Product Details

The Monroe Reflex Light Truck Shock Absorber line is aimed at trucks that carry a taller stance and need more controlled suspension response. On 2011-2019 Chevrolet Silverado 2500 HD and Silverado 3500 HD, as well as 2011-2019 GMC Sierra 2500 HD and Sierra 3500 HD front applications, this shock absorber uses Monroe’s Reflex design to react to changing road input and help reduce excessive pitch and roll.
