About this item

  • Provides up to 25% more damping control over original equipment shocks
  • Gas-a-Just reacts to load changes and adds instant responsiveness on trucks
  • High gas pressure design is perfect for hauling heavy loads
  • monotube design outperforms all other standard shock absorbers
  • Unique, air-free, hydraulic unit eliminates performance fade


The KYB Gas-a-Just monotube truck shock absorber has additional performance advantages over the 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.

I put these on the front of my 1989 LWB Montero, it also had KYBs on it before and they lasted a long time, never actually failing but they did get loose, which is why I decided to replace them again with KYBs, the ride is smooth yet grippy, it has a good balance of on and off road capability. It greatly reduced front pitch when hard breaking and increased the front handling very nicely.Off the road it nicely smooths out bumps while maintaining contact with the ground.
