Product Description
Made by PAC Racing, these Lunati springs and retainers are among some of the best made. This package includes 32ea PN 74832 valve springs and 32ea, PN75799 steel retainers. We recommend these for most higher RPM/Power setups. They have .550 lift capability and a 90lb seat pressure. Because of their .550" lift capability they can be shimmed .030" if needed to get a hihgher seat pressure while still maintaining their lift capability.
