I had the installation done by the master of the job. But it was clear when I read the user manual. In the box of the product were all the products that were in the promotion.The materials are coated with black oxide, so it looks solid. Guaranteed products give me more confidence. The fact that the product is guaranteed for life indicates that the company trusts its goods.

There is nothing worse than doing a job twice which is one reason that we always use the most premium bolts or studs that we can find when doing engine work. This is even more true when working on these large expensive diesel engines. There are really only a couple brands out there that in our opinion exceed OEM GM, which are getting harder to find and super expensive. That said, we have used several sets for various engine made by this brand and honestly feel that they are one of the best out there. I actually write a note for the parts to on the diesels to see if this brand is available as first choice.The quality of materials use is top notch and the fit and finish is what one would expect in the aerospace industry. On a scale from one to ten on an overall quality scale they are an easy eleven. 100% happy with both the brand and the product.
