### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Header bolt kit not as advertised
  

*by C***R on Reviewed in the United States on April 15, 2023*

This stage 8 part #8911A header bolt kit was advertised to have twelve 3/8-16 x 1" long bolts, twelve retainer washers, and twelve external snap rings. The kit that I received had thirteen bolts. One bolt was 1.25" long. Another bolt was 5/16-24 x 1" long. And a third issue was that one of the 3/8-16 x 1" bolts had severely damaged threads with heavy scrape type damage to the o.d. of the head and also had a white powder residue in the tread, on the hex head flats and in the retaining ring groove. I feel that I can state that this kit would not have been shipped from Stage 8 like this as I have used these products before with better quality.

    Perfect for Headers
  

*by R***E on Reviewed in the United States on November 24, 2021*

On any headers these work best if prior to installing the locking devices, you tighten them down every time you go out for a drive. I do it until they no longer tighten. That's the gasket your compressing. I did it about ten times/drives conducted on different days. Then the header wont leak.  The fasteners work as they say they do, they do not loosen!

    Works great
  

*by W***O on Reviewed in the United States on May 8, 2019*

These are the best bolts you can get for your headers and to all the people complaining about the lock washers not fitting its because you need to shave it down to fit in between some of your header tube all i did was take a drimmel and grind  the flat side down until it fit just as simple as that
