Designed for high rpm, BC valve springs by PAC Racing are wound from only the highest grade, super clean, chrome silicone alloy and feature proprietary processing procedures for consistent pressures. BC titanium retainers are CNC machined from 6AL4V round bar titanium to exacting tolerances.
These valve springs and retainers work with all SRT4/PT lifters, and rockers, as well as larger SRT4 valves.
The kits are offered for use with triple groove valve keepers (stock) or single groove valve keepers for use with aftermarket larger valves. You can also buy the springs and retainers separately.
