Bilstein 04-07 BMW 525i B3 OE Replacement Coil Spring - Front

If you're working on the front suspension of your 2004-2007 BMW 525i, this Bilstein B3 OE Replacement coil spring is designed to bring your vehicle back to its original factory ride height and handling. It's built to match the original dimensions, spring rates, and design types, ensuring your suspension functions as intended by the manufacturer.

Bilstein makes these springs using high-quality chrome vanadium or chrome silicon steel, which is known for its resistance to breaking. They use a hot setting process after forming the spring, which helps prevent any loss of height over time. This means you're getting a well-built part that will maintain its position and support your vehicle's weight reliably.

When you install these springs, you're essentially restoring your BMW's suspension system to its original factory specifications for both function and safety. This is a direct replacement part, meaning it's made to fit right in place of your old, worn-out springs.
