Dowel Pin Extra Long Bellhousing Steel (Pair)

The Dowel Pin Extra Long Bellhousing Steel (Pair) from WEHRS MACHINE is a precision alignment component engineered for engine-to-transmission interfaces on GM applications. These dowel pins function as critical locating devices, ensuring proper bellhousing concentricity and preventing misalignment that can lead to vibration, bearing wear, and drivetrain damage. Designed for builders and mechanics who demand OEM-grade reliability, this pair delivers the exact fitment and durability required in high-performance and stock engine builds.

Manufactured from hardened steel, these dowel pins feature an extended 1.500-inch length and 0.625-inch diameter to provide maximum engagement and load-bearing capacity in bellhousing mounting surfaces. The hollow design reduces weight while maintaining structural integrity, and the precision tolerances ensure zero-play fitting that eliminates the guesswork during engine assembly. Steel construction resists corrosion and maintains dimensional stability across thermal cycling, making these pins suitable for both street and competition environments where precision alignment is non-negotiable.

These dowel pins are ideal for GM engine builders, transmission specialists, and DIY enthusiasts performing complete engine rebuilds or bellhousing replacement. Installation is straightforward—simply press the pins into the engine block's prepared holes before mounting the bellhousing to guarantee perfect alignment. The pair configuration ensures both mounting points are addressed simultaneously, reducing assembly time and the risk of partial installation. Whether you're rebuilding a Chevy Small Block, Big Block, or LS platform, WEHRS MACHINE dowel pins provide the precision foundation upon which a reliable drivetrain is built.
