KYB Suspension Shock Absorber P/N:554379

$80.99

Description

Steady the rear of your minivan with the KYB Gas-a-just shock absorber (P/N 554379), a high-pressure monotube gas shock that drops in as the correct monotube-designed OE replacement for the rear axle of the 2011-2012 Chrysler Town & Country and 2009-2012 Dodge Grand Caravan. This KYB shock absorber separates the gas and oil so it resists the fade that aeration causes in traditional twin-tube designs, delivering responsive control and instant response.

Monotube gas design: 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 for a comfortable ride during normal driving.
Built for working vans: Gas-a-just monotubes are designed for vehicles that work, tow, and carry larger, heavier tires and wheels.
Triple chrome-plated piston rod: An ultra-smooth chromed rod reduces seal wear, since fluid leaking can be a cause of shock failure.
Steering feel: The higher gas pressure responds quickly to help improve steering response and helps restore the designed control and handling.

KYB also notes the Gas-a-just helps keep Electronic Safety Systems performing as designed, since those systems depend on the suspension, brakes, and tires. Sold individually; for even, balanced ride quality, replace both rear shocks as a matched pair.

Buyer's Q&A

Frequently Asked Questions

What vehicles does the KYB 554379 shock fit?

It is a rear-axle replacement for the 2011-2012 Chrysler Town & Country and the 2009-2012 Dodge Grand Caravan. See the "Vehicles it fits" section to confirm your exact vehicle.

Is this a monotube or twin-tube shock?

It is a high-pressure monotube gas design. It separates the gas and oil into two chambers, which resists the fade that aeration can cause in traditional twin-tube shocks.

Do I need to replace both rear shocks?

Shocks are sold individually, so this listing is for one. For even, balanced ride quality it's best practice to replace both rear shocks together as a matched pair.

Why does the KYB gas shock absorber have a chrome-plated rod?

Fluid leaking can be a cause of shock failure. The Gas-a-just uses an ultra-smooth triple chrome-plated piston rod to reduce seal wear.

What are signs my rear shocks may need replacing?

Common signs include excessive bouncing after bumps, nose dive, body sway, uneven or cupped tire wear, and visible fluid leaking from the shock body. Diagnose the cause before replacing.
