Product Details

The KYB Gas-a-Just KG54309 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 provides instant automatic adjustment to changing driving conditions without experiencing performance fade due to aeration.

Advanced Monotube Design:

  • Separate dual-chamber construction with air-free hydraulic piston and valve area for precise responsiveness and control
  • High-pressure nitrogen gas chamber with floating piston separates oil from gas to eliminate aeration and prevent fade
  • Monotube design dissipates heat more efficiently than twin-tube shocks for consistent performance
  • Instant automatic adjustment from comfortable cruising to aggressive handling on demand
  • Larger piston diameter provides increased control and stability

Performance Benefits:

  • Restores original handling and control while providing enhanced performance capability
  • Reduces body roll, nose dive during braking, and squat during acceleration
  • Maintains comfortable ride quality during normal driving conditions
  • Ideal for trucks, SUVs, and performance vehicles that require improved handling
  • Compatible with lifted or lowered vehicles

The KYB Gas-a-Just monotube shock is the perfect upgrade for drivers seeking improved vehicle control, reduced body motion, and fade-free performance without sacrificing ride comfort.

Excellent service and fast shipping. A seller I would do business with again.

I ordered an AEM intake for my F-150 on Christmas day and received it on the 29th. I would absolutely recommend this site to anyone looking for car parts - they had the lowest price by far and shipped fast. Great job!

Best price ever, easy to order

Nice site

very good low price, had a slight issue but customer service was amazing,. i would recommend AutoPlicity to anyone because of that, good prices, good customer service,. (meaning trust worthy) why not :). A+++ Service will buy from again!

Great price and quick shipping!

Lowest price on the Internet, good packaging and fast shipping.

Excellent service!!!! Ordered another part from one of those big chain stores three days earlier and got your part one day sooner than theirs. Thanks. Excellent customer service. Wouldn't hesitate to use you again.

Great product and speedy service!

Couldn't be more happy with my product. I ordered from Autoplicity because they were the cheapest price around and I received my order within 5 days. I have installed the cold air intake and couldn't believe all the extra power. I am very pleased with the entire transaction.
