Firm up ride control on your classic GM truck with the KYB shock absorber KG5409, a High Pressure Monotube Gas Shock from KYB's Gas-a-just line. It installs in the FRONT position and is a direct-fit replacement for a wide range of Chevrolet and GMC trucks, vans and Suburbans — including the 1969-1974 Chevrolet Blazer, 1975-1986 Chevrolet C10, 1975-1995 Chevrolet G10 and 1979-1995 GMC G1500, plus many more. See the "Vehicles it fits" section for the full list.
Monotube gas design: the high-pressure monotube separates the gas and oil into two working chambers for fade-free operation and instant response, avoiding the aeration of a traditional twin-tube shock.
Built for GM trucks: the components and valving are designed specifically for GM trucks and add up to 25% more damping over the original-equipment shock, suited to vehicles that work, tow, and run larger, heavier tires and wheels.
Responsive control: higher gas pressure is designed to improve steering response, and an ultra-smooth triple chrome-plated piston rod helps reduce seal wear. By keeping the suspension working as intended, it helps electronic safety systems perform as designed.

Frequently Asked Questions
Is the KYB gas shock absorber KG5409 a front or rear shock?
It is cataloged for the FRONT position on the listed applications. Confirm fitment for your specific vehicle in the "Vehicles it fits" section.
What makes a monotube gas shock different from a twin-tube?
The high-pressure monotube design separates the gas and oil into two chambers, which is designed for fade-free operation and instant response and avoids aeration common to twin-tube shocks.
How much extra damping does the Gas-a-just add?
KYB states the Gas-a-just adds up to 25% more damping performance over the original-equipment shock, with components and valving designed specifically for GM trucks.
Does it suit trucks that tow or run larger tires?
Yes. The added damping over the OE design is intended for vehicles that work, tow, and run larger, heavier tires and wheels.
What is the triple chrome-plated piston rod for?
Fluid leaking can cause shock failure, so the ultra-smooth triple chrome-plated piston rod is designed to reduce seal wear.
