Product Details

The Stage 8 8916-S Locking Header Bolt Kit provides a reliable solution to prevent horsepower loss and gasket failure caused by loose fasteners. This 12-piece kit includes 3/8-16 x 3/4 inch double hex head bolts with a 6-point design, specifically engineered for header applications.

Patented Three-Piece Locking System:

  • High-strength 4130 alloy steel bolts for exceptional durability
  • Precision locking retainer mechanism prevents bolt loosening under extreme vibration and heat
  • Spring clip ensures constant tension and secure fastening
  • 3/16 inch recessed allen head for easy installation and removal

Kit Contents:

  • 12 locking header bolts with all necessary hardware
  • Application-specific sizing for proper fitment
  • Complete installation components included

Stage 8's trademarked locking fastener design has been trusted by performance enthusiasts and professional engine builders for years. The system is easy to use while providing superior holding power compared to traditional fasteners, making it ideal for high-performance applications where header bolts are subjected to repeated thermal cycling and vibration.
