Product Details

The KYB Gas-a-Just 551104 is a high-performance monotube gas shock absorber engineered to deliver superior handling and responsiveness for demanding driving conditions. Unlike traditional twin-tube designs, this monotube configuration provides instant adaptability and fade-free performance throughout its service life.

Advanced Monotube Design:

  • Dual-chamber construction with separate hydraulic and gas chambers for optimal performance
  • Air-free hydraulic piston and valve area ensures precise responsiveness and control
  • High-pressure nitrogen gas chamber with floating piston design
  • Eliminates shock fade caused by aeration during extended use
  • Instantly adapts to changing road conditions and driving demands

Performance Benefits:

  • Enhanced vehicle stability during cornering and high-speed maneuvers
  • Improved steering response and road feedback
  • Reduced body roll and dive under braking
  • Comfortable ride quality during normal driving conditions
  • On-demand performance when aggressive driving is required

The Gas-a-Just monotube shock is ideal for drivers seeking improved handling characteristics, towing capability, and spirited driving performance while maintaining everyday drivability. The monotube design runs cooler and more consistently than twin-tube alternatives, making it an excellent choice for performance applications and vehicles that experience demanding use.

easy ordering. 15 secs and i was done.

Best price around! I can't believe the deal I got on my part for my Jeep Cherokee. Just waiting now for it to arrive in the mail.

Great to order from shipping was fast and just awesome service will order from here again

Very speedy and in excellent shape. Easy to install and only took minutes. Autoplicity in my book is a great place to shop. <br><br>-Jason Chance<br> Cape Fair, MO

Great prices and fast delivery. I ordered my cam+springs+phaser kit for my 2007 mustang, I found the best prices with Autoplicity. Strongly recommend and most certainly purchasing here again

Ordered Lucas gear oil and have to say the service is great and delivery was very quick. I will recommend Autoplicity for quality yet affordable prices. will do business with again!

Great customer service. Quick and fast service. Great product knowledge

My first order and I must say, very impressive! Awesome prices and super-fast shipping direct from the manufacturer. Couldn't ask for more! I will return.

I would definitely recommend Autoplicity. I ordered Thule bike racks (THU-518), and the products arrived in 2 days in perfect condition. Plus the prices (along with free shipping) were the best on the web.

Excellent price on name brand items, best prices for Bosch oxygen sensors.
