Product Details

The KYB Gas-a-Just 5510037 is a high-pressure monotube gas shock absorber designed to restore and enhance your vehicle's performance and handling capabilities. This premium replacement shock features KYB's advanced monotube design that delivers superior performance over traditional twin-tube shocks.

Key Features:

  • Monotube design with two separate working chambers for optimized performance
  • Air-free hydraulic piston and valve area ensures responsive handling and precise control
  • High-pressure nitrogen gas chamber with floating piston provides instant performance on demand
  • Larger piston diameter than twin-tube designs for improved fade resistance and heat dissipation
  • Consistent damping performance under varying conditions and temperatures
  • Direct OE replacement fitment for easy installation

The Gas-a-Just monotube construction allows the hydraulic fluid and nitrogen gas to work independently, eliminating air-to-oil mixing that can cause performance degradation. This design maintains a comfortable ride during normal driving while instantly responding to demanding conditions when you need enhanced control and stability. Ideal for vehicles that require improved handling, towing capability, or spirited driving performance.

I ordered a set of Mahle pistons after contacting them directly to obtain the correct part number for my needs. Searching that part number showed that Autoplicity had them in stock, although there was very little description for them on your website. The ordering process went smoothly and delivery and packaging were very good, also.

Very satisfy with product

great website and always has great stock

Just what I needed at the price I needed it at too

Cool found the exact hks filter I was looking for!

All is well At this point. I’ll update after the parts have arrived.

Really great so far. Fast,easy-great job!

Beat every competitors price!
