ARP 142-6001 Connecting Rod Bolt Kit Chrome Moly - 8740

The ARP 142-6001 is a high-performance connecting rod bolt kit manufactured from premium 8740 chrome moly steel. Designed to eliminate the weakest link in any connecting rod assembly, these fasteners deliver the reliability and strength demanded by serious racers and engine builders.

Why ARP Rod Bolts Are Superior:

ARP rod bolts are engineered to provide up to ten times the fatigue strength of competing fasteners, making them the choice of leading connecting rod manufacturers worldwide. Each bolt is forged in-house from the finest materials and undergoes rigorous quality control to ensure consistent performance under extreme conditions.

8740 Chrome Moly Material:

The 8740 chrome moly alloy offers excellent toughness and adequate fatigue properties for most racing applications. This quench and temper steel delivers tensile strengths between 180,000 and 210,000 psi, providing reliable clamping force with outstanding durability. It represents the most cost-effective solution for applications where bolt strength is matched appropriately to anticipated loads.

Key Features:

• Forged in-house using only premium quality materials
• Heat-treated using special vertical racks for complete 360-degree penetration
• Threads rolled after heat-treat to provide up to 10 times longer fatigue strength
• Precision CNC-machined to exacting specifications
• Each bolt proudly stamped with the ARP name as assurance of quality

Wave-Loc Technology (Where Applicable):

• Optimizes alignment and reduces fluctuating stress to strengthen the rod itself
• Provides interference fit (.001 to .005 range) despite wide factory tolerances
• Superior grain flow compared to knurled designs that create stress risers
• Eliminates galling and scoring through smooth surface contact

Installation Note: Monitor bolt stretch carefully and replace any bolt that has permanently elongated by .0005 inches or more to maintain optimal performance and safety.
