KYB Suspension Strut P/N:551605

Description

Comparing KYB strut plus options for your 2003-2007 Cadillac CTS? Reach for the KYB Gas-a-just High Pressure Monotube Gas Strut (P/N 551605), a FRONT monotube-designed OEM replacement offered to restore the vehicle's original capabilities and help bring back the designed control and handling of the Cadillac CTS.

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 that separates the gas and oil for fade-free operation and instant response.
Triple chrome-plated piston rod: because fluid leaking can be a cause of shock failure, the ultra-smooth triple chrome-plated rod is built to reduce seal wear.
Built for hard-working vehicles: designed for vehicles that work, tow, and run larger, heavier tires and wheels, with higher gas pressure that responds quickly to help improve steering response.
Supports electronic safety systems: helps keep the CTS's electronic safety systems performing as designed, since they depend on the suspension operating as the manufacturer intended.

Is this an OE replacement?

Yes. KYB offers the Gas-a-just as a monotube-designed OEM replacement intended to restore the vehicle's original capabilities.

Should I replace both front struts at the same time?

Replacing both front struts together as a matched pair is recommended for even, balanced handling and consistent ride quality.

What are signs my struts may need replacing?

Common signs include excessive bouncing, nose-diving when braking, poor handling, uneven tire wear, or fluid leaking from the strut. Diagnose the cause before replacing.
