Product Details

The Stage 8 8906M Locking Header Bolt Kit provides reliable security against loose fasteners that can cause horsepower loss and exhaust gasket failure. This application-specific kit includes 16 pieces of 8mm-1.25 x 25mm metric bolts with 6-point double hex heads and recessed allen drives.

Key Features:

  • Patented three-piece locking design with bolt, retainer, and spring clip
  • Manufactured from high-strength 4130 alloy steel for durability
  • 6-point double hex head with 3/16" recessed allen drive for easy installation
  • Metric thread specification: 8mm-1.25 x 25mm length
  • Complete kit includes all necessary hardware for installation
  • Prevents fastener loosening from vibration and heat cycling

Stage 8's unique locking system ensures your header bolts stay tight under extreme operating conditions, maintaining proper exhaust sealing and preventing performance-robbing leaks. The simple three-piece design installs easily while providing superior locking capability compared to traditional lock washers or thread lockers.

It was quick and easy to place the order for my 1996 Pontiac Firebird. I would recommend & use your online ordering system again.

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 !

Autoplicity was quick and easy. Painless web format. Shiped right away. And reasonably priced too.

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.

Easy order placement, fast shipment
