Engineered to elevate driving dynamics, this rear shock absorber assembly set for the 20072017 Ford Expedition and Lincoln Navigator delivers controlled, composed suspension performance. Each unit features a thick-wall steel strut tube mated to a heavy-gauge coil spring, providing exceptional structural intensity and load-bearing confidence. The damper is charged with Japanese ENEOS damping oil, formulated to maintain stable viscosity and function across an extreme temperature range of -40C to 80C. Every batch of oil undergoes laboratory verification for density, viscosity, and thermal resilience, ensuring consistent damping from assembly to assembly. Rigorous validation includes over 600,000 fatigue cycles on the spring and 3 million endurance cycles on the damper, with damping force degradation held below 20% and no oil leakage. Installation dimensions are precisely controlled, with extension and compression lengths mirroring the original equipment to preserve full suspension stroke. Directly compatible with Sport Utility Vehicle models, this pair offers a disciplined, luxurious ride character without compromise.
