Eibach springs are cold-formed on CNC machinery to ensure precise tolerances for spring rates and free height, contributing to a longer lifespan. The manufacturing process includes heat tempering, shot peening, pre-setting, and a final tempering for maximum stress resistance. For durability and aesthetics, the springs are phosphate treated and finished with a black powder coat for corrosion protection and resistance to chipping. Each spring is imprinted with an Eibach logo and part number, and guaranteed to remain within 3% of its original rate and height for its life.
