PAC Racing 300 Series Valve Spring Retainers

Expected motor life has increased greatly through the years, but anything with moving parts is susceptible to wear and will eventually need rebuilt. PAC Racing 300 Series valve spring retainers are made from 4140 aerospace grade chromoly steel, making them an excellent choice for stock to slightly modified rebuilds. PAC does their own in-house manufacturing, allowing them to build strength into these units. They are heat-treated for solid wear characteristics and to raise the tensile strength, and for a rust-free finish, they apply black oxide coatings. Into every engine a little work must go; make certain you use the right parts for your stock to slightly modified build with PAC Racing 300 Series valve spring retainers.
