Product Details

KYB Strut-Plus is part of KYB’s Strut-Plus line, which combines an OE-style strut with a matched coil spring assembly for direct replacement service. As an original equipment supplier, KYB builds this assembly to match the vehicle’s suspension geometry and restore the handling and control expected from the factory setup. This part number, SR4646, is listed for the front right position on 2007-2008 INFINITI G35, 2011-2012 INFINITI G25, 2009-2013 INFINITI G37, and 2015 INFINITI Q40. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Sagging front ride height
• Loose or inconsistent front-end handling
• Worn strut performance at the front right corner
• Reduced steering stability during normal driving
• Suspension noise or harshness associated with worn strut components

Installation Notes

Fits 2007-2008 INFINITI G35, front right, without 4 Wheel Steering. Fits 2011-2012 INFINITI G25, front right. Fits 2009-2013 INFINITI G37, front right. Fits 2015 INFINITI Q40, front right. Verify the vehicle’s suspension configuration and position before installation. Because this is a complete strut and spring assembly, it is suited for replacing a worn front right unit without transferring the original spring.

Quality Assurance

KYB manufactures this Strut-Plus assembly as an OE-oriented replacement using a strut and spring combination developed to restore factory ride height and suspension behavior. The design reflects KYB’s role as an original equipment supplier for suspension components.
