What I like about the Stage 8 8900 Locking Header Bolt Kit, I like how I installed the kit and have had no exhaust leaks since. Very easy to install and most importantly, no leaks. Prior to installing this Header Bolt Kit, I would have to retighten the bolts at least weekly and still have an exhaust leak somewhere. Now, no leaks and I have not touched or looked at the bolts for over a month. I installed the Locking Header Bolt Kit on a 1999 GMC 6.0 with Long Tube Headers.

If you put headers on an engine you need these bolts. Trust only stage8 header bolts

Wrote a one star review at first because I thought I only received 10 bolts but the other two fell under my recliner

Forget anything else. These bolts will stay in place, and come out with no effort when required, as no Loctite is required.

Very nice quality stuff here. I have tried so many fasteners on my headers and turbo manifolds and finally found the ones I'll use from now on. The concept is so simple and yet works so well. I dont have the patience to deal with the one you wire together with steel wire and slick up your hands. Highly recommended that you invest in these, you wont be sorry. A little extra coin but its well well worth it.

Make sure you have someone around with smaller hands, as the retaining clips are hard to install, but with some patience, they will go on. I would purchase again.
