Is this a KYB gas shock absorber?
Yes. The KYB Gas-a-just 5540019 is a high-pressure monotube gas shock that separates the gas and oil for fade-free operation and instant response.
What vehicles does the 5540019 fit?
It's a FRONT-position direct-fit for the 2014-2025 RAM 2500 and 2013-2018 RAM 3500. Check the Buyer's Guide tab to confirm the fit for your vehicle.
How much more damping does it provide?
KYB states the Gas-a-just adds up to 25% more damping over original-equipment shocks, with extra damping over OE for trucks that work, tow, and run larger, heavier tires and wheels.
How does the monotube design help ride quality?
It uses two chambers: an air-free hydraulic piston and valve area for control, plus a high-pressure nitrogen gas area with a floating piston for comfort during normal driving.
What are signs my shock may need replacing?
Excessive bouncing, nose-dive under braking, poor steering response, or fluid seepage can indicate a worn shock. Diagnose the cause before replacing.
