Stage 8 Locking Bolts are easy to install and they 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 bolt (4130 Alloy Steel), a locking retainer and a spring clip or, depending on the application, a nut, a locking retainer and a spring clip.
