KYB Suspension Shock Absorber P/N:5550008

Firm up the rear of your truck with this KYB shock absorber, part number 5550008 — a high-pressure monotube gas unit that installs as a direct-fit rear replacement on the 2017-2024 Nissan Titan. This is the KYB Gas-a-just monotube design, which separates the gas and oil into two 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 that adds performance on demand.

• Monotube gas construction: the high-pressure design separates gas and oil for fade-free operation and instant response, and does not experience fade due to aeration.
• Up to 25% more damping: adds up to 25% more damping performance over original-equipment shocks, with extra damping over the OE design for vehicles that work, tow, and run larger, heavier tires and wheels.
• Titan-specific tuning: components and valving designed specifically for the Nissan Titan; the higher gas pressure is designed to improve steering response.
• Triple chrome-plated rod: an ultra-smooth triple chrome-plated piston rod helps reduce seal wear, since fluid leaking can be a cause of shock failure.

KYB notes the Gas-a-just helps keep electronic safety systems performing as designed, since those systems depend on the suspension, brakes, and tires operating as the vehicle manufacturer intended.
