        Works Great

        This is my second set. My first set I put on my F150 and have had them on for 2yrs with out any issues. Now I installed my second set on my mustang. Easy to put on and work great.

        ...

        For what they are, the job is a bit of a pain. Either way, I needed them, and ultimately they really are worth it.

        1 1990 GT - Duckie

        The Ford Racing Header Bolts did not work for me.

        Don't know that it was the header bolts' fault. The bolt holes on the Ford Racing Shorty Headers were so close to 3 ports (2 on the passenger side and one on driver side) that I could not get the threads started on a total of 5 bolts. 2 other mechanics tried to get these bolts started without any luck either. There was no consideration for the oil dip stick brace either. So, I used the header bolts that came with the FR headers and the OEM header bolt that kept the dip stick brace. A.M. was great on delivery, only 2 days after order with standard shipping. Just wish these bolts would have worked.

        stage 8 bolts

        Awesome header bolts! Super strong and will not back out. With the locking technology on these bolts it is virtually impossible for them to come loose. So that means no header leaks! Great product! Thanks.

        Awsome locks!!!

        I won't find another empty hole where a bolt use to be. I had 2 factory bolts back out completely on my stang, after some time passed. I had a leak which became annoying. I installed these locking bolts. The leak is gone and I don't have to worry about it anymore. I highly recommend this product.
