Product Details

Monroe Reflex Light Truck Shock Absorber 911151 is a suspension shock absorber engineered for front-end control on trucks that sit higher and carry more weight transfer during braking, cornering, and uneven-road driving. The Reflex Light Truck line focuses on responsive damping behavior, helping the shock react to impact changes rather than delivering a fixed response. For shoppers comparing Monroe 911151 against other options, this unit cross-references Monroe Shocks & Struts 540166 for the same application.

Compatible With 2007 Chevrolet Silverado 1500 Classic, front; 2007 GMC Sierra 1500 Classic, front; 1999-2006 Chevrolet Silverado 1500, front; and 1999-2006 GMC Sierra 1500, front. This fitment covers trucks without Electronic Adjustable Suspension, and the 2007 GMC Sierra 1500 Classic listing also excludes the Z71 Off Road Package.

What It Helps Address

• Excessive front-end dive during braking
• Body roll in turns and lane changes
• Harsh impact response over broken pavement
• Reduced control from worn front shocks
• Uneven ride quality on light truck suspension systems

Installation Notes

Install Monroe 911151 on the front position only for the listed Chevrolet Silverado 1500, Silverado 1500 Classic, Sierra 1500, and Sierra 1500 Classic applications. Fitment notes specify installation is recommended with the wheels on the ground. Verify the vehicle does not have Electronic Adjustable Suspension, and confirm the 2007 GMC Sierra 1500 Classic is not equipped with the Z71 Off Road Package. Check mount style and dimensions before installation.
