Product Details

The KYB Gas-a-Just monotube shock absorber delivers superior performance and durability through its advanced engineering design. Unlike traditional twin-tube shocks, this monotube configuration provides instant response and fade-free performance in all driving conditions.

Key Features:

  • Monotube design with two separate working chambers for optimal performance
  • Air-free hydraulic piston and valve area ensures precise responsiveness and control
  • High-pressure nitrogen gas chamber with floating piston technology
  • Eliminates shock fade caused by aeration for consistent damping
  • Automatically adjusts to driving demands without manual intervention
  • Provides comfortable ride quality during normal driving with instant performance when needed
  • Enhanced heat dissipation compared to twin-tube designs

The Gas-a-Just design separates the hydraulic fluid from the nitrogen gas using a floating piston, preventing fluid aeration and maintaining consistent damping characteristics. This makes the KG5521 ideal for drivers seeking improved handling, reduced body roll, and responsive suspension performance without sacrificing everyday ride comfort.

I recently ordered 2 Borla Dual Round Intercooled Tips from Autoplicity.com for one reason and reason only...their prices can not be beat! No where else online can anyone match them! <br>

Best prices, fast shipping, good service. Thank you!

Was looking online for the best price on a part and found that autoplicity had the lowest price and free shipping on it. I ordered it and it was shipped the next day along with tracking number. I will be ordering a few more parts from autoplicity. Order Number: 27769

Price is the lowest price you can get anywhere. Customer service goes the extra mile helping me with my oder. Delivery was fast and products were as advertised. I will definitely order from Autoplicity again.

The cheapest price on the net and very fast shipping. I received my items in 3 days and they were delivered on a Saturday to make things even better. <br><br>Will be using these guys again real soon.

I have placed orders with Autoplicity 3 times in the last 2 months, and have received excellent delivery, pricing and customer service in every instance. Thanks!

Great products, great prices, excellent communication!

** Update 4/18/2012<br>Everything arrived in several different shipments. I did experience a problem with some FelPro Headbolts that I had ordered. I ordered two and only received one, but after a short phone call with Paul from shipping, the problem was fixed and my second set of bolts were shipped.<br><br>They had the cheapest price that I could find on several products. I did not like the order confirmations on there website as I had to copy and paste to search for my tracking number. I am supposed to receive my order today and I am scared because the two weights do not match up. Autoplicity says 37.7 pounds and fedex says 3.8 pounds. Maybe there is more than one tracking number and I just do not know.
