Product Details

The KYB Gas-a-Just 555607 is a high-performance monotube shock absorber engineered to deliver superior handling and responsiveness compared to traditional twin-tube designs. This advanced shock absorber features a unique dual-chamber design that eliminates fade and provides consistent performance under all driving conditions.

Key Features:

  • Monotube design with two separate working chambers for optimal performance
  • Air-free hydraulic piston and valve area ensures precise control and immediate responsiveness
  • High-pressure nitrogen gas chamber with floating piston technology
  • Automatically adjusts to changing road conditions and performance demands
  • Fade-free operation eliminates performance loss from aeration
  • Provides comfortable ride quality during normal driving with instant performance on demand
  • Available as direct OE monotube replacement or performance upgrade for OE twin-tube applications

The Gas-a-Just monotube design separates the hydraulic fluid from the nitrogen gas charge, preventing aeration and ensuring consistent damping force throughout the shock's stroke. This results in improved vehicle stability, reduced body roll, and enhanced steering response for drivers who demand more from their suspension system.

I really like the pay with Amazon feature, hope the shipping and packaging is as good!

Ordered a couple of items. The first was a air intake kit. I had put in all my info for my truck and chose one from the list to order. Won't fit. Called to tell them and they asked if I had called manufacturer...ummm no. Said I needed to contact them to verify wrong part. They were closed, so went to website. The part they sent me was a universal fit- for cars, not trucks, but did find right model- $90 more. Called back autoplicity and was told I need to go through email to get an RA# to return wrong part- site says I can call. Been on hold for over 20 mins and still waiting. Hope the Nerf bars I ordered fit! Update- they called me back, got my RA#. Very pleased with how Nick handled things- it was what I expected the first time. He verified the NERF bars will fit and will be changing the website so the universal intake does not show on list for vehicles with larger air outlets. Changing my rating to show my satisfaction with how it was eventually handled.

Lowest prices of what I was looking for and super fast shipping!!

Product was a good price, fast shipping and great costumer service! will do business again!

"Customer service was very helpful, very good prices. On its way the next day."
