Product Details

The KYB Gas-a-Just 553388 is a high-pressure monotube gas shock absorber designed to restore and enhance your vehicle's original handling capabilities. This performance-oriented shock provides superior damping control for drivers seeking improved responsiveness without sacrificing daily driving comfort.

Key Features:

  • Monotube design with two separate working chambers for optimized performance
  • Air-free hydraulic piston and valve area delivers immediate responsiveness and precise control
  • High-pressure nitrogen gas chamber with floating piston maintains consistent damping
  • Provides comfortable ride quality during normal driving conditions
  • Instant performance enhancement on demand during spirited driving
  • Direct OE monotube replacement for easy installation
  • Fade-resistant performance under demanding conditions

The Gas-a-Just monotube configuration eliminates aeration and foaming issues common in twin-tube designs, ensuring consistent shock performance. The high-pressure nitrogen charge keeps the oil and gas separated via a floating piston, maintaining optimal damping characteristics across varying temperatures and road conditions. Ideal for drivers who demand more from their suspension without compromising ride quality.

I ordered refill wiper blades for a Prius. However, they require bending the detents to fit the wiper assembly and the passenger side blade isn't stiff enough. It leaves about a two inch arc of moisture that isn't wiped off.

Will install part soon once I have all the needed hardware

quick and easy

Best prices around.

fast and easy,Great price

I'm not going to comment on a part until I've got it installed and road tested. Delivery is too soon for this survey. You should wait a week before sending.

Get what I ordered and it's well packaged and received on a timely basis.

Perfect!

I was very pleased with ordering experience on your website will use again for my parts needs

Found the price unbeatable after much research online. Wish it was a little faster turn around time (3 days), but overall I am happy with my purchase. The option of buying through Amazon was great!

Extremely Happy! Best price on the web, easy order tracking, if only all online orders from other sources were this easy. I ordered a component from another online retailer who showed parts "in stock" only to see my status as "sent to warehouse" and it was weeks. When Autoplicity shows "in stock" it really was and delivered right away.

They have easy forms and fair prices

Item shipped 5 days after order was placed. Worth the wait for the great price however. Order Number: 18722

I was little worried when I made an order, because the price was too good to be true, and Autoplicity was new to me.<br>However, Autoplicity took only a business day to ship my item.<br>The item has been delivered, and I'm very happy with Autoplicity and the item itself.<br><br>Thank you Autoplicity for the great price and fast shipping!!!

Very pleased with the service and quick shipping. Checked out through Amazon payments without any issues. Item ordred was the Hella Supertone Horns. Arrived in original box and packaging. Will not hesitate to order from Autoplicity in the future

great price and order process was very simple and easy

quick and easy shopping. very good. The only complaint I have is it took too long to receive my order. I ordered Wilwood brakes from California and it took 4 days. It took 10 days to receive my brake master cylinder from Autoplicity.com. I think that is

Best deal I've seen on that resonator .

Better prices and even better service. Will do business with again.

Went to ebay, amazon, and summit racing looking for this part and finally found it here after looking on this site for about 10 seconds.
