Rear Shock Absorber for 2004-2008 Ford F-150 & More - KYB KG5193

Firm up a working truck's rear ride with the KYB Gas-a-just Shock Absorber (KG5193), a high-pressure monotube gas shock that installs as a direct-fit rear replacement for the 2004-2008 Ford F-150 and the 2006-2008 Lincoln Mark LT. This KYB shock absorber uses a monotube design with two separate working chambers — an air-free hydraulic piston and valve area for responsiveness and control, plus a high-pressure nitrogen gas area with a floating piston — so it never experiences fade due to aeration.

• Up to 25% more damping: Adds up to 25% more damping performance over original equipment shocks, with components and valving designed specifically for Ford trucks.
• Built to work and tow: The Gas-a-just monotube adds damping over the OE design for vehicles that work, tow, and run larger, heavier tires and wheels.
• Fade-free, quick response: The high-pressure monotube separates the gas and oil for fade-free operation and instant response, and the higher gas pressure helps improve steering response.
• Reduced seal wear: An ultra-smooth triple chrome-plated piston rod reduces seal wear, since fluid leaking can be a cause of shock failure.

KYB notes the Gas-a-just also helps keep Electronic Safety Systems performing as designed, since those systems depend on the suspension, brakes, and tires operating as the vehicle manufacturer intended. Sold individually; replacing both rear shocks together as a matched pair is recommended for even, balanced ride control. See the Buyer's Guide tab for engine-level fitment.
