94mm Bore Extra Long Barrels - Type 1 Engines

These extra-long 94mm barrels are engineered specifically for high-performance Type 1 engine builds where longer stroke crankshafts and/or longer connecting rods are used. At 0.8 inches longer than stock, they provide additional cylinder length to compensate for increased engine deck height—allowing you to achieve perfect combustion chamber geometry without stacking shims or compromising engine integrity.

Designed for use with all 94mm Type 1 pistons, these barrels are the ideal solution for stroker builds, performance engines, and custom long-rod combinations. Each cylinder features deep, well-defined cooling fins, providing significantly improved heat dissipation—essential on larger displacement or high-output engines where thermal control becomes increasingly important.

A key benefit of these cylinders is their machinable design. They are intentionally supplied extra long so that the machinist can trim them to the exact length needed for your build, allowing you to obtain the correct deck height without the usual trial-and-error stacking of barrel shims. This eliminates sealing issues, improves stability, and ensures a more precise and durable engine setup.

Perfect for:

• Long-stroke crank builds (82mm, 84mm, 86mm and beyond)

• Long-rod engine combinations

• Large-capacity performance engines

• Builders wanting exact deck-height control

Quantity:

Sold as a set of 4 barrels only (no pistons included).

These cylinders are a premium choice for serious engine builders who want precise control over compression height, improved cooling, and a clean, shim-free installation—ideal for creating a reliable, powerful, and well-engineered stroker motor.
