Stage 8 Header Locking Nut Kit

Stage 8 Locking Header Nuts are easy to use and are real assurance against horsepower loss or gasket failure created by loose nuts or bolts. The unique patented and trademarked functional design is just three pieces: a nut (4130 Alloy Steel), a locking retainer and a spring clip. All Stage 8 Locking Header Nut Kits are sold with all of the necessary hardware for your application.

Kit contains 10 10mm-1.25 nuts.

Do NOT use these on turbo mounting fasteners! Locking hardware on these kits is aluminum and will not withstand the head generated by a turbocharger. Turbo mounting hardware includes SS hardware.
