Stage 8 Locking Header Bolts easy to use but they are absolute insurance 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. The bolts are application specific.
Regular header bolts can come loose and cause gasket failure.
The Stage 8 locking header bolts have a special dual locking washer design that will not allow the bolts to back out.
Fits 170,200 engines.
