Front Suspension Kit includes strut assemblies, coil springs, and front lower control arms designed for use with specific vehicle models.Each component is engineered to meet OE specifications and ISO quality standards, compatibility with the design.The kit is factory tested for performance, and function to support proper suspension.The strut assembly incorporates damping oil that maintains consistent performance in extreme temperatures ranging from -40°C to 80°C.This damping oil has been laboratory tested for viscosity, density, and low-temperature functionality to batch-to-batch consistency.The strut tube is constructed with increased wall thickness, and the spring is built to provide enhanced strength and.Springs undergo over 600, 000 cycles of fatigue testing to verify tensile strength and long-term.Installation dimensions are precisely controlled to fitment compatibility.The spring's extension and compression lengths match the specifications, maintaining the same stroke length as the factory unit.Shock absorbers are subjected to 3 million cycles of fatigue endurance testing with no oil leakage, and the damping force attenuation remains within 20%.Mounting brackets are tested under 0.8MPa of tensile pressure for 400, 000 cycles to validate structural integrity.The cover withstands 300, 000 test cycles without failure.The rigid mount structure helps minimize vibrations generated during shock absorber movement, contributing to reduced noise and improved ride comfort.All components are manufactured under strict material controls with seven in-process quality checkpoints to maintain consistent production standards.Packaging materials are selected to support environmental sustainability goals.This kit is intended for vehicles equipped with a 3.5L V6 engine and 6-speed automatic transmission.Application is specifically matched to the designated model years and configurations.Package includes 1x Front Left Strut with Coil Spring Assembly 1x Front Right Strut with Coil Spring Assembly 1x Front Lower Control Arm – Passenger Side 1x Front Lower Control Arm – Driver Side Interchange numbers: 2335909L, 272971, 51621T2F329, 51621T3L317, 92141230, 51611T3L316, 272970, 2335909R, 51611T2F329, 92141229
