KYB 5550011 Suspension Strut - Front

KYB Gas-a-Just Front Strut for Frontier

The KYB Gas-a-just 5550011 is a front suspension strut for the 2005-2021 Nissan Frontier. It is built as an OE monotube replacement to restore factory ride control, with a design that separates hydraulic response from high-pressure gas support for consistent handling.

Compatible with Nissan Frontier front suspension service, this strut is a direct-fit option for drivers replacing worn OE-style components. The Gas-a-just line focuses on responsive damping and controlled ride quality for everyday driving.

Product Details

The KYB Gas-a-just 5550011 is engineered for the front suspension of the Nissan Frontier and uses a monotube layout that separates the hydraulic working area from the nitrogen gas chamber. That construction supports quick response, stable damping, and consistent control during normal driving and under higher-demand conditions. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Fits 2005-2021 Nissan Frontier, front. Use this front strut when replacing a worn OE-style unit on Frontier models that need restored ride height control, steering stability, and suspension damping performance. The KYB 5550011 is a practical replacement for front suspension service on the Nissan Frontier across the listed model years.

Common Issues This Part Can Address

• Excessive front-end bounce after bumps
• Reduced steering control or vague road feel
• Uneven damping from a worn front strut
• Noisy or unstable front suspension operation
• Loss of ride consistency on daily driving routes

Installation Notes and Tips

Verify the lower mount type E2 (14.2x42) and upper mount type S1 (12MM) before installation. Confirm compressed length, extended length, and stroke length against the original strut to ensure proper suspension travel. Professional installation and a wheel alignment are recommended after front strut replacement on the Nissan Frontier.
