Product Details

Monroe Reflex Light Truck Shock Absorber 911131 is a front suspension shock absorber for vehicles that need controlled ride response without sacrificing everyday drivability. The Reflex Light Truck line focuses on higher-riding vehicles, and this unit uses automatic damping adjustment to help reduce roll and dive when the chassis loads and unloads. It is a direct-fit suspension shock absorber for select Ford F-250, Ford F-150, Ford F-150 Heritage, Ford Expedition, and Ford F-100 Ranger front applications.

This part cross-references KYB 565004 and Rancho RS55235 for the same application.

What It Helps Address

• Excessive front-end dive during braking
• Body roll in taller trucks and SUVs
• Harsh response over bumps and road joints
• Unstable ride feel on worn front shocks
• Reduced control in front suspension movement

Installation Notes

Verify the vehicle’s front mounting style before installation: upper stem mount with 2.5/8" stem length and 1/2"-13 thread pitch, and lower cross pin mount with closed-ended 5/16" hole ID. Confirm compressed length, extended length, and travel length against the original shock to ensure proper suspension travel and clearance. This Monroe 911131 shock absorber is listed for front use on 1997-2009 Ford F-250 models with 8,500 lb GVW and under, 1997-2003 Ford F-150, 2004 Ford F-150 Heritage, 1997-2002 Ford Expedition without Automatic Rear Air Leveling System, and 1997-2001 Ford F-100 Ranger.
