Dowel Pin GM Adj .014

The Lakewood Dowel Pin GM Adj .014 is a precision bellhousing alignment component engineered for General Motors V6 and V8 engine platforms. Designed for builders and technicians who demand repeatable, factory-grade accuracy during engine-to-transmission assembly, this adjustable dowel pin eliminates guesswork in critical alignment work. Whether you're rebuilding a classic muscle car, restoring a vintage pickup, or servicing modern GM powerplants, proper bellhousing concentricity directly impacts driveline longevity and shift quality.

This extra-long dowel pin features a 0.621-inch diameter steel construction with a calibrated 0.014-inch offset adjustment capability, allowing fine-tuned alignment compensation for worn or warped mounting surfaces. The EZ-adjustable design permits quick field correction without full teardown, reducing labor time on the bench. Supplied as a pair, these pins work in tandem to locate the bellhousing concentrically to the crankshaft centerline—a critical tolerance that prevents vibration, bearing wear, and transmission input-shaft runout. Steel construction ensures durability under repeated assembly and disassembly cycles.

Professional engine builders, restoration shops, and serious enthusiasts rely on Lakewood precision tooling to achieve OEM-equivalent results on the bench. Installation is straightforward: position both dowel pins in their respective bellhousing holes, then adjust the offset to achieve zero runout when measured against the crank flange. Compatible with both carbureted and fuel-injected GM V6/V8 applications from classic through modern generations, these pins are an essential addition to any builder's alignment kit when precision matters and cutting corners is not an option.
