Engine Works 980-16 Valve Springs Dual 1.500 OD .800 ID
xtreem duty valve springs are made from Vanadium-Elector Ultra Clean material, this valve spring line represents 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 tolerances of +/-10% of the stated spring rate. Our choice of Chromium Silicon III and xtreem Alloy gives engine builders reliable dampening and precision valve control lap after lap or pass after pass. These xtreem alloy springs are simply the best. Each sprig is precision wound, ground for tolerance, and stress relieved to ensure longevity in extreme engine conditions.
MADE IN USA!
