Engine family first

Crankshafts are built around specific engine families, such as small block or LS-style layouts. Confirm the exact engine family and block details before comparing other features.

Forged or billet

Forged and billet crankshafts differ in how they are made. Confirm construction against the manufacturer specification and treat it as one factor alongside the stroke and your intended engine build.

Stroke and reference codes

Stroke, journal and balancing details matter for the rest of your rotating assembly. Match the listed part reference to your build plan, and verify any unclear make wording with the supplier first.
