Product Details

The Stage 8 8913B Locking Header Bolt Kit provides a reliable solution to prevent header bolt loosening caused by extreme heat and vibration. This 16-piece kit includes 3/8-16 x 1-1/4 inch bolts with 12-point heads, designed specifically for secure header installation.

Key Features:

  • Patented three-piece locking design prevents loosening from heat and vibration
  • 4130 alloy steel bolts for superior strength and durability
  • 12-point head design for easier access in tight spaces
  • Includes locking retainers and spring clips for each bolt
  • 16-piece kit provides complete hardware for most applications
  • Prevents horsepower loss and gasket failure from loose fasteners

Stage 8's unique locking system uses a functional three-piece design: a high-strength 4130 alloy steel bolt, a locking retainer, and a spring clip that work together to maintain constant clamping force. This proven design ensures your headers stay securely fastened even under the most demanding racing and performance conditions.

super fast shipping!!!

Paid for 2 day shipping And took a week

Easy, fast, loved it

Very easy to use and the price is right!

Quick and easy!

No problem, good price. Would like to have an estimated delivery time.

Great

I paid for 2nd day shipping and 5 days later they were shipped out. So, I should receive my rotors in a full week from when I paid for 2 day shipping. I called customer service and they discounted the shipping rate to ground service. At least they were polite and helpful in the phone.

great experience, good price, item arrived within 4 days of purchase, would do business with again in future !

glad to find this web

Customer Service was excellent. Their online website provided accurate product description and when I called to double check, the gentlemen handled my request with ease and professionalism. Thank you for providing the best pricing on great automotive products. My wife and I purchased a WeatherTech trunk liner that would have cost me over $100 retail price but was able to purchase from Autoplicity for much less!!! Thanks guys and keep up the good work!!

By far the lowest price i've seen on the web for what i have been trying to get, the Injen SRI for my juke. Great price fast shipping! Ill buy all my car stuff here from now on.
