Product Details

The KYB Gas-a-Just 551602 is a high-performance monotube shock absorber designed to restore and enhance your vehicle's handling capabilities. Engineered with advanced monotube technology, this shock provides superior performance for drivers who demand responsive handling without sacrificing ride comfort.

Key Features:

  • Monotube design with two separate working chambers for optimal performance
  • Air-free hydraulic piston and valve area delivers instant responsiveness and precise control
  • High-pressure nitrogen gas chamber with floating piston technology
  • Provides comfortable ride quality during normal driving conditions
  • Instant performance enhancement on demand during aggressive driving
  • Fade-free performance maintains consistency under varying conditions
  • Larger piston diameter compared to twin-tube designs for improved handling

The Gas-a-Just monotube design separates the hydraulic fluid from the nitrogen gas charge using a free-floating piston, preventing aeration and foam buildup that can diminish shock performance. This configuration ensures consistent damping force and eliminates the performance fade common in traditional twin-tube shocks, making it an ideal upgrade for enthusiast drivers and OE monotube replacement applications.

Easy ordering

PayPal checkout did not work.

I ordered front and rear master install gear sets for my jeep. I also ordered a rear carrier. My order was at a great price and gears were delivered promptly but i noticed the carrier was not with this order. So when i called the lady was nice and polite and informed me it could be 8 to 10 weeks before I received the carrier. I had done scheduled service work for my jeep. They canceled the carrier promptly. But it would be nice if there was a way to see what was in stock before ordering. I ended up ordering at summit racing and had the carrier in 2 days, it cost more but had to have it

So far, very easy. Fingers crossed order process completes seamlessly.

Received product fast was exactly what I needed thanks

Ordering On Line Was Easy! So Far, So Good.....

SO FAR SO GOOD

This was my first order through autoplicity but I doubt it's my last. They had the best price by far on the K & N air filter I was looking for. The price was right, the filter was packed well, and the shipping was fast. No hassle transaction. Great job autoplicity!

Autoplicity has the cheapest prices around and fast shipping. I will do business with them again in the future.

The best!

Great products and great prices! Highly recommend!
