Westar ST-7906 Coil Spring Insulator - Front Upper

Coil Spring Insulator Overview

Westar ST-7906 is a coil spring insulator for suspension applications that need controlled movement, noise isolation, and a secure interface between the strut and body. It is built with application-specific materials and a protective finish to support long-term service.

Key Features

• Provides a pivot point that lets the suspension rotate within proper operating dynamics.
• Helps lock the strut and body together for stable suspension assembly function.
• Includes noise-dampening properties to reduce road vibration transfer into the cabin.
• Application-specific construction and finish support durability and appearance.

Detailed Description

Westar ST-7906 is a suspension coil spring insulator engineered for the front upper position on select Ford Escape, Mazda Tribute, and Mercury Mariner models. By isolating contact points and managing movement at the strut assembly, it helps maintain steering response and reduce wear on related suspension components. This part number, ST-7906, is also cross-referenced to Monroe Shocks & Struts 907906 and Anchor 707906 for the same application.

For Ford Escape, Mazda Tribute, and Mercury Mariner suspension service, ST-7906 provides a direct-fit replacement path for the specified front upper application. The design focuses on controlled rotation, secure assembly retention, and vibration isolation where the strut mount interface is critical.

What It Helps Address

• Suspension noise from worn or deteriorated isolator material.
• Vibration transfer from the road into the vehicle body.
• Excess movement at the strut-to-body interface.
• Steering feel issues related to suspension rotation and alignment of components.
• Premature wear on nearby suspension parts caused by poor isolation.

Installation Notes and Tips

Install ST-7906 in the front upper suspension location specified by the fitment data. Verify the vehicle application before installation and inspect the surrounding strut components, spring seat, and mounting surfaces for wear or damage. Proper seating and alignment are important for correct suspension operation.

Quality Assurance

Westar uses application-specific materials and a protective finish intended to support service life and maintain appearance. ST-7906 is built for the listed applications and is cross-referenced to common aftermarket part numbers for the same fitment.
