This front strut assembly with coil spring is engineered for direct replacement on 2011, 2012, and 2013 Kia Sorento models. It integrates a thicker strut pipe and a heavier spring to deliver enhanced structural strength and consistent suspension performance. The spring has undergone over 600,000 continuous fatigue cycles to confirm its high tensile durability. Inside the damper, Japanese ENEOS damping oil maintains stable operation across a wide temperature range from -40C to 80C, verified by rigorous lab testing for viscosity, density, and thermal stability. The damper itself has passed 3,000,000 fatigue durability tests without oil leakage, and damping force decay remains under 20%. A welded bracket has withstood 400,000 durability cycles under 0.8 MPa tensile pressure, ensuring mounting integrity. Dust protection and proper stroke alignment are maintained through a tested dust cover and extension-compression lengths that match original factory specifications. With a package weight of 20 kg and assembled size of approximately 29.1 x 12 x 7.9 inches, this unit arrives ready for professional installation on the front axle of compatible Sorento sport utility vehicles.
