What is the KYB gas shock absorber KG6412?
It's a KYB Gas-a-just High Pressure Monotube Gas Shock — a front shock absorber that separates gas and oil in a monotube design for fade-free operation and instant response.
What vehicles does this KYB shock absorber fit?
It's a front direct-fit for the 1993-1996 Chevrolet G30 and GMC G3500, the 1985-1999 Chevrolet P30 and GMC P3500, and the 1999-2000 Workhorse P32. Check the Buyer's Guide tab.
How is the KYB Gas-a-just different from a twin-tube shock?
Its monotube design keeps the high-pressure nitrogen gas and hydraulic oil in separate chambers, which resists aeration and helps avoid fade during demanding use.
Does this KYB gas shock absorber work for towing or heavy loads?
Its valving is designed for Heavy Duty trucks and adds up to 25% more damping over OE shocks for vehicles that work, tow, and run larger, heavier tires and wheels.
Should I replace shocks in pairs?
Replacing both sides on an axle together is recommended for balanced ride control and even wear. This listing is for one shock; order the quantity your vehicle requires.
