Product Details

The KYB Gas-a-Just 554373 is a high-performance monotube gas shock absorber engineered to deliver superior handling and fade-free performance. Unlike traditional twin-tube designs, this monotube shock features a sophisticated two-chamber system that provides both responsive control and ride comfort.

Advanced Monotube Design Benefits:

  • Instant automatic adjustment to changing road conditions and performance demands
  • Fade-free performance that eliminates aeration issues common in twin-tube shocks
  • Air-free hydraulic piston and valve chamber for precise responsiveness and control
  • High-pressure nitrogen gas chamber with floating piston technology
  • Comfortable ride quality during normal driving with instant performance on demand
  • Superior heat dissipation through larger diameter body design

The Gas-a-Just monotube technology separates the hydraulic fluid from the high-pressure nitrogen gas using a floating piston, ensuring consistent damping performance under all driving conditions. This design makes the 554373 an excellent choice for drivers seeking enhanced vehicle control, reduced body roll, and improved stability without sacrificing ride comfort.

Very good.

Had what I needed at a decent price and it arrived in a few days.

Best prices I've ever seen! I didn't install the parts yet so it's hard to comment on the quality yet.

Would be 5 star if package wasn't bent in shipping. However customer service and refund were prompt and courteous. Will recommend and shop with them again.

great customer service

Quick, easy, and fast delivery

so far so good.. hope it ships asap : ) thanks.

Good fast shipping. Easy ordering.

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>

Good

I am glad I found Autoplicity! Great prices, fast shipping, and excellent customer service. Already looking at other items to purchase from them. I highly recommend using Autoplicity!

I have to say I was skeptical at first because autoplicity's price beat everyone by so much! Then I estimated my shipping charges with their system and that too was real cheap for this heavy item I ordered! I ordered it on Sunday and it showed up on Tuesday afternoon! So exceptional pricing meets exceptional shipping and my item is the real thing for a lot less leaves me completely satisfied with this company! I will be recommending them to my friends and family, thanks!

Very satisfied. Good price and quick delivery.

I am so glad i found Autoplicity (searching Google). They saved me $100 over ALL the other online outlets, and gave me great customer service to go along with it.

The price is right but shipping cost is high. I bought a transmission seal for $12.91 and shipping was $13.31. The box it shipped in was about 10 times bigger than the part itself. Reduce the box and reduce my shipping cost please ! Else than that the part was in good condition, it was packed right and shipping time was reasonable.
