Product Details

The KYB Gas-a-Just 551118 is a high-performance monotube gas shock absorber designed to restore and enhance your vehicle's handling capabilities. This advanced shock features a monotube design that provides superior heat dissipation and consistent performance compared to traditional twin-tube shocks.

Key Features:

  • Monotube design with two separate working chambers for optimal performance
  • Air-free hydraulic piston and valve area delivers immediate responsiveness and precise control
  • High-pressure nitrogen gas chamber with floating piston provides adaptive damping
  • Comfortable ride quality during normal driving conditions
  • Instant performance enhancement when aggressive driving demands it
  • Superior fade resistance due to efficient heat dissipation
  • Direct OE replacement fitment for easy installation

The Gas-a-Just technology separates the hydraulic fluid from the high-pressure nitrogen gas using a floating piston, eliminating aeration and foam that can reduce shock performance. This design ensures consistent damping force throughout the shock's stroke, providing better vehicle control, reduced body roll, and improved stability during cornering and braking.

quick fast and easy

Great company to deal with. I placed an order with them (albeit an incorrect shipping address) and before you know it I'm expecting delivery in a very short amount of time. I also did have to call and attempt to correct my address error when the customer service rep let me know that all is well and set to be delivered to the correct address. I appreciate the fact that the gentleman on the other end of the phone was reassuring, courteous, and professional. I'd certainly do business with them again as the prices and customer service can't be beat!

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

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.
