HEAVY DUTY VALVE SPRINGS

Made from Vanadium-Elector Ultra Clean material, these valve
springs represent some of the best springs on the market when
used under race conditions because of their long life expectancy.
Each set is batch tested for consistency and matched to +/- 10%
of the stated spring rate. Each spring is precision wound, ground
for tolerance, and stress relieved to ensure longevity in extreme
engine conditions.
