Dodge 5.7 HEMI Firing Order and Cylinder Numbering
Dodge/Ram 5.7 HEMI firing order 1-8-4-3-6-5-7-2 with cylinder-bank numbering, dual-plug notes, coil identification, and misfire checks.
The Gen III 5.7L HEMI firing order is 1-8-4-3-6-5-7-2. Cylinders 1-3-5-7 are on the left/driver bank and 2-4-6-8 on the right/passenger bank, front to rear.
The Gen III 5.7L HEMI firing order is 1-8-4-3-6-5-7-2. Cylinders 1-3-5-7 are on the left/driver bank and 2-4-6-8 on the right/passenger bank, front to rear. A firing order is the sequence in which the cylinders begin their power strokes. It is not the same thing as cylinder numbering, distributor-cap clock position, or ignition-coil connector order. Confusing those references can create a no-start, violent backfire, dead cylinders, or a diagnostic trail that looks like a fuel or mechanical problem.
Use the verified order only after identifying the engine family and camshaft. Classic engines can accept camshaft swaps that change the required sequence, while modern coil-on-plug engines have no distributor cap to route. The table, bank diagram, and procedure below keep those concepts separate and show how to confirm No. 1 on compression before moving any wires.

Select each cylinder to walk through the firing order. Cylinder-bank numbering and distributor direction must match the identified engine family.
Dodge 5.7 Hemi Firing Order
| APPLICATION / ITEM | SPECIFICATION | NOTES |
|---|---|---|
| Firing order | 1-8-4-3-6-5-7-2 | Gen III 5.7L HEMI |
| Driver/left bank | 1-3-5-7 | Front to rear |
| Passenger/right bank | 2-4-6-8 | Front to rear |
| Spark plugs | Two per cylinder | Common 5.7L HEMI design |
The 5.7 HEMI uses two spark plugs per cylinder on many applications. Both plugs belong to the same cylinder event; the engine still has an eight-cylinder firing order.
Which 5.7L HEMI firing order applies?
Do not substitute the GM LS 1-8-7-2-6-5-4-3 order or infer an order from cylinder-deactivation numbering. This distinction matters because the engine can look nearly identical from above. Treat the camshaft or engine assembly as the authority when parts have been mixed. A firing order cast into an intake, copied from a generic decal, or remembered from another V8 is not enough to identify a modified engine.
The application table separates the order, cylinder banks, and ignition-system notes. Read all columns before routing. The first number in 1-8-4-3-6-5-7-2 is cylinder 1, but the physical No. 1 terminal can appear in different clock positions when a distributor has been installed on a different gear tooth.
Bank numbering and verification on the 5.7L HEMI
Cylinder numbering uses odd cylinders on the driver/left bank and even cylinders on the passenger/right bank.
The 5.7 HEMI uses two spark plugs per cylinder on many applications. Both plugs belong to the same cylinder event; the engine still has an eight-cylinder firing order.
Dodge 5.7L HEMI specifications can change by model year, engine, platform, wheel, and installed component. Confirm the VIN or engine identity, part numbers, fastener condition, and the current manufacturer instructions before service.
Procedures used with this specification
These steps are the same for every vehicle in this family, so they are documented once rather than repeated on each page. The values above remain specific to this Dodge 5.7L HEMI.
