Keep heavy-duty hauling under control with the KYB Gas-a-just High Pressure Monotube Gas Shock (P/N KG6001A), a front-position shock absorber that installs as a direct-fit replacement across a wide range of work trucks — the 1973-1989 Chevrolet C50 and C60, 1979-1989 GMC C6000, 1980-1989 Chevrolet B60, C70 and GMC B6000/C5000/C7000, 1985-1999 Chevrolet P30 and GMC P3500, 1993-1996 Chevrolet G30 and GMC G3500, and 1999-2000 Workhorse P32. See the Buyer's Guide tab for the full application and engine list.
This monotube design separates the nitrogen gas and hydraulic oil into two working chambers — an air-free hydraulic piston and valve area for responsiveness and control, plus a high-pressure nitrogen gas area with a floating piston — so it resists fade from aeration and responds instantly on demand.
- Up to 25% more damping: adds damping performance over original equipment shocks, with components and valving designed specifically for heavy-duty trucks.
- Built to work and tow: Gas-a-just monotubes add damping over the OE design for vehicles that work, tow, and run larger, heavier tires and wheels.
- Fade-free operation: high-pressure monotube design separates gas and oil for fade-free operation and instant response.
- Triple chrome-plated piston rod: an ultra-smooth triple chrome-plated rod helps reduce seal wear, since fluid leaking can be a cause of shock failure.
The higher gas pressure responds quickly to help improve steering response, and the Gas-a-just helps keep electronic safety systems performing as designed, since they depend on the suspension, brakes, and tires operating as the vehicle manufacturer intended.
