The LESJOFORS 4008460 Front Coil Spring is engineered to enhance the suspension performance of BMW X5 3.0i models from 2001 to 2006. Designed to meet or exceed original equipment (OE) specifications, this coil spring ensures a precise fit and reliable operation, contributing to improved ride quality and vehicle stability. Constructed from high-strength steel, the spring undergoes heat treatment and shot peening processes to enhance its durability and resistance to fatigue. A zinc phosphate coating followed by an epoxy powder coat paint provides superior corrosion protection, extending the spring's lifespan and maintaining its structural integrity under various driving conditions. The LESJOFORS 4008460 Front Coil Spring is a direct replacement for the OE part number 31336750331, ensuring compatibility and ease of installation. By choosing this coil spring, fleet operators can expect consistent performance and reduced maintenance costs, as it effectively absorbs shocks and minimizes the impact of road irregularities on the vehicle's suspension system. This results in a smoother ride for drivers and passengers, as well as prolonged tire life due to even weight distribution. Additionally, the spring's design and material quality contribute to the overall safety and handling characteristics of the BMW X5 3.0i, making it a valuable component for maintaining optimal vehicle performance.
