ARP 200-6526 Connecting Rod Bolt Kit with Washers L19 Steel

The ARP 200-6526 is a high-performance connecting rod bolt kit designed as a direct replacement for aluminum connecting rods manufactured by Venolia, Brooks, KB, and BRC. This 2-piece kit features ARP's premium L19 steel construction and includes washers for complete installation.

L19 Steel Construction:

L19 is a premium steel alloy processed to deliver superior strength and fatigue properties compared to standard 8740 chrome moly and ARP2000 materials. Capable of delivering clamp loads at 260,000 psi, L19 is engineered for high-stress applications where inertia loads exceed the capabilities of conventional materials. This makes it ideal for short track and drag racing applications where extreme cylinder pressures and high RPM operation demand maximum reliability.

ARP Manufacturing Excellence:

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

Important Installation Notes:

L19 steel requires special care during installation and use. Like most high-strength quench and temper steels, L19 must be kept well-oiled and protected from moisture to prevent stress corrosion. It is critically important to monitor bolt stretch and replace bolts when they have permanently elongated by .0005 inch to maintain proper clamping force and prevent failure.

Kit Contents:

• 2 connecting rod bolts manufactured from L19 steel
• Washers included for proper installation

ARP rod bolts have been proven through extensive testing to deliver ten times the fatigue strength of competing fasteners, making them the preferred choice of connecting rod manufacturers and professional engine builders worldwide.
