How Shocks Work

Designed to help keep your vehicle’s tires in contact with the road to maintain a high level of steering, stopping and stability, shocks are a key part of your suspension system. Shocks also help maintain a balanced ride by providing resistance to vehicle bounce, roll and sway as well as brake dive and acceleration squat.

Replacing a bad shock with a Monroe® Reflex® shock restores your vehicle’s original factory drivability and performance. Ideal for vehicles with a higher center of gravity, Reflex light truck shocks feature ASD valving technology that automatically adjusts the unit to absorb the impact, helping to reduce vehicle roll and dive. To learn how to install a Monroe Reflex rear shock, check out the steps for installing part number 911533 for 2007-2018 Chevrolet Silverado 1500 and GMC Sierra 1500.
