About the Adjustable Suspension Kit | Ride Height Adjust | Can-Am Defender…

Improved Stance, Balance, and Confident Control: Take your Can-Am Defender to the next level with Rough Country's M1 Adjustable Coilovers. Designed to dramatically improve ride quality, these high-performance shocks stabilize suspension movement for better control during cornering, braking, acceleration, and uneven terrain. The adjustable ride height design allows fine tuning from 0 to 2 inches of lift, helping prevent suspension overextension while delivering a smoother, more predictable ride. Featuring a 46mm digressive piston and advanced monotube construction, M1 Coilovers instantly react to changing surface conditions, maintaining comfort on the trail and stability under load.

Engineered Strength and Precision Performance: Built for demanding workdays and weekend trail rides, Rough Country's M1 Coilovers are constructed from a heavy-duty 2-inch seamless extruded shock body for increased durability and heat dissipation. The threaded, grooved shock body allows easy ride height adjustments even after installation, while the self-adjusting deflective-disc valving independently manages rebound and compression for consistent, fade-free performance. An 18mm case-hardened, chromed, and super-polished shock shaft delivers smooth operation and extended seal life, while silent block rubber bushings reduce vibration and unwanted noise. Finished in a corrosion-resistant zinc plating, these coilovers are built to withstand harsh environments and long-term use.

Simple Installation and Proven Warranty Coverage: This bolt-on coilover kit installs using basic tools with an estimated install time of 2 to 3 hours. A spanner wrench is included to make ride height adjustments fast and precise. Whether you are adding ground clearance for off-road use or restoring factory ride height with improved control, Rough Country's M1 Coilovers deliver dependable performance. Backed by a 3-year manufacturer replacement warranty against defects in materials and workmanship, you can upgrade with confidence and peace of mind.
