Strut-Plus Product Line

KYB Strut-Plus assemblies are built as complete replacement units that pair a KYB strut with a vehicle-specific coil spring. For the BMW X3, that means the spring rate and ride height are selected around vehicle attributes and corner weights to help return the suspension to OE-level geometry and feel. Part number SR4674 is part of this Strut-Plus line.

Detailed Description

As an original equipment supplier, KYB builds the Strut-Plus SR4674 with the BMW X3’s suspension requirements in mind. The assembly is engineered to restore handling and control by replacing the worn strut and spring together, rather than servicing those components separately. This helps maintain proper front-end support, steering response, and ride height on 2004-2010 BMW X3 models. If you are searching for a BMW X3 front left strut assembly or a KYB SR4674 replacement strut and coil spring assembly, this part matches that application.

What It Helps Address

• Front-end sag or reduced ride height
• Excessive bounce or poor damping control
• Loose or inconsistent steering feel
• Uneven suspension support on the front left corner
• Replacement needs for a worn BMW X3 strut assembly

Installation Notes and Tips

Install on the front left position only. Because this is a complete strut and spring assembly, it simplifies replacement compared with rebuilding the unit piece by piece. Verify vehicle fitment by year, make, model, and position before installation. After installation, a wheel alignment is recommended to confirm proper suspension geometry.

Quality Assurance

KYB is an original equipment supplier, and the Strut-Plus SR4674 is built to restore OE-style ride height and control characteristics for the BMW X3. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
