Lunati Steel Valve Spring Retainers are made from 4140 chrome moly steel, which is stronger and harder than standard 1020 steel. This increased strength-to-weight ratio results in a durable yet light retainer. Retainers are available for 5/16",
3/8", and 11/32" valve stem diameters with 7 or 10 degree locks. All steel retainers from Lunati are black oxide coated for corrosion resistance.
