Rough Country 502189 M1 adjustable lowering struts help give supported 1500 trucks a clean 2 in. front drop while adding monotube damping control for a tighter street stance. They are built for 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 models, plus the 2019 Chevrolet Silverado 1500 LD Classic, and are intended for use with Rough Country 2 in. lowering kit 71640.

Rough Country 502189 Features:

• Monotube construction uses a 2 in. seamless extruded tube body with a 46 mm digressive piston for responsive damping control.
• Self-adjusting deflective-disc valving manages rebound and compression independently, helping the suspension react to changing road surfaces.
• Notched body design allows ride-height adjustment through precise spring perch placement when paired with the required lowering kit.
• 18 mm centerless-ground, chromed, and polished rod supports smooth movement through repeated suspension travel.
• Zinc-plated corrosion-resistant finish helps protect the strut body from harsh weather, road salt, and road debris.
• Vulcanized natural rubber bushings are used to help reduce unwanted noise and vibration at the mounting points.
• Extended length is 18.50 in. and collapsed length is 14.92 in. for the documented M1 strut dimensions.
• Bolt-on installation is designed for basic tools, with an estimated installation time of 2 to 3 hours.

These lowering struts are designed exclusively to work with Rough Country 2 in. lowering kit 71640. They are not presented as a standalone lowering solution.
