Product Line Details

KYB Strut-Plus combines a KYB Excel-G strut with a matched coil spring and OE-focused assembly design. The line is built for drivers who need a front suspension strut and coil spring assembly that restores factory ride characteristics without changing the vehicle’s original suspension geometry.

Detailed Description

Part number SR4102 is built for front suspension service on 2005-2008 Chevrolet Uplander, 2005-2007 Buick Terraza, and 2005-2007 Saturn Relay models. KYB uses OE-restoring strut tuning and a spring matched to the application to help return the vehicle to proper stance, steering feel, and stability. This part cross-references Monroe Shocks & Struts (e.g., 172231, 182231) for the same application.

What It Helps Address

• Sagging front ride height
• Excessive bounce or poor damping control
• Reduced steering stability during braking or cornering
• Uneven front suspension response from worn strut components
• Suspension wear that can affect ESC and ABS system behavior

Installation Notes and Tips

Install SR4102 on the front position only and follow the manufacturer’s instructions for replacing the suspension strut and coil spring assembly. Because this is a pre-assembled unit, it is suited to professional suspension service where exact fitment and OE-style ride height restoration are priorities. Verify vehicle application by year, make, model, and front position before installation.

Quality Assurance

KYB is an original equipment supplier, and the Strut-Plus line is engineered to meet OE-style ride and handling expectations for the listed applications. The SR4102 is assembled in the USA and built with application-specific damping and spring rates for consistent front suspension performance.
