Jeep Willy 4 Cylinder Pro Series Ready to Run Distributor - Black
Upgrade your Willys Overland L4 "Go-Devil" — 2.2L/134 CID — with this Pro Series Ready-to-Run distributor, featuring an onboard circuit board ignition module paired with a magnetic pickup trigger, so there's no separate ignition box to wire in. This distributor supports Willys MB, Ford GPW, CJ-2A, and CJ-3A applications running the L-134 flathead engine.
The housing is machined billet aluminum with a hardened steel shaft, sealed ball bearing on top, and sintered steel bushing on the bottom, and rotation is counterclockwise. This distributor requires a 12-volt electrical system with an alternator and a coil rated at 35,000 volts or higher; it is not compatible with generator-based charging systems or vehicles still running an active ballast resistor in the ignition circuit — the resistor should be removed or bypassed as part of installation.
What Is a Ready-to-Run (RTR) Distributor?
An RTR distributor has the ignition control module built directly into the housing, so it fires off a single 12-volt source without needing a separate ignition box wired into the circuit. This unit pairs that onboard module with a circuit board ignition control and magnetic pickup trigger, replacing the factory Willys L-134 breaker-point distributor. The coil stays external here, requiring a coil rated at 35,000 volts or higher.
Performance Benefits
The circuit board module and magnetic pickup trigger hold timing steady without the wear and drift of a points-based system — a meaningful upgrade for these vintage military and civilian Willys Jeep engines. Mechanical and vacuum advance are both included, along with a color-matched spark plug wire retainer, vacuum advance block-off plate, and power/tachometer extension cables for a clean, complete install.
COMPATIBLE WITH
WILLYS-OVERLAND L4 "GO DEVIL"
• 2.2 L / 134 in3
NOTES
• Designed for the Willys-Overland L-134 "Go Devil" L-head (flathead) four-cylinder engine produced from 1941–1953.
• The Go Devil was phased out beginning in 1950 in favor of the F-head "Hurricane" engine — verify which engine is installed before ordering, as both displace 134 cubic inches but are not interchangeable.
• Not compatible with the Willys F-134 "Hurricane" F-head engine — that engine requires a different distributor.
• Requires a 12-volt electrical system with alternator — not compatible with 6-volt generator systems used in original military and early civilian applications.
• Ready-to-run design — no separate ignition box required.
Requires an external coil with a minimum output of 35,000V.
• Distributor gear is most compatible with cast iron hydraulic or solid flat tappet camshafts; consult camshaft manufacturer for recommended gear material before installation.
