What Owners Say

Owners and enthusiasts frequently mention Ferrea valve springs alongside top-tier competitors like GSC and Kelford when discussing high-performance engine builds. The dual spring design earns specific praise for dispersing pressure effectively across both springs, which builders appreciate for reliability in demanding applications. These springs appear in recommended setups for aggressive camshaft profiles, particularly in Subaru and Mitsubishi builds pushing beyond 800 horsepower and 10,500+ rpm. While some enthusiasts express stronger brand loyalty to GSC beehive springs based on proven track records, Ferrea consistently makes the short list for serious engine builders who need springs capable of handling extreme valve lift and aggressive ramp rates without failure.
