SET OF SIXTEEN
Ferrea designed and developed as a solution for the Top Fuel & Funny Car engine builders experiencing problems of premature wear in the lock and tip area of the valve. So when premature failure started happening in the sport compact ranks, Ferrea was ready with plenty of solutions. Ferrea's new lock assembly replaces the need for hard tips, by incorporating a special lash cap which is surrounded by a shouldered valve lock which "locks" the valve stem above and below the keeper groove and secure the lash cap to prevent any unwanted movement. The innovative new lock design is the choice of many Drag Racing and Winston Cup engine builders.
