KYB Suspension Shock Absorber P/N:KG54312

Firm up the rear ride of your truck with the KYB Gas-a-just Suspension Shock Absorber KG54312, a high-pressure monotube gas shock that installs as a direct-fit rear replacement for the 1997-2003 Ford F-150 and the 2004 Ford F-150 Heritage. See the Buyer's Guide tab for engine-level fitment.

• Monotube gas design: High-pressure design separates the gas and oil for fade-free operation and instant response, with no aeration fade like a traditional twin-tube.
• Two working chambers: An air-free hydraulic piston and valve area handles responsiveness and control, while a high-pressure nitrogen chamber with a floating piston supports a comfortable ride during normal driving.
• Triple chrome-plated piston rod: Since leaking fluid can cause shock failure, the ultra-smooth rod is designed to reduce seal wear.
• Built for the F-150: Components and valving designed specifically for Ford F-150s add up to 25% more damping over OE shocks — extra control for trucks that work, tow, and run larger, heavier tires and wheels.

The higher gas pressure is designed to sharpen steering response, and KYB engineers the Gas-a-just to help keep Electronic Safety Systems performing as intended. Sold individually; replacing both rear shocks together as a pair is recommended for balanced ride and handling.
