Product Details

KYB Strut-Plus is the KYB product line focused on complete strut assemblies that combine OE-restoring suspension geometry with matched components. SR4101 is built to replace the front left suspension strut and coil spring assembly on Ford Escape, Mazda Tribute, and Mercury Mariner applications, helping return the vehicle to factory-style ride height and handling balance. This part cross-references Monroe Shocks & Struts (e.g., 171594, 181594) for the same application.

What It Helps Address

• Front-end sag or uneven ride height
• Excessive bounce, nose dive, or reduced damping control
• Loose or imprecise steering feel from worn strut components
• Suspension noise related to a fatigued strut and spring assembly
• Handling instability on Ford Escape, Mazda Tribute, or Mercury Mariner front suspension service
