Forged one-piece construction to help with weight reduction & improved flow. Performance valves receive a swirl polish, smooth stem treatment, and are made of 21-2n/suh35ht stainless steel. Springs are made of swosc-v material (oil-tempered steel wire). Some springs feature a progressive style design with more coils on one end of the spring. Progressive springs are heavier on one end and should always be installed towards the bottom. Non-progressive springs are paint marked and should be installed towards the top.
