KYB Suspension Strut P/N:551118

Description

Bring firm, controlled damping back to the rear of your roadster with the KYB Gas-a-just Suspension Strut (MPN 551118), a high-pressure monotube gas strut offered as an OE monotube replacement for the 2006-2015 Mazda MX-5 Miata. If you're shopping for a KYB strut for the Miata's rear suspension, this is the correct monotube-designed OE replacement, built to help restore the car's designed control and handling.

Twin-chamber monotube design: an air-free hydraulic piston and valve chamber handles responsiveness and control, while a separate high-pressure nitrogen chamber with a floating piston supports a comfortable ride during normal driving and adds performance on demand.
Triple chrome-plated piston rod: the ultra-smooth rod is made to reduce seal wear, since leaking fluid can be a cause of shock failure.
Higher gas pressure: responds quickly and is designed to improve steering response.
Gas and oil separated: the high-pressure monotube layout keeps gas and oil apart for fade-free operation and instant response.

As a monotube OE replacement, the Gas-a-just is designed to restore the vehicle's original capabilities and helps keep electronic safety systems performing as designed, since those systems depend on the suspension, brakes and tires working as the manufacturer intended. This listing covers the rear position; struts wear together, so replacing both rear sides as a matched pair supports even, balanced ride control.

Frequently Asked Questions

What vehicle does the KYB 551118 strut fit?

It's an OE monotube replacement for the rear suspension of the 2006-2015 Mazda MX-5 Miata. See the Buyer's Guide tab to confirm the correct application for your car.

Is this a front or rear strut?

This is the rear suspension strut, cataloged for the rear position on the listed application.

What is a high-pressure monotube gas strut?

It uses a single tube with a high-pressure nitrogen gas chamber and a floating piston that separates the gas from the oil, giving fade-free operation and quick response.

Does it include a coil spring or mounting hardware?

This listing is for the Gas-a-just strut. A spring or mounting hardware isn't listed in the part facts, so confirm what your repair needs and source any additional parts as directed by the service procedure.

Should I replace both rear struts at the same time?

Struts wear together, so replacing both rear sides as a matched pair is recommended for even, balanced ride control, though it isn't strictly required.
