The Rod Bolt Extension - 3/8 Aluminum (2) by ARP is a precision fastening component designed for engine builders and performance mechanics who demand reliability in high-stress applications. These extensions serve as spacers or adapters in rod bolt assemblies, allowing proper clamping geometry and load distribution when upgrading to ARP's premium rod fastening systems.
Machined from 7075-T6 aluminum alloy, these rod bolt extensions deliver a lightweight design without sacrificing strength—a critical advantage in rotating assembly work where excess mass increases inertial loading on the crankshaft. The 3/8-inch diameter bore matches ARP's 3/8-inch rod bolt specifications, ensuring zero tolerance stack-up during installation.
Engine builders working with big-block Chevys, small-block variants, and other platforms requiring custom rod clearance benefit most from this two-pack solution. These extensions are essential when combining ARP's premium rod fastening systems to achieve consistent clamping loads across the entire bolt load-range.
