Up to 25% More Control
With a faster response and up to 25% more damping over OE twin-tube designs, KYB Gas-a-Just shocks are a great way to give your vehicle additional handling and control capabilities.
For Larger Tires and Wheels
Larger, aftermarket wheels can add up to 25 pounds of additional weight to each corner. Original Equipment shocks and struts are designed for original tires and wheels, not larger, heavier ones. Gas-a-Just shocks include additional damping over OE design and work well with larger, heavier tires and wheels.
Increases Steering Response
Steering response is a critical part of vehicle safety. Worn and economy shocks can allow fluid to travel through the shock valves too quickly, this reduces overall steering response. KYB’s shock valves are designed to help restore steering response to what the vehicle manufacturer intended.
Improves Stopping Distance
Worn and economy shocks may not have enough damping to keep your vehicle level and in control when braking. They can allow weight to transfer too quickly, resulting in a vehicle that is harder to steer and doesn’t stop as designed. New KYB shocks will help hold down the rear of the vehicle when braking to reduce stopping distance and improve brake life.
Monotube Design
High pressure monotube design separates the gas and oil for fade free operation and instant response. This design works best on sports cars and on trucks and SUVs with higher roll center.
Increases Stability
With a faster response and additional damping, KYB monotube shocks provide more stability (especially vehicles with a higher center of gravity) when compared to traditional twin-tube shocks.

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 for vehicles that came equipped with a monotube shock, and as a performance upgrade on vehicles that came equipped from the factory with twin-tube shocks. The KYB Gas-a-Just has two separate working chambers: An air-free hydraulic piston and valve area for responsiveness and 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 high pressure monotube design responds instantly to conditions and driver inputs to deliver increased handling capabilities over twin-tube designs.

Monotube shocks have separate chambers for the nitrogen gas and hydraulic fluid, this eliminates aeration and foaming and helps maintain consistent damping force in all conditions.

Fluid leaking can be a cause of shock failure, the KYB Gas-a-Just has an ultra-smooth triple chrome plated chrome piston rod to reduce seal wear. The multi-lip, synthetic oil seal is engineered to keep fluid in and has a wiper to keep contaminates out of the oil.

The KYB Gas-a-Just is available for cars, trucks, vans and SUVs
