Dowel Pin - Solid Chevy V8 Crank .4386 x.813

The DURA-BOND Dowel Pin - Solid Chevy V8 Crank .4386 x .813 is a precision-engineered crankshaft alignment component designed for serious engine builders, rebuilders, and high-performance mechanics working with GM V8 platforms. This solid dowel pin serves as a critical locating and indexing element between the crankshaft and block, ensuring proper alignment during assembly and preventing unwanted rotation or misalignment under load. Whether you're performing a stock rebuild, restoring a classic Chevy engine, or assembling a modified big-block for competition, this dowel pin is an essential fastener that guarantees repeatability and structural integrity.

Manufactured by DURA-BOND, a trusted name in OEM-quality engine components, this solid dowel pin features a 7/16-inch outer diameter and 0.813-inch length, allowing it to seat precisely into corresponding holes in the Chevy V8 crankshaft and block casting. The solid construction—as opposed to hollow designs—provides superior rigidity and eliminates any risk of collapse under the extreme pressures generated during combustion and peak torque events. The tight tolerances inherent in this design ensure zero slop, maintaining crankshaft concentricity and reducing the risk of bearing wear, oil clearance issues, or crankshaft walk that can compromise engine longevity and performance consistency.

This dowel pin is ideal for mechanics and engine builders restoring or modifying small-block and big-block Chevy V8 engines from the 1950s through modern crate engine applications. Proper installation requires careful inspection of the dowel holes in both the crankshaft and block to ensure they are clean and free of debris; a light coat of assembly lube on the pin aids insertion and protects the component during initial startup. Stock one or more of these solid dowel pins in your shop for any Chevy V8 crankshaft assembly work—they are affordable insurance against misalignment-induced failure and are sold individually for precise inventory management.
