Rod Bolt Kits

Connecting rod bolts are among the most highly stressed fasteners in an engine, clamping the rod cap to the rod under extreme tensile and fatigue loads. Whether you're rebuilding a stock engine or assembling a high-horsepower race motor, the right rod bolt kit is essential for long-term reliability.

  • Manufactured from premium alloy steels such as 8740 chromoly, ARP2000, or L19 — offering high yield strength and durability.
  • Heat-treated and precision-ground for consistent clamping force and accurate torque readings.
  • Commonly feature rolled threads to eliminate stress risers and improve fatigue life.
  • Available in a range of under-head lengths, thread pitches, and grip lengths to match OE and aftermarket rods.
  • Kits often include matched pairs of bolts, nuts, and hardened washers; some include break-in lubricant.

Select a rod bolt kit that matches your connecting rod's specifications and your engine's power goals. Browse our collection to find the right fasteners for your build.
