Detailed Description

KYB SR4186 is designed for the 2003-2007 Nissan Murano front left suspension position. The assembly uses a KYB strut matched with a high-carbon steel coil spring to help restore ride height within OE specifications while supporting handling and control. Because the strut assembly also serves as a steering pivot and load-bearing suspension component, correct replacement is important for consistent road feel and alignment behavior. This part cross-references Monroe Shocks & Struts (e.g., 172268, 182268) for the same application.

For buyers searching for a 2003 Nissan Murano front left strut assembly, a 2004-2007 Nissan Murano suspension strut and coil spring assembly, or KYB Strut-Plus SR4186 replacement parts, this unit is built for direct application-specific service.

What It Helps Address

• Excessive front-end bounce or poor damping control
• Uneven ride height at the front left corner
• Loose or unstable steering feel
• Noise or wear associated with a fatigued strut assembly
• Suspension performance issues after original equipment wear

For 2003-2007 Nissan Murano front left suspension service, SR4186 is a direct-fit assembly designed to simplify replacement.
