Engineered for the Toyota Tundra 4WD, this direct replacement front shock strut assembly with coil spring delivers refined damping and structural integrity. The damper is filled with Japanese ENEOS damping oil, formulated to maintain consistent performance across extreme temperatures from -40C to 80C. Each batch of oil undergoes rigorous laboratory testing for viscosity, density, and thermal stability to ensure uniform operation. The thicker strut pipe and heavier spring enhance overall strength, while the spring itself is validated through over 600,000 continuous fatigue cycles to confirm its high tensile resilience. The assemblys extension and compression lengths mirror the original equipment specifications, preserving the factory stroke and ride characteristics. A welded bracket endures 400,000 durability cycles under 0.8MPa tensile pressure, ensuring long-term structural reliability. After 3,000,000 fatigue durability tests, the damper exhibits no oil leakage and maintains a damping force decay rate below 20%. The assembled dimensions are 29.92 x 10.43 x 5.91 inches, and the unit weighs 42.11 pounds, reflecting its substantial construction for heavy-duty use.
