chro-Moly valve spring retainers / MACHINED keepers
Again, here are more parts Jim designed and had made for exclusively for us. These are much lighter and stronger-than-stock retainers are recommended with our 75lb. performance valve springs. Jim also designed the retainers to accept a dual valve spring set up too (see the kit below).
The keepers are also designed and custom made for us. These aren’t ordinary cast keepers, they are machined to fit and lock into the valve stem.
