      Description

      Ultimate Exhaust Header Security. Regular exhaust header bolts are okay for regular engine applications but when you’re running some serious power through your Mustang GT’s Coyote 5.0 V8 engine and the pressure is really on, you simply can’t afford to have an exhaust header bolt back out. Eliminate leakage and the risk of blowing an exhaust header gasket by fitting a set of these premium Stage 8 Locking Header Bolts from Kooks. Everything you need is included and your engine’s performance will really thank you.

      Grade-8 4130 Alloy Steel Steel. Stage 8 Locking Exhaust Header Bolts are made from grade-8 aircraft-quality 4130 alloy steel and feature a duplex nickel finish. The patented three-piece system has a grooved bolt with a retainer piece and a spring clip. Once the bolt is securely installed, the retained goes over the head of the bolt and fits up against the exhaust header, with the clip snapping into the groove to provide a secure fit that can’t jiggle loose. From materials to design and engineering, your exhaust headers will enjoy a security of installation that can’t be beat.

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

      Application. The Stage 8 Locking Header Bolts fit the Coyote 5.0 V8 engines in Mustang GT, Dark Horse models from 2015 to 2025.
