This valve kit includes 2 valves, 4 springs, 2 seats, and 2 retainers everything pictured in the listing. The components are designed to improve the performance and longevity of your valve train system:
Nitride-coated components enhance heat transfer and reduce carbon buildup, increasing valve train life.
Valves are forged from a single piece, which helps with weight reduction and improves flow.
Material: Valves are made from 21-2N/SUH35HT stainless steel.
Springs are crafted from SWOSC-V material (oil-tempered steel wire).
Some springs feature a progressive design, with more coils on one end. These should be installed with the heavier end towards the bottom.
Non-progressive springs are paint-marked and should be installed towards the top.
Seats are made from 4041 steel.
Retainers are constructed from 7075-T6 aluminum for added strength.
