What It Helps Address

• Sagging or weakened spring support at the rear suspension
• Uneven ride height on the specified BMW applications
• Loss of proper suspension preload from a fatigued coil spring
• Noisy or unstable suspension behavior related to spring wear
• Restoration of factory-style spring geometry for the listed fitments

Installation Notes and Tips

Verify the vehicle position before ordering, since this spring is listed for rear use on the BMW 335i and front use on the BMW 330i. Compare the spring dimensions, code D4/D5, and the removed part against the vehicle’s original suspension component before installation. Because coil springs are under high tension, installation should be performed with proper spring-compression equipment and standard suspension service procedures.

Quality Assurance

Suplex suspension components are built for direct-fit replacement use in the applications listed above. Confirm fitment by year, model, and position before installation to ensure the correct BMW suspension spring is selected.
