Product Description
- Lunati valve spring kits were designed to get the most power out of Harley upgrades and are a perfect match for a Lunati Harley cam.
- Each kit contains (4) each of the following items: valve springs, retainers, locks and locators.
- Valve locks are manufactured from fatigue-proof steel and then heat treated for hardness and to reduce wear and distortion, while our locators are engineered from a high-strength steel alloy that holds the spring in place and requires no machining.
- Steel retainers are constructed from 4140 chrome moly steel, which is stronger and harder than standard 1020 steel. This increased strength to weight ratio results in a stronger yet lighter retainer. All steel retainers from Lunati are black oxide coated
