Extended Length for Custom Exhaust Systems

When you need a longer reach for your exhaust collector connections, the Stage 8 Collector Bolt Kit (8950S) is the ideal choice. With a 3/8-16 thread and a 1.5-inch length, these bolts provide the extra clearance needed for thicker flanges or custom exhaust setups. Like all Stage 8 products, they feature a patented locking mechanism to ensure your exhaust remains leak-free.

Professional-Grade Security

These 12-point head bolts are crafted from premium steel and finished in nickel for superior durability. The 12-point design is perfect for tight spaces where a standard hex socket might not fit, allowing for precise torque application. The locking retainer system is the key to preventing thermal expansion and vibration from loosening your bolts over time.

  • 3/8-16 thread pitch for versatile application
  • 1.5-inch length for thicker flange requirements
  • 12-point head for improved access
  • Nickel-plated steel for maximum longevity
  • Set of 6 locking bolts and retainers

By preventing the bolts from backing out, you maintain the integrity of your exhaust gaskets, ensuring maximum exhaust flow and consistent engine performance. Whether you are building a custom race exhaust or upgrading a street vehicle, these locking collector bolts offer unparalleled reliability. Trust your exhaust security to the experts at GGCRACING.
