From our northern friends in Canada come these excellent quality valve spring kits, utilizing ultra clean Kobe high silicon spring wire and precision-machined collars and steel keepers for improved valve control and long term durability. Development testing has shown AV&V’s retaining components to be over 50% stronger in destructive tests than stock. Dual spring kits have reduced top retainer diameters for minimal rocker box clearance machining.
