Description
Header bolts take a beating from thermal cycles and vibration, and standard fasteners will work loose over time—potentially causing exhaust leaks or catastrophic gasket failure. Proform’s wedge locking design eliminates fastener creep without the brittleness of nylon-insert lock nuts, making these bolts the go-to choice for serious engine builders and track racers. Get 16 bolts per set, enough for a complete header installation with spares.
