The S54’s valve train just became bulletproof. If you are tracking your M3 or you’re running some aggressive cams, safe to say you know the risks that come with that. Our engineers put the effort in to solve one of the platforms weakest links! Forged from chromoly steel, DLC coating for reduced friction, and tested to be compatible with aftermarket cams! Listen, this is isn’t just an upgrade but rather its insurance against catastrophic failure. You know the saying, do the job once & do it right. Give us a call & let’s bulletproof your S54 cars!
