ARP 134-6026 Connecting Rod Bolt Kit for Cracked Cap Rods

The ARP 134-6026 is a high-performance connecting rod bolt kit designed specifically for cracked cap connecting rod designs. This 2-piece bolt kit is manufactured from ARP's proven 8740 chrome moly alloy, providing superior strength and reliability for demanding racing applications.

Why ARP Rod Bolts Are the Industry Standard:

ARP rod bolts are widely recognized as the benchmark in connecting rod fastener technology. Many connecting rod manufacturers equip their rods with ARP bolts as original equipment, understanding that the bolt has historically been the weakest link in any connecting rod assembly. With fatigue strength testing showing ARP bolts to be ten times stronger than competitor fasteners, these bolts deliver the reliability that serious engine builders demand.

8740 Chrome Moly Material:

The 8740 chrome moly steel offers excellent toughness with adequate fatigue properties for most racing applications. As a quench and temper steel, it delivers tensile strengths between 180,000 and 210,000 psi. This material provides a cost-effective solution that balances strength, durability, and value—ideal for applications where bolt strength appropriately matches anticipated loads with a suitable safety margin.

ARP Manufacturing Excellence:

• Forged in-house using only the finest quality materials
• Heat-treated using special vertical racks to ensure complete 360-degree penetration
• Threads rolled after heat-treat to provide 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
• Specially engineered for optimum reliability in cracked cap rod applications

Wave-Loc Technology Benefits:

• Wave-Loc surface contacts the rod and cap for optimum alignment and stress reduction
• Provides interference fit ranging from .001 to .005 inches for secure installation
• Superior material grain flow compared to knurled bolts that create stress risers
• Smooth contact surface virtually eliminates galling and scoring of connecting rod bores
• Accommodates wide range of factory rod bolt hole tolerances

Important Installation Note:

Monitor bolt stretch regularly and replace any bolt that has permanently elongated by .0005 inches or more to maintain optimal clamping force and reliability.

This kit includes two connecting rod bolts designed specifically for cracked cap connecting rod assemblies, providing the strength and reliability your performance engine demands.
