The Pro Dual Valve Springs are a "must have" upgrade when running bigger lift cams and higher RPM's. With 100lbs of seat pressure 1.400" install height and open pressure of 225lbs (at .450" lift) they will work perfectly with any high boost application (20+ lbs of boost). These springs are rated up to 10,000 RPM and will accommodate cam lifts up to .515"!
LC Engineering Pro Dual Springs require our titanium retainers (part #1023243), hardened keepers (part #1023091) and spring seat (part #1023137). These parts are available as a complete kit (part #1023224). We also offer a lower pressure version of these springs for naturally aspirated or lower boost applications (part #1023216)
