About this part

Lower Your Ride. Raise Your Standards: Unlock the full potential of your lowered suspension with Rough Country's M1 Loaded Struts, engineered specifically for use with Rough Country's lowering kits. These performance struts are designed to deliver a lower ride height without sacrificing ride quality, giving your vehicle a sleek stance and sharper handling dynamics. From tight turns to daily driving, the M1's monotube design and digressive valving react instantly to surface changes for a stable, composed ride. Street-Tuned for Precision and Control: Built around a robust 2-inch seamless extruded body and a 46mm digressive piston, the M1 struts provide consistent, fade-free damping performance. Self-adjusting deflective-disc valving ensures that rebound and compression stay balanced, even on unpredictable surfaces. The ride height is fully adjustable using the notched body design, allowing precise perch placement for dialing in the perfect drop. An 18mm chromed and polished rod and vulcanized natural rubber bushings add long-term durability and vibration control. Clean Looks. Confident Ride. Bolt-On Install: Zinc-plated for corrosion resistance and built to last, these struts are as tough as they are sleek. Installation is 100% bolt-on and can be done with basic tools in about 2-3 hours. Backed by Rough Country's 3-Year Manufacturer's Warranty, the M1 Loaded Struts are the ideal solution for leveling out your lowered stance and upgrading your ride quality in one go.
