Stage 8 Locking Header Fastener Kits

Upgrade your exhaust hardware with Stage 8 Grade 8 Locking Header Fasteners. These patented fasteners include a grooved hex-head bolt or nut, a retainer, and a snap clip. The retainer fits over the bolt head and locks it against the header tube, while the snap clip holds the retainer securely in place.

Once installed and tightened, these fasteners won't back out, eliminating blown gaskets and exhaust leaks caused by loose bolts. Perfect for performance engines, headers, and exhaust manifold upgrades.
