Tudor Dynamator C39/40 — Original Look. Modern Output. Direct Fit.

Give your classic the charging performance it deserves without spoiling the engine bay. The Tudor Dynamator C39/40 drops straight onto the original C39/C40 brackets with correct pulley alignment and a simple hook-up, delivering alternator-level output inside a period-correct body.

Direct fit: Bolts to stock mounts, keeps the factory belt line, and integrates cleanly with your existing loom and hardware. No faff, no extra brackets.

Better value than the competition: More usable amps at idle and cruise, fewer add-ons to buy, and less install time — real performance for less.

Exclusive tooling: Our own casings and end plates replicate the OE Lucas profile and finish, so only Tudor delivers this exact fit and factory look.

Period-correct appearance: Concours-friendly finish that looks like it’s always been there.

Modern reliability: Stable voltage for halogens/LEDs, heaters, electric fans, fuel pumps, and USB/phone charging — no more dim lights at idle.

Upgrade once. Keep the look. Enjoy every drive.
