Product Details

Monroe Reflex Strut 71139 is engineered for rear suspension replacement on 2007-2024 Ford Expedition and 2007-2021 Lincoln Navigator models listed below. The Reflex product line focuses on controlled damping response, using ASD valving to react to impact and help maintain stable ride characteristics across varying road surfaces. This rear strut is a gas charged unit, so the strut rod extends automatically during service and installation.

This part cross-references KYB 340072 for the same application. Monroe 71139 is also referenced by part number 71139 in catalog listings for the same rear suspension position.

What It Helps Address

  • Rear-end bounce or reduced damping control
  • Excessive movement over rough or uneven pavement
  • Worn rear strut performance on Expedition and Navigator models
  • Ride instability caused by aging suspension components
  • Loss of consistent control in changing road conditions

Installation Notes

  • Fits 2018-2024 Ford Expedition, rear
  • Fits 2018-2021 Lincoln Navigator, rear
  • Fits 2014-2017 Ford Expedition, rear; for vehicles without electronic adjustable suspension
  • Fits 2014-2017 Lincoln Navigator, rear; without Automatic Leveling System and without Electronic Adjustable Suspension
  • Fits 2007-2013 Ford Expedition, rear
  • Fits 2007-2013 Lincoln Navigator, rear; without Automatic Leveling System

Verify rear suspension configuration before ordering, especially on 2014-2017 Ford Expedition and Lincoln Navigator models with electronic adjustable suspension or automatic leveling systems. Compare compressed length, extended length, and body dimensions to the original strut during replacement.
