KYB Suspension Shock Absorber P/N:555055

Description

Firm up every hauling and towing mile with the KYB Gas-a-just High Pressure Monotube Gas Shock, part number 555055 — a rear-position KYB shock absorber offered as an OE monotube replacement to help restore your truck's original ride control. It installs as a direct-fit replacement for the 2007-2024 Chevrolet Silverado 1500 and GMC Sierra 1500, the 2019 Chevrolet Silverado 1500 LD, the 2022 Chevrolet Silverado 1500 LTD, and the 2019 and 2022 GMC Sierra 1500 Limited; see the Buyer's Guide tab for engine-level fitment.

High-pressure monotube design: separates the gas and oil into two working chambers — an air-free hydraulic piston and valve area for control, plus a high-pressure nitrogen gas area with a floating piston for fade-free operation.
Triple chrome plated piston rod: since leaking fluid can cause shock failure, the ultra-smooth rod is designed to reduce seal wear.
Quick response: the higher gas pressure is designed to improve steering response.
Built for work: engineered for full-size GM trucks that work, tow, and run larger, heavier tires and wheels, and helps keep Electronic Safety Systems performing as designed.

Frequently Asked Questions

What vehicles does the KYB Gas-a-just 555055 shock fit?

It's a rear shock for the 2007-2024 Chevrolet Silverado 1500 and GMC Sierra 1500, the 2019 Silverado 1500 LD, the 2022 Silverado 1500 LTD, and the 2019 and 2022 GMC Sierra 1500 Limited. Check the Buyer's Guide for engine details.

What makes this a gas shock absorber?

The KYB gas shock absorber uses a high-pressure monotube design that separates gas and oil, with a high-pressure nitrogen chamber and floating piston for fade-free operation and instant response.

Is this a rear or front shock?

This 555055 is cataloged as a rear-position shock absorber for the listed applications.

How is the piston rod built?

It features an ultra-smooth triple chrome plated piston rod. Because leaking fluid can cause shock failure, the rod is designed to reduce seal wear.

Should I replace shocks in pairs?

This listing is for one shock. Replacing both sides on the same axle as a matched pair is recommended for even, balanced ride control if a worn shock is the cause of your issue.
