ARP 200-6208 Pro Series Rod Bolt Kit 3/8"-24 x 1.750" UHL ARP2000 8-Piece Set

Vehicle Fitment

• Universal - general replacement connecting rod bolt for steel connecting rods using a 3/8" thread and 1.750" underhead length; compatible with a wide range of OEM and aftermarket steel rods across domestic and import performance engines

Fitment Notes

• Universal replacement - not rod-manufacturer specific; always measure your existing rod bolt (thread size, underhead length, and collar diameter) before purchasing to confirm fitment
• Nuts are not included - verify your existing rod nuts are compatible or source appropriate 3/8"-24 12-point nuts separately
• Use with ARP Ultra-Torque Fastener Assembly Lubricant for accurate torque and stretch readings
• Use of a stretch gauge is strongly recommended over torque wrench for most accurate installation pre-load

Features

• Manufactured from proprietary ARP2000 alloy - rated at 200,000 psi tensile strength, far superior to OEM rod bolts
• Precision CNC-machined to exacting specifications for consistent dimensions and reliable clamping force
• Threads are rolled after heat treatment for up to 10x more fatigue strength than cut threads
• 12-point head style for maximum wrench engagement in tight engine bays
• Capable of handling the high cyclic loads and extreme stress of high-combustion performance engines
• Direct replacement for OEM and aftermarket steel rod bolts in stock, street performance, and racing applications

Product Description

The ARP 200-6208 is an 8-piece Pro Series connecting rod bolt kit designed as a general replacement for steel connecting rods using a 3/8"-24 thread and 1.750" underhead length. Made from ARP's proprietary ARP2000 alloy and rated at 200,000 psi tensile strength, these bolts are a significant upgrade over OEM hardware and most entry-level aftermarket rod bolts. Threads are rolled after heat treatment for dramatically improved fatigue life, and precision CNC machining ensures consistent dimensions across every bolt in the kit.

These bolts are ideal for engine builds that demand more from the rotating assembly - including high-RPM applications, boosted builds, and engines running significantly above stock power levels - but where a full aftermarket rod upgrade is not required. Always verify your rod's bolt hole diameter, thread pitch, and UHL before purchasing. A stretch gauge is strongly recommended over a torque wrench for the most accurate and repeatable installation pre-load.
