Product Details

KYB Strut-Plus SR4215 combines a KYB strut and coil spring into a complete front suspension assembly for the driver-side front corner. KYB designs this line around original equipment requirements, using damping control and spring rates selected to help restore handling, control, and ride height on the Nissan Sentra. The Strut-Plus line is built for exact fitment and side-specific application, making it a practical choice for a 2007-2012 Nissan Sentra front left strut replacement.

This part cross-references Monroe Shocks & Struts (e.g., 172379, 182379) for the same application.

Common Issues It Can Address

• Front-end sag or reduced ride height
• Excessive bounce or poor damping control
• Loose or unstable steering feel
• Uneven handling after strut wear
• Noise or harshness from a worn suspension strut assembly

Installation Notes

Install on the front left position only and follow the vehicle manufacturer’s instructions for strut and coil spring assembly replacement. Verify side-specific fitment before installation on a 2007-2012 Nissan Sentra. Because this is a pre-assembled suspension strut and coil spring assembly, it is intended to simplify professional replacement while maintaining OE-style geometry.

Quality Assurance

KYB is an original equipment supplier, and the Strut-Plus line is engineered around OE restoring specifications for ride height, handling, and control. SR4215 is assembled in the USA and built with application-specific components selected for the listed Nissan Sentra fitment.
