The QualFast 2015 catalog, including performance valves and valve train components, is now available in print. The 2015 performance catalog introduces a brand new racing valve series called Black Lightning.
Black Lightning valves feature nitrided stems, combined with swirl-polished underheads, undercut valve stems, and thinner margins for the most demanding pro race engine environments.
The new catalog also adds over forty new street valve performance applications to the very popular street valve series. Three new diesel performance springs, and various new retainer and guide plate applications enhance the offerings of the QualFast performance line.
