- Clay Smith recommends the use of Spring cups on all cylinder heads. They not only protect the head and shim, but also locate and align the spring.
- Maintaining correct spring, retainer seat and valve alignment ensures long valve spring longevity and minimal valve stem and guide wear.
- Clay Smith spring cups are precision machined and heat treated for maximum strength.
