Manley Performance 42351-4 3/8-Inch ARP 2000 Rod Bolt for I-Beam Connecting Rods (Pack of 4)

Important excerpt from the ARP catalog regarding proper fastener installation: “The importance of tightening fasteners to their required preload cannot be emphasized enough. If a fastener is not preload cannot be emphasized enough. If a fastener is not tightened properly, the fastener will not apply the required preload on the application it is being used for and may become susceptible to failure. Conversely, if a fastener is over tightened and stretched too much, it becomes susceptible to failure by exceeding it’s maximum yield point.” Underhead Length: 1.600 in. - Recommended Stretch (w/ ARP Lube): .0058-.0062 in. - For I-Beam Rods - Qty: 4 Manley Connecting Rod Bolt - Replacement Parts - Cap Screws 3/8" ARP 2000 - 1.600" UHL.

• Premium ARP-manufactured rod bolts engineered for high clamp load and reliability
• Provides consistent preload when installed using recommended stretch method
• Precision thread rolling and heat treatment for maximum tensile strength
• Ideal for high-horsepower, high-RPM street and racing applications

Designed specifically for high-performance engine applications, the Manley Performance 42351-4 rod bolts are engineered to deliver exceptional clamp load and reliability under demanding conditions. Crafted from ARP 2000 material, these bolts feature precision thread rolling and heat treatment, ensuring maximum tensile strength for high-horsepower, high-RPM street and racing engines. The 1.600-inch underhead length and recommended stretch of approximately .006 inches with ARP lube facilitate proper installation, promoting consistent preload and optimal performance. Proper torque and stretch application are critical, as under-tightening can lead to insufficient clamping force, while over-tightening risks stretching beyond the bolt's yield point, potentially causing failure. These bolts are compatible with Manley I-Beam rods, including SB Chevy Tour Lite and NHRA Legal Super Stock Pro Series I-Beam, making them a reliable choice for enthusiasts seeking durability and precision in their engine builds.
