Product Details

The ARP 135-6021 connecting rod bolt kit delivers the reliability and strength that professional engine builders demand. Manufactured from ARP's premium 8740 chrome moly steel, this 2-piece bolt kit provides the superior fatigue resistance and clamping force needed for high-performance racing applications.

Why ARP Rod Bolts Are Superior

ARP connecting rod bolts are engineered to eliminate the weakest link in any connecting rod assembly. Through advanced manufacturing processes and rigorous quality control, ARP bolts deliver up to 10 times the fatigue strength of competing fasteners. The 8740 chrome moly material is heat-treated to achieve tensile strengths between 180,000 and 210,000 psi, making it an ideal choice for most racing applications where reliability and cost-effectiveness are both priorities.

Key Features:

  • Forged in-house using premium 8740 chrome moly steel
  • Heat-treated using special vertical racks for complete 360-degree penetration
  • Threads rolled after heat-treat for up to 10 times longer fatigue life
  • Precision CNC-machined to exacting specifications
  • Each bolt proudly stamped with the ARP name as assurance of quality
  • 2-piece kit designed for specific connecting rod applications

Wave-Loc Technology (Where Applicable):

  • Wave-Loc surface design provides optimal alignment between rod and cap
  • Reduces fluctuating stress to strengthen the connecting rod itself
  • Interference fit range of .001 to .005 inches accommodates OEM rod bolt hole tolerances
  • Superior material grain flow compared to knurled bolts with stress risers
  • Smooth contact surface virtually eliminates galling and scoring

Installation and Maintenance

For maximum reliability, monitor bolt stretch regularly and replace any bolt that has permanently elongated by .0005 inches. The 8740 chrome moly material provides adequate fatigue properties for most racing applications when properly installed and maintained, offering an excellent balance of performance and value.

Awesome dealer for auto-parts. Fast shipping and they sell good products at great prices! Bought set of club racing brake pads for $15 less than anywhere else on a Saturday and they were here the following Wednesday. I'm in Memphis and it was the week before Christmas. I was very impressed and pleased!
