Description
A1391 Replacement Alternator
Choose a replacement by comparing the A1391 alternator and its Lucas reference, LRA01391, with your existing unit. An alternator maintains battery charge and supplies electrical power while the engine runs. Confirm the vehicle application with the team before ordering.
Key Features and Benefits
- Single-groove pulley: check belt profile and alignment against the existing unit.
- 3 mounting holes: compare the fixing pattern and unit position.
- M6 B+ terminal: check the connection against the original unit.
- Lucas LRA01391 reference: a starting point for identifying the replacement.
Compatible Vehicles and Applications
Quote A1391 and LRA01391 with your vehicle details so the team can check the application. Compare the original part number, engine and physical unit rather than relying on a general model description.
These are selected applications, not the complete fitment list. Check the detailed vehicle compatibility table, engine code and production year, then compare the original unit before ordering.
OE Numbers and Cross-Reference Information
The following cross-reference numbers are associated with A1391. Compare them with the original unit and technical specifications; a number match alone does not establish vehicle compatibility.

When Should You Replace Your Alternator?
