Product Details

KYB Strut-Plus SR4141 is part of KYB’s OE-restoring Strut-Plus product line, which is built around the idea that a strut assembly does more than absorb bumps. It supports vehicle weight, helps determine ride height, serves as a steering pivot, and contributes to stability and electronic safety system performance. For rear suspension service on the Ford Explorer and Mercury Mountaineer, this assembly is designed to replace worn components with a matched strut-and-spring package that follows OE specifications as closely as possible.

This part cross-references Monroe Shocks & Struts (e.g., 181125) for the same application. The KYB SR4141 is a direct-fit option for rear suspension repair on 2006-2010 Ford Explorer and 2006-2010 Mercury Mountaineer models, making it a practical choice when the original rear strut assembly has lost damping control or ride height.

What It Helps Fix

• Rear-end sag or uneven ride height
• Excessive bouncing after bumps
• Reduced handling stability in the rear suspension
• Noisy or worn strut assembly operation
• Ride quality changes caused by aging spring and damping components

Installation Notes

Fits 2006-2010 Ford Explorer, rear. Fits 2006-2010 Mercury Mountaineer, rear. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify rear suspension condition and confirm vehicle application before installation. Because this is a pre-assembled strut-and-spring unit, it is intended for a direct replacement workflow on the listed vehicles.

Quality Assurance

KYB is an original equipment supplier, and the Strut-Plus SR4141 is engineered to restore handling and control characteristics using OE-focused design principles. The assembly is built with KYB’s Excel-G strut technology and application-specific damping calibration to support consistent rear suspension performance on the listed Ford Explorer and Mercury Mountaineer applications.
