What material are these coil springs made from?

These coil springs are made from high-quality chrome vanadium or chrome silicon steel. This material is chosen for its strong resistance to breaking, ensuring durability.

Will these springs maintain their height after installation?

Yes, Bilstein uses a hot setting process after forming the springs. This helps to effectively prevent any loss of height over time, ensuring the spring maintains its intended position.

Do these springs come individually or as a pair?

This product listing is for a single rear coil spring. If you are replacing springs, it is generally recommended to replace them in pairs on the same axle for balanced suspension performance.
