Product Details

The KYB Gas-a-Just KG4507 is a high-performance monotube shock absorber engineered to deliver superior handling and fade-free performance. Unlike traditional twin-tube designs, this monotube shock utilizes advanced gas-pressure technology to instantly adapt to changing driving conditions, providing both comfort during normal driving and responsive performance when you need it most.

Key Features:

  • Monotube design eliminates shock fade caused by aeration for consistent performance
  • High-pressure nitrogen gas chamber with floating piston for instant response
  • Separate air-free hydraulic piston and valve chamber ensures precise control
  • Dual-chamber design provides comfortable everyday ride with on-demand performance
  • Can be used as direct OE monotube replacement or performance upgrade over twin-tube shocks
  • Automatic adjustment to performance demands without driver input

The Gas-a-Just design separates the hydraulic fluid from the nitrogen gas using a floating piston, maintaining optimal pressure and preventing fluid foaming that causes performance degradation. This engineering approach delivers the responsiveness and control serious drivers demand while maintaining ride quality for daily driving.

Just Googled what I needed found this site had cheapest price, click, pay, done...doesn’t get any simpler:)

Shipping was super fast, however product arrived with slight damage, had some minor paint chipping. Was disappointed, but installed anyways as I needed for use right away and didn't have time to return.

Fast

My satisfaction level literally could.not be higher! I ordered some tires online on a Saturday afternoon, and received a Shipping Notice, complete with a FedEx Tracking No., a short time later. And hat's off to their preferred shipper, FedEx, too!. Even though I placed my order only a couple of weeks before Christmas, I had my tires show up a day EARLIER than FedEx's original Delivery estimate! Product was exactly as ordered, and arrived in factory-new condition. So, no complaints ther, either... As I said, I would highly recommend Autoplicity.com to anyone!

Fast shipping!

Autoplicity was quick, and fast! the shipping was standard but arrived in five days! I would definetly recommend them!

Great prices and prompt shipping

The item I ordered was in stock and was shipped within 24 hours. The purchase process was quick and convenient. The website was easy to navigate. Their prices were the best I could find anywhere. I will definitely purchase from them again in the future. I am pleased with Autoplicity!
