VH45DE Valvetrain Kit

The PerformanceVH VH45DE valvetrain heavy duty spring and titanium retainer kit is a must for your high performance engine build. The heavy duty springs raise the seat pressure to 95lbs., and has 190lbs. at 10mm lift. The OEM spring only has a seat pressure of 49lbs. Worn OEM springs will have even less! The higher spring pressure allows you to acquire higher revs with out the worry of valve float. This is a highly recommended upgrade for turbocharged vehicles and applications involving upgraded camshafts.
