Rough Country 770868_A M1 monotube rear shocks are built for lowered Ford F-150 4WD trucks that need controlled rear damping without guessing on shock length. Designed for 4 in. lowering applications and Rough Country lowering kits, this rear shock pair uses nitrogen-charged monotube construction with an internal floating piston to keep oil and gas separated, helping the suspension respond cleanly over pavement seams, rough streets, and uneven terrain.

Rough Country 770868_A Features:

• Rear mounting location with eye-style top and bottom mounts fits the lowered truck application specified in the catalog data.
• Monotube design uses a 46 mm digressive piston with self-adjusting deflective-disc rebound and compression control for quick response to changing road surfaces.
• Steel shock bodies are brushed, galvanized, and zinc-plated to help resist harsh weather and road debris exposure.
• Each shock uses an 18 mm centerless-ground, case-hardened, chromed, and super-polished rod for a smooth shaft surface and durable operation.
• Extended length is 23.82 in. and collapsed length is 15.35 in., with non-adjustable tuning for the listed lowering setup.
• Vulcanized natural rubber bushings help isolate vibration at the mounting points.
• Estimated installation time is 1 to 2 hours, based on the manufacturer information provided.

Includes:

• Pair of rear M1 monotube shock absorbers

Designed to work with Rough Country lowering kits on 4 in. lowered rear applications. The body-up mounting orientation is part of the intended installation layout for this M1 series rear shock pair.
