure nitrogen gas chamber with floating piston for consistent damping control
  • Provides comfortable ride quality during normal driving with on-demand performance when needed
  • Precision-engineered to restore OE monotube vehicle capabilities
  • Single shock absorber per unit

The Gas-a-Just series is ideal for drivers seeking to maintain or upgrade their vehicle's original monotube suspension performance. The nitrogen-charged design ensures consistent damping performance across varying road conditions and temperatures, while the floating piston prevents aeration and maintains shock performance under demanding driving conditions.

Great site with great prices! Ordered an O2 bung from these guys and it came earlier than expected. The bung looks of decent quality and definitely can't wait to get my wideband in to start tuning.

Ordered monroe struts and shocks best price I could find. Will order again from Autoplicity when I need something else for one of my cars.

Great price, wicked fast shipping. Will order from these guys again!

I love this site!

Great experience. Good service. Reasonable prices.
