Description
Header bolts experience constant thermal cycling and vibration that can loosen standard fasteners, potentially causing exhaust leaks and loss of performance. Proform’s wedge locking design prevents bolt creep without compromising installation ease, giving you a secure, leak-free header assembly that stays tight through countless heat cycles. This is the fastener solution serious builders and racers rely on.
