2 Stars   so close to perfect

I got these locking fasteners after having repeated issues with my header bolts loosening.

The hex in the head is useful for about three bolts out of the 16, but that's BBK and Ford's problem.

The reason I'm disappointed with the kit is simple. There are two sizes of the locking cam, one fits between the bolt and tube, and the other does not. The one that fits? they gave me 8 of them. The one that doesn't? I have 16 of those. So, here I am modifying 8 of the larger ones to fit.

On top of that, the C-Clips that hold the lobe-shaped retainer on can be bent if installed improperly. I've installed one wrong, and dropped one to who knows where. The issue with this? I was only given 16 C-Clips, which means I'm headed to Fastenal on my work break to see if they have any.

If this kit was $30, I would forgive this all.

For $65, you can send me a few extra pieces of steel and a few extra C-Clips.

I'm Disappointed.

Aside from these issues, the locking mechanism seems like it will stay for years without needing to be retightened, which is the only reason it gets as high of marks as it did.

Despite all of that, If a friend were doing this job, I'd have them do it with these the first time to save the headache of taking the car apart as many times as I have.

Yes, I would recommend this item to a friend!

I bought these expecting them to work as the picture showed, but the don't.The tear drop piece was not long enough to reach the header tubes and I wound up bending them around the side of the header flange. I dont know how well they will work like that but I shall soon find out. Although not like the picture, I do believe they will still work.Its a simple design that could be used in a multitude of ways. And knowing what I know now, I would purchase this product again. Thanks Stage 8.

Yes, I would recommend this item to a friend!

I bought these to go with some headers that I'm about to buy. So I haven't installed them yet but I bought a set a couple years ago and they worked great! We all know it's really tight inside the DOHC 4.6 engine bay, that's why I loved how these have a 6 point bolt head and also accepts an Allen wrench!

Yes, I would recommend this item to a friend!
