Product Details

The Stage 8 8933 Locking Header Bolt Kit provides secure fastening for header installations with a patented three-piece locking system that prevents loosening from vibration and heat cycling. This 16-piece kit includes 3/8-16 x 1 inch bolts with 12-point heads, engineered specifically for exhaust header applications.

Key Features:

  • Patented three-piece locking system: 4130 alloy steel bolt, locking retainer, and spring clip
  • 12-point head design for improved grip and accessibility in tight spaces
  • 3/8-16 thread x 1 inch length bolts
  • 16-piece complete kit with all necessary hardware
  • Prevents horsepower loss and gasket failure caused by loose fasteners
  • Heat-resistant design for high-temperature exhaust applications

Stage 8's unique locking fastener design eliminates the need for lock washers or thread-locking compounds. The spring clip retainer maintains constant tension on the bolt, ensuring it stays tight through extreme temperature changes and vibration. Each kit is application-specific and includes everything needed for a complete header installation.

Easy and fast

I thought my order was going to take longer to ship and it surprised me after I called Autoplicity I thought another few days before it shipped and it arrived. The lowest price I found on my Mishimoto radiator was on Autoplicity.

orders come really fast like next day...

good price, fast ship, will recommend.

Quality air cleaners. They also come with a custom wing nut. Edelbrock comes with a cheap cast wing nut.

Easy experience with this website, I would definitely recommend!

Could not have been easier. Product was correct, fit well, functioned perfectly and arrived on time. Thank you!

It was easy and delivery didn't take long.

This is my second time ordering from Autoplicity and both times they had the lowest price on the items I was looking for (brake pads and CAI filter). Fast shipping, my filter was at my door two days later. Overall very satified.

Great products, and pricing

I was amazed to find the air intake I wanted at the price offered by Autoplicity. No one else came close and the item was shipped very quickly. This store has been added to my favorites list........Thank You!!!!

I ordered a universal Hurst Pistol Grip "shift knob" for my '12 Mustang GT. It squeezed to a perfect fit right where I need to grip it. It improved shift time and accuracy greatly and feels and looks great! Autoplicity had the best price on the web and I got this in 3 business days. I recommend this product.

Order was fast, had the products I wanted in stock, and vehry pleased. Thank you 5 star service.

I received my Corsa exhaust for my Sequoia today; I had issues with Autoplicity with regard to the order/availability which once brought to their attention was rectified; in the end I had to wait a little longer than expected to receive my order but it was resolved and hopefully the management learned something from this experience.
