ARP 135-6022 High Performance Connecting Rod Bolt Kit Chrome Moly - 8740

The ARP 135-6022 connecting rod bolt kit delivers the legendary strength and reliability that has made ARP the choice of professional engine builders and racers worldwide. This 2-piece high-performance kit features 8740 chrome moly construction, providing the critical strength needed in the weakest link of any connecting rod assembly.

Superior Manufacturing Process:

• Forged in-house using premium quality materials for consistent strength
• Heat-treated on vertical racks ensuring complete 360-degree penetration
• Threads rolled after heat-treatment for up to 10 times greater fatigue strength
• Precision CNC-machined to exacting tolerances for perfect fitment
• Each bolt proudly stamped with the ARP name as assurance of quality

8740 Chrome Moly Material: This proven alloy steel offers excellent toughness with adequate fatigue properties for most racing applications. As a quench and temper steel, 8740 chrome moly delivers tensile strengths between 180,000 and 210,000 psi, making it a cost-effective solution for applications where bolt strength appropriately matches anticipated loads with a proper safety margin.

Wave-Loc Technology Benefits:

• Wave-Loc surface contacts rod and cap for optimal alignment and reduced fluctuating stress
• Provides interference fit of .001 to .005 inches for all OEM connecting rods
• Superior material grain flow compared to knurled bolts that create stress risers
• Virtually eliminates galling and scoring through smooth contact design
• Accommodates wide range of factory rod bolt hole tolerances

Maintenance Note: Monitor bolt stretch regularly and replace when permanent elongation reaches .0005 inches to ensure continued reliability and performance.
