Keep your Ram planted and controlled with the KYB Gas-a-just Front Suspension Shock Absorber (MPN 5540019), a high-pressure monotube gas shock that drops in as a direct-fit front replacement for the 2014-2025 RAM 2500 and 2013-2018 RAM 3500 — see the Buyer's Guide tab for engine-level details. Its monotube design separates the gas and oil for fade-free operation and instant response, and the components and valving are designed specifically for Rams that work, tow, and run larger, heavier tires and wheels.
- High-pressure monotube gas design: separates gas and oil to resist aeration fade and deliver quick response.
- Triple chrome-plated piston rod: an ultra-smooth rod helps reduce seal wear, since fluid leaking can be a cause of shock failure.
- Higher gas pressure: designed to respond quickly to help improve steering response and add damping on demand.
- Up to 25% more damping over OE shocks: extra control for vehicles that work and tow, and helps keep Electronic Safety Systems performing as designed.
Signs your shocks may need replacing include excessive bouncing, nose dive under braking, or a loose, wandering feel. Shocks wear as a pair — replacing both front units together is recommended for balanced control.
