Product Details

The Stage 8 6905 Locking Header Fastener Kit is engineered specifically for Cadillac 3.6L V6 applications, providing a permanent solution to the common problem of header bolts loosening due to heat cycling, vibration, and exhaust pressure. Stage 8's patented locking fastener system mechanically locks each bolt in place, eliminating the need for thread lockers or constant re-torquing.

Key Features:

  • Patented locking fastener system prevents bolts from backing out
  • Designed specifically for Cadillac 3.6L V6 header installations
  • Withstands extreme heat and vibration associated with exhaust applications
  • No thread locking compounds required — mechanical lock holds securely
  • High-strength hardware constructed to meet or exceed OEM specifications
  • Complete kit includes all necessary bolts, locks, and retaining clips for a full header installation
  • Reusable and re-torqueable without replacing the locking components

Stage 8 locking fasteners are a trusted choice among performance enthusiasts and professional installers who demand reliability in high-heat exhaust environments. The Stage 8 6905 kit delivers peace of mind knowing header bolts stay tight mile after mile.

The order was shipped promptly, and everyone was is good working condition. I will order from here again!!

Great price and super fast shipping.

Fantastic price, positive communication, arrived before promised worked out great!

This is our second order from Autoplicity. The first one didn't go so well due to a mix up with the Sparco seat pricing. Though I was starting to question our decision to order from them after several emails and phone calls and online chats, they came through in the end. These guys earned our second order by honoring the price they had listed and then calling to follow up when our race seat was shipped. Since this group was able turn our bad experience into a positive one we made our second order and, so far, it looks like they are again getting us what we want at the best price we can find. We are happy to recommend Autoplicty and plan on using them for future orders. There is one specific thing we would recommend, change the quality and volume of the hold music on the 800 #. It sounded like we were calling a 1970's van with a blown Jensen stereo turned all the way up,...

Pleasure to deal with, will use for future purchases as well.

I placed an order on Sunday and received my order on Wednesday morning. Product was carefully packaged and as advertised. Will buy from Autoplicity again. Thanks for the great service. Order number #18578

Very good price on k&n air filter, will definitely order from autoplicity again.

I ordered some floor mats for a Prius. Autoplicity was very competitive in their pricing. Not only that, they shipped quickly and had great feedback during and after I ordered. I would purchase from them again!
