Product Details

The KYB Gas-a-Just KG5409 is a high-performance monotube shock absorber engineered to deliver superior handling and ride quality compared to traditional twin-tube designs. This advanced shock features a monotube construction that eliminates fade and provides instant responsiveness under all driving conditions.

Key Features:

  • Monotube design with two separate working chambers for optimal performance
  • Air-free hydraulic piston and valve area ensures precise control and responsiveness
  • High-pressure nitrogen gas chamber with floating piston technology
  • Fade-free performance eliminates aeration issues common in twin-tube shocks
  • Automatically adjusts to driving conditions for balanced comfort and control
  • Provides comfortable ride during normal driving with instant performance on demand
  • High-pressure gas charge maintains consistent damping characteristics

The Gas-a-Just design separates the hydraulic fluid from the nitrogen gas using a floating piston, preventing fluid aeration and maintaining optimal damping performance even under extreme conditions. This makes the KG5409 ideal for drivers seeking improved handling, reduced body roll, and enhanced vehicle control without sacrificing ride comfort.

Pricing was exactly the same as what my Google search revealed

Great thanks

Yeah I think I did good but some happened there you sent me an envelope that was 10 times the size of my package I guess that's why you charge me 7:50 for the shipping and I'm wondering was it too much because it cost $7.01 when I went back online and was looking for it I wonder if you gave me the wrong price for Black Friday

So far so good

All went well

My product came in faster than I expected to receive it and I am happy about that.

The order was shipped promptly, and everyone was is good working condition. I will order from here again!!

I needed these, glad you had them on sale

Easy

Pleasure to deal with, will use for future purchases as well.

I placed an order on Sunday and received my order on Wednesday morning. Product was carefully packaged and as advertised. Will buy from Autoplicity again. Thanks for the great service. Order number #18578

Very good price on k&n air filter, will definitely order from autoplicity again.

I ordered some floor mats for a Prius. Autoplicity was very competitive in their pricing. Not only that, they shipped quickly and had great feedback during and after I ordered. I would purchase from them again!
