Product Details

The KYB Gas-a-Just KG4511 is a high-performance monotube gas shock absorber engineered to deliver superior handling and control compared to traditional twin-tube designs. This monotube design eliminates shock fade and provides instant response to changing road conditions, making it ideal for drivers seeking enhanced performance without sacrificing everyday comfort.

Key Features:

  • Monotube design with two separate working chambers for optimal performance
  • Air-free hydraulic piston and valve area ensures consistent responsiveness and precise control
  • High-pressure nitrogen gas chamber with floating piston maintains pressure and prevents fade
  • Instantly adapts to driving demands—comfortable during normal driving, firm when performance is needed
  • Fade-free operation eliminates aeration issues common in twin-tube shocks
  • Larger piston diameter provides improved vehicle control and stability
  • Ideal for trucks, SUVs, and performance vehicles requiring upgraded suspension

The Gas-a-Just design separates the hydraulic fluid from the nitrogen gas with a free-floating piston, ensuring the hydraulic fluid remains aeration-free under all driving conditions. This results in consistent damping performance whether you're commuting on smooth highways or navigating rough terrain. The high-pressure gas charge provides additional spring rate support to help reduce body roll and maintain vehicle composure during aggressive driving.

fast to find my part

Shopped around for a VDO gauge all over the internet incluing ebay, amazon and at least a dozen online retailers. Autoplicity was at least 10% cheaper than anybody else and a good 30% cheaper than most. The outstanding reviews made me more confident in ordering fom them for the first time.

great

I purchased an Airaid throttle body spacer, they has they cheapest price on the web, no one else could even compare to the prices here at Autoplicity, I will definitely order from in the future!

The prices and selection are best. The cutomer service rep. did a good job in handling all my questions, and placed my order. I will be using Autoplicity for all my auto parts.

Best price I found and VERY fast shipping. Very happy.
