About this item

  • The correct, monotube-designed OEM replacement shock
  • Specifically calibrated to help restore the original handling and control characteristics of the Aspen and Durango
  • 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.

Made in Malaysia, which I feel better than than Chinese made but still prefer made in USA Monroe models. They are very skinny compared to Monroe. And after only 6 months of use, mainly highway, they are so soft that I am back to no shocks in front. Got Monro for the back and they’re just fine.

Easy to install, ride feels better but then again the originals they replaced are over 17 years old and have 120K miles on them.

I bought cheap shocks that actually broke after 3 months. Test snapped in half. Upgraded to these kyb and love the ride quality. I can feel the road. Excellent.

Greatly improved ride and comfort over stock shocks. Stops vehicle from bouncing after bumps and stops diving while braking and turning. Very easy to install. Will purchase again for other vehicles. Purchased with matching rear shocks.

Shocks are already install. And the ride it's smooth. It feel better than before. And the price was cheaper than the competition. Thank you amazon.

Best decision to make after researching options. Minimal loss to ride comfort while providing greatly increased performance over OEM shocks. Eliminated brake dive, wheel hop and quite a bit of body roll -- stiffer for towing (camper). Debated these against the Bilsteins and very glad I went with these. Admitted cost savings but the Bilsteins would have been harsher on ride quality. These are quality upgrades over OEM.2009 Chrysler Aspen 5.7L Hemi w/ Tow Package

Ride quality is a better and eliminates a majority of body roll. The installation was easy, and the parts came in quick. These shock absorbers are a great base replacement for the price.EDIT:passenger side went out after a month. and driverside is as spongey as ever after a month. waste of time and money.

A nice step up from stock. Ride is comfortable and steady. A great shock for a decent price for a truck that is not off-roaded except for travel on a gravel and snow covered roads. Would definitely buy again.
