PAC Racing 1200 Series drag race valve springs are great for allowing you to get the most performance out of your engine. Select them when you're upgrading camshafts or doing engine rebuilds. The 1200 Series use a premium alloy that outperforms automotive industry standards; and PAC Racing processes the alloy to aerospace shot-peening standards to achieve superior fatigue dependability.
