Firm up front-end control and keep damping fade-free with the KYB Gas-a-just Monotube Shock Absorber KG5409, a high-pressure gas front shock built for classic GM trucks, vans and SUVs. It installs in the front position on applications including the 1969-1974 Chevrolet Blazer, 1975-1986 Chevrolet C10, 1963-1974 Chevrolet C10 Pickup, 1975-1995 Chevrolet G10/G20/G30, 1970-1982 GMC Jimmy, and 1967-1974 GMC C15/C1500 Pickup — see the Buyer's Guide tab for the full 83-application list and engine details.

  • High-pressure monotube design: separates the gas and oil into distinct chambers for fade-free operation and instant response.
  • Air-free hydraulic action: a nitrogen-charged floating piston keeps the valving aerated-free, so it does not fade during hard use.
  • Up to 25% more damping: adds up to 25% more damping performance over original-equipment shocks, with components and valving designed specifically for GM trucks that work, tow, and run larger, heavier tires and wheels.
  • Triple chrome-plated piston rod: an ultra-smooth rod helps reduce seal wear, since fluid leaking can be a cause of shock failure.

The higher gas pressure helps improve steering response and, per KYB, helps keep Electronic Safety Systems performing as the vehicle manufacturer designed. Sold individually; replace shocks as an axle pair for balanced ride control.

Frequently Asked Questions

Where does the KG5409 mount?

It is a front-position shock absorber. Sold individually, so order two to replace both front shocks together for balanced damping.

What makes the Gas-a-just monotube different from a twin-tube shock?

Its high-pressure monotube design keeps the gas and oil in separate chambers, so the valving stays air-free and resists fade during hard or towing use.

Will this fit my vehicle?

It fits many 1963-1999 Chevrolet and GMC trucks, vans and SUVs. Check the Buyer's Guide tab for the full 83-application list and confirm your exact model and year.

How much extra damping does it provide?

KYB states it adds up to 25% more damping performance over original-equipment shocks, with components and valving designed specifically for GM trucks.

What are signs a shock may need replacing?

Excessive bouncing, nose dive under braking, poor ride control, or fluid leaking from the shock body are common signs. Diagnose the cause before replacing.
