The Chrysler eBeam is a fully electric rear — axle drive module produced from 2023 onward. It features a single permanent — magnet synchronous motor integrated into a compact e — axle assembly. This system delivers 215 kW (288 PS) and 549 Nm of instant torque, enabling rapid acceleration and quiet operation.
Fitted exclusively to the Ram 1500 REV, the eBeam system was engineered for robust towing capability and smooth, responsive power delivery characteristic of electric…
All production years meet zero tailpipe emissions standards (US EPA Certification #AID2023eBEAM, EU Type Approval e24*2023/XX).
The Chrysler eBeam is an integrated electric drive system engineered for full-size pickup trucks (2023-Present). It combines a single permanent-magnet motor with a single-speed reduction gear to deliver instant, linear torque and robust towing performance. Designed for zero tailpipe emissions, it prioritizes efficiency and capability within a heavy-duty platform.

The Chrysler eBeam system is used in Stellantis's DT platform with rear-wheel drive configuration. This system received a significant software update in 2024, creating a distinction between pre-update and post-update vehicle behaviors. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The eBeam's primary reliability consideration is software-related behavior, with the initial regenerative braking calibration being the most documented concern. Stellantis service data indicates this was effectively resolved via the Q2 2024 OTA update. Secondary considerations include managing expectations for range under heavy load or extreme temperatures. Adherence to recommended maintenance, particularly eAxle fluid changes, is critical for long-term hardware reliability.
Analysis derived from Stellantis technical bulletins (2023-Present) and early NHTSA owner complaint data (2023-2024). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
As a new technology, long-term data is limited, but the eBeam system is based on robust, proven EV components. The primary concern (regenerative braking smoothness) was addressed via a software update. With proper care, including eAxle fluid changes and 12V battery maintenance, the system is expected to be very reliable. Electric motors have fewer moving parts than internal combustion engines.
The most documented issue was initial software calibration for regenerative braking, now fixed. Common operational 'issues' are reduced range under heavy load or extreme temperatures (normal for EVs) and 12V battery discharge if the vehicle sits unused. Mechanical issues like eAxle noise are rare if maintenance is followed.
The eBeam system is currently used exclusively in the Ram 1500 REV pickup truck. It is not used in any Chrysler-badged passenger cars. The system is a Stellantis product, powering their flagship electric truck.
Official tuning is not offered. The system's power output is managed by sophisticated software to protect the battery and drivetrain. Unauthorized modifications can void the warranty and potentially damage components. Performance is already optimized for towing and acceleration.
The EPA-estimated range is approximately 523 km (325 miles) for the standard-range battery and up to 644 km (400 miles) for the extended-range option. Real-world range varies significantly based on driving style, terrain, climate, and payload/towing. Expect less range when towing or in extreme cold.
This concept doesn't apply to electric motors. There is no timing belt or chain. If the motor or power electronics fail, the vehicle simply will not move. There is no risk of internal mechanical collision like in an interference ICE engine.
The eBeam's integrated gearbox requires Mopar® eGear 75W-85 oil. This is a specialized fluid designed for the unique demands of an electric drive unit. Using any other fluid can cause damage and is not covered under warranty. Check your owner's manual for the specific service interval.
