About this item

  • Adds up to 25% more damping performance over original equipment shocks
  • Components and valving designed specifically for classic Mopars
  • High gas pressure design provides instant, extra control
  • monotube design outperforms all other standard shock absorbers
  • Unique, air-free, hydraulic unit eliminates performance fade


The KYB Gas-a-Just monotube shock absorber has additional performance advantages over the traditional twin-tube design: It can instantly, automatically adjust to your performance needs and never experiences fade due to aeration. The Gas-a-Just is available as an OE monotube replacement and as an OE twin-tube performance upgrade. The KYB Gas-a-Just has two separate working chambers: An air-free hydraulic piston and valve area for responsiveness & control, and a second high-pressure nitrogen gas area with a floating piston that provides a comfortable ride during normal driving and adds instant performance on demand.

73 Sebring all around shock replacement. Great ride, fit perfectly, easy install at a great price. Got tired of leaky air lines on the rear shocks.

Excellent product though there were some fitment questions. I emailed tech support at KYB with some questions which they answered within an hour of me sending my inquiry. Information made it possible to fabricobble a sleeve for the lower mounting point and properly align the shocks at install (long story, previous owner handiwork).Can’t yet speak to ride quality since the car is not yet running.....but it is getting closer

Great improvement over regular oil filled shocks. My Road Runner rides better. Handles better. No more float.

Easy to install, bushings fit well (rear), great ride feel. Just be careful to have shock aligned into top mount first and close to bottom mount stud before removing the mesh compression device as gas pressure causes shock to expand/lengthen quickly.

Gas-a-Just shock use higher gas pressure to keep your tires glued to the road. The velocity sensitive valving adjusts to road conditions for maximum comfort in any situation.
