Product Details

ARP's premium stainless steel header bolt kit is engineered specifically for Small Block Chevy Gen III LS Series engines with 1/4" wide header flanges. Manufactured from Stainless 300 material, these bolts deliver exceptional corrosion resistance and perform reliably under extreme exhaust temperatures, making them ideal for high-performance and street applications.

Key Features:

  • Stainless 300 material rated at 170,000 psi tensile strength
  • 12-point head design allows easy socket access in tight spaces near exhaust pipes
  • M8 x .984" thread specification optimized for LS applications
  • Impervious to corrosion and heat discoloration
  • Complete kit includes 12 bolts with premium-quality washers and 12-point nuts
  • Precision-manufactured for consistent clamping force and reliable sealing

Each ARP header bolt kit includes the exact number of fasteners, washers, and nuts required for your specific application. The compact 12-point nut design provides superior engagement while allowing socket clearance near header tubes. ARP's stringent quality control ensures every fastener meets exacting tolerances for proper installation and long-term durability.
