Replacement Rod Bolts 7/16 ARP200 1.600 UHL

The MANLEY Replacement Rod Bolts 7/16 ARP200 1.600 UHL (MAN42249-4) is a high-strength fastener set designed for precision engine builds where connecting rod integrity directly impacts reliability and longevity. These 7/16-inch bolts are essential for engine builders, performance machine shops, and enthusiasts performing connecting rod replacement, upgrade, or repair on engines requiring ARP200-grade fasteners.

Manufactured from chromoly steel and processed to ARP200 specification, these bolts feature a 12-point head design and a length of 1.600 inches. This material standard is known for its superior tensile strength and fatigue resistance, making it ideal for high-revving and high-compression applications. The 12-point head geometry distributes load more evenly than 6-point alternatives, reducing fastener stress concentration.

ARP200 fasteners deliver approximately 200,000 PSI tensile strength, providing the clamping force necessary to maintain rod-to-crankshaft concentricity under sustained load and vibration. These bolts are suitable for street performance builds, off-road power units, and any engine where factory rod fasteners are being upgraded for increased reliability margin. Proper torque specification and stretch-bolt procedure are essential for optimal performance.
