Kooks Stage 8 Locking Header Bolts (11-14 Mustang GT)Find parts that fit my vehicle

Outstanding Exhaust Header Security. Ordinary exhaust header bolts might be okay for ordinary engine applications but if you’re running serious power from the Coyote 5.0 V8 engine in your Mustang GT and are under big pressure, you just can’t afford for an exhaust header bolt to back out. Avoid the risk of leakage or a blown exhaust header gasket by installing a set of premium Stage 8 Locking Header Bolts from Kooks. The kit includes everything you need and your Mustang will definitely thank you with the boost in reliable performance.

4130 Alloy Grade-8 Steel. These Stage 8 Locking Exhaust Header Bolts are constructed out of aircraft-quality grade-8 4130 alloy steel and finished with duplex nickel plating. The Stage 8 patented 3-piece system uses a grooved bolt, a retainer piece and a spring clip. When the bolt is securely in place, the retainer fits over the bolt head and secures up against the exhaust header, the clip snapping firmly in the groove to make a secure fit that won’t jiggle loose. From materials to design and engineering, your Mustang’s exhaust headers enjoy a security of fastening that cannot be beat.

Lifetime Manufacturer’s Warranty. Stage 8 Locking Header Bolts are covered by a lifetime manufacturer’s warranty.
