Forged Crankshafts (Waterboxer)

GoWesty Forged Waterboxer Crankshafts. Need more torque and displacement? These longer-stroke cranks are the foundation for big-bore builds with real-world drivability and off-grid reliability. Whether you're building a weekend warrior or a full-blown overland machine, GoWesty’s forged crankshafts are the bulletproof backbone your engine deserves. Crafted specifically for the VW waterboxer platform, each crankshaft retains all critical OEM specs—journal sizing, center-to-center distances, threaded holes, keyways—ensuring a precise fit into your engine block.* But we didn’t stop at matching specs—we matched the soul of the original. We were also careful to duplicate these two very important aspects of the original Volkswagen crankshaft design: Forged: Just like the original VW crankshaft, ours are made in a dedicated forging die. That means superior grain structure, greater strength, and long-lasting durability under load. Built-in “mini flywheels” design: A unique feature of the original waterboxer crankshaft, preserved in our version for authentic performance and optimal balance.

Available stroke lengths: GoWesty Forged cranks are available in two larger strokes: 79.5mm: This is the stroke we use in our 2300cc engine 84.5mm: This is the stroke we use in our 2450cc and 2700cc engines Note: The original 1900cc crankshaft has a stroke of 69mm, and the 2100cc crankshaft has a stroke of 76mm. *Engine block, connecting rod, and camshaft modifications are necessary to accommodate the longer stroke. Professional installation required.
