This direct replacement front strut and coil spring assembly fits 2014, 2015, 2016, 2017, 2018, and 2019 Toyota Corolla models, restoring factory ride quality and handling. Each assembly integrates a heavy-gauge spring and a thicker strut pipe to enhance structural intensity. The damper is filled with precisely formulated Japanese ENEOS damping oil, validated for viscosity, density, and stable function between -40C and 80C. This ensures consistent shock absorption across extreme temperatures. Stringent quality control includes over 600,000 fatigue tests on the spring for high tensile strength and 3 million endurance cycles on the damper, with damping force attenuation remaining under 20% and no oil leakage. Installation dimensions are strictly controlled so extension and compression lengths match the original equipment, preserving stock stroke and compatibility.
