Rough Country's M1R Adjustable Reservoir Loaded Struts bring monotube performance and external reservoir cooling to the 2021-2026 Bronco front suspension. Available in multiple lift heights to match your build, these struts replace the factory units entirely and arrive pre-assembled, cutting install time down to a manageable 2-3 hours with basic hand tools.
External reservoir monotube construction. A 46mm monotube body paired with a remote reservoir keeps oil and nitrogen separated by an internal floating piston. That separation dissipates heat faster than twin-tube designs and eliminates fade during extended off-road use, so the damping stays consistent from the first trail run to the last.
Digressive valving that reacts to the terrain. The 2-inch digressive piston uses self-adjusting, deflective-disc independent rebound and compression tuning. On smooth pavement the valving stays compliant; when the surface gets rough, it stiffens up instantly. The result is a strut that handles both the highway commute and a rocky two-track without requiring a manual adjustment between them.
Adjustable ride height built into the strut body. Multiple grooves machined into the 2-inch seamless extruded tube let the spring perch be raised or lowered to dial in exact ride height after installation. The 16mm centerless-ground, case-hardened, chromed, and super-polished rod resists corrosion and flex under load, while durable vulcanized natural rubber bushings absorb NVH without adding harshness.
