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.

The ride on these is so much smoother than the shocks I replaced. For these unibody cars you really want to stay away from air shocks. Can't be happier with this purchase.

Reemplacé mis viejos amortiguadores por estos y la verdad, el vehículo mejoró mucho en su comportamiento. adios a los ruidos y a la sensación de rebote contínuo en la parte trasera. Si tienes un Mopar A-Body de entre el 69-76, lo recomiendo al 100

These shocks stiffened up my vintage Plymouth nicely. I bought them through Just Suspension and their customer service is extraordinary. I would definitely recommend them.
