ARP 3AJ1.850-2C 3/8-24 x 1.850" 12-Point Connecting Rod Bolt

The ARP 3AJ1.850-2C is a precision-engineered 3/8-24 x 1.850" 12-point connecting rod bolt designed for high-performance and racing applications. Chosen by a large number of connecting rod manufacturers as standard equipment, these bolts are a mark of quality in the performance engine building community.

Key Features:

• 3/8-24 thread size with 1.850" under-head length
• 12-point head design for precise torque application
• Precision centerless-ground and thread-rolled to exacting standards
• Ten times the fatigue strength of competitive bolts
• ARP name stamped on each bolt for quality assurance
• Reduced diameter shank for optimal fatigue resistance
• Wave-Loc surface design for optimum alignment and stress reduction

ARP connecting rod bolts are engineered to withstand the extreme forces generated by high-RPM operation, where reciprocating loads create both direct tension and bending stresses. The 12-point head design allows for more precise torque application and easier access in tight engine compartments. Each bolt undergoes rigorous manufacturing processes to ensure consistent quality and performance.

Note: This is a single bolt. Most connecting rod applications require two bolts per rod. Torque specifications for aftermarket connecting rods should be obtained from the rod manufacturer, as proper installation values depend on specific rod design and clearances.
