Detailed Description

The Monroe 911550 is a telescopic suspension shock absorber engineered for rear fitment on 2018-2025 Jeep Wrangler models. Its progressive valving and gas-charged construction help maintain ride control while filtering harsh impacts, making it a practical choice for drivers looking to restore original handling feel. This part number, 911550, is part of Monroe’s OESpectrum Monotube Shock Absorber line and is cross-referenced with KYB 5550017 for the same application.

Fitment language for this application is direct: Fits 2018-2025 Jeep Wrangler, rear. The shock uses a steel body, black painted finish, and loop-style mounting points with center-of-loop measuring references for accurate replacement selection. Part number 911550 is also listed under Monroe Shocks & Struts 911550.

What It Helps Solve

  • Excessive bounce or reduced damping control.
  • Harsh impact feel over uneven pavement or trail surfaces.

  • Loss of factory ride quality in rear suspension service.
  • Fitment issues when replacing a worn rear shock on the listed Jeep Wrangler applications.
