Product Details

The KYB Gas-a-Just 555056 is a high-performance monotube gas shock absorber engineered to deliver superior handling and control over traditional twin-tube designs. This advanced shock features a monotube construction that eliminates fade and provides instant response to changing road 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
  • Fade-free performance eliminates aeration issues common in twin-tube shocks
  • Automatically adjusts to performance demands without driver input
  • Comfortable ride quality during normal driving with instant firmness on demand
  • Higher gas pressure provides increased damping capability and vehicle control

The Gas-a-Just monotube design keeps the gas and oil separated by a floating piston, maintaining consistent damping performance under all driving conditions. This construction allows for better heat dissipation and more responsive handling compared to conventional shock absorbers, making it an excellent upgrade for drivers seeking improved vehicle dynamics and control.

Paid for UPS 2nd Day service on Wednesday afternoon... called Autoplicity about lack of shipping info on Thursday AM and was told the system takes 24 hrs to update. On Friday tracking put the shipment in the delivery location at 1:30am. UPS customer service advised they could have refunded shipping cost if I had shipped direct.... not sure how or why I would accomplish the task. UPS advised contacting the shipper to resolve the issue.. really? Product sat in the UPS delivery center until Monday AM and was delivered Monday PM. Product was installed in my tractor Monday evening.... now it has rained every day and I can't cut the field. Question is really, why offer 2 day service at a premium when no one does what they promise... Purchased these bearings at Autoplicity because of the 2 day service..... who dropped the ball? Most on-line retailers shipping options change if and when you are outside guidelines. That wasn't the case here.

Thank u

Fast service, good price!

Even though I checked the 20offshipping it did not apply it at checkout.
