KYB Suspension Shock Absorber P/N:5550036

$99.99

Description

Keep your truck's rear end planted and responsive with the KYB Gas-a-just Monotube Gas Shock Absorber (MPN 5550036), a rear-position, high-pressure monotube gas shock. It's a direct-fit replacement for the 2019-2021 Chevrolet Silverado 1500, 2022 Chevrolet Silverado 1500 LTD, 2019-2021 GMC Sierra 1500, and 2022 GMC Sierra 1500 Limited — including the Silverado 1500 Trail Boss and GMC Sierra 1500 AT4 w/ Factory Lift.

Monotube gas design: High-pressure monotube construction separates the gas and oil for fade-free operation and instant response, so it never experiences fade due to aeration.
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 for comfort during normal driving and added performance on demand.
Quick steering response: The higher gas pressure responds quickly to help improve steering response and helps keep Electronic Safety Systems performing as designed.
Triple chrome-plated piston rod: An ultra-smooth triple chrome-plated rod reduces seal wear, since fluid leaking can be a cause of shock failure.

The KYB Gas-a-just is designed as the correct monotube OEM replacement to help restore the intended control and handling of these trucks.

Frequently Asked Questions

What position does this shock absorber install in?

This is a rear-position monotube gas shock absorber for the listed Silverado 1500 and Sierra 1500 applications.

Which vehicles does the KYB 5550036 fit?

It fits the 2019-2021 Chevrolet Silverado 1500, 2022 Chevrolet Silverado 1500 LTD, 2019-2021 GMC Sierra 1500, and 2022 GMC Sierra 1500 Limited. See the Buyer's Guide tab to confirm your vehicle.

What makes a monotube gas shock different from a twin-tube?

The high-pressure monotube design separates the gas and oil in a single tube for fade-free operation and instant response, and it won't fade due to aeration.

Should I replace shocks in pairs?

This shock is sold individually. Replacing the rear pair together is a good practice for balanced ride and handling; order two for a complete rear replacement.

What is the triple chrome-plated piston rod for?

The ultra-smooth triple chrome-plated rod reduces seal wear. Since leaking fluid can be a cause of shock failure, this helps protect the seal over time.
