Product Details

ARP's High Performance Series main bolt kit delivers professional-grade reliability for competition engines. Forged from premium 8740 chrome moly steel, these main bolts feature a generous under-head radius and rolled threads that provide exceptional strength and durability. The threads are rolled after heat-treating, resulting in approximately 1000% longer fatigue life compared to conventional main bolts that are threaded before heat treatment.

Key Features:

  • 8740 chrome moly steel construction for superior strength
  • 180,000 PSI tensile strength rating, significantly stronger than Grade 8 hardware
  • Threads rolled after heat-treating for 1000% longer fatigue life
  • Generous under-head radius reduces stress concentration
  • Includes parallel-ground hardened washers for even load distribution
  • Precision-manufactured to meet professional engine builder standards
  • Direct replacement for OEM main bolts in 2-bolt applications

This complete kit provides everything needed to secure your engine's main caps with confidence, making it an essential upgrade for performance builds, rebuilds, and racing applications where fastener reliability is critical.

Ordering was easy and product arrived in a reasonable amount of time. No complaints with respect to order and delivery. Although, note my comment regarding product packaging. I ordered two each like Fram Air Filters. Both filters arrived in their original boxes, which were both placed into a single larger box for shipping. Upon arrival, the Fram boxes were severely damaged as if someone had been using them as footballs. Fortunately, the air filters within were not physically damaged. The company who shipped this order to me needs to do a better job of packaging and/or use heavier boxes to prevent damage of content.

No problems at all.
