Stage 8 locking bolts are your best insurance against mechanical failures. They hold bolts tight, and in place. The popular locking header bolts are the best way to keep your headers free from exhaust leaks and blown header gaskets. These bolts will NEVER loosen until you remove them. Visually inspectable, reusable, and your best bet against noises, leaks, and power loss.
For more info on how these work, please visit this page for pictures and descriptions.
You get a complete set of twelve (12) bolts – enough for one car. The bolts are M8 x 1.25mm x 22mm in size and have 6-pt double hex heads with patented groovelock technology.

Have 02 T/A Ram Air WS.6 Convertible. Installed KOOKS stepped 1 3/4 to 1 7/8 headers to my exsisting Borla exhaust. Very impressed and happy with set up-the Stage 8 Locking Header Bolts when used in conjuction with the stock GM metal header gasket is a good guarantee you will not have any header leaks right after or meny months/years after install.
I would highly recomend spending the little extra money!

Have 00 T/A Ram Air WS.6. Installed KOOKS stepped 1 3/4 to 1 7/8 headers to a LM2. Used the Stage 8 Locking Header Bolts with the stock GM MLS header gasket and not a single leak yet.
I’d definitely recommend spending the extra money on these bolts!!!
