Mechman B-Stock alternators are factory-refurbished units that may have been lightly used, returned, or reconditioned. They may show minor cosmetic imperfections like scratches or finish blemishes but are fully tested to meet Mechman’s strict performance and reliability standards. These units deliver the same high-output performance as new alternators at a reduced price.

Ships in 3–5 business days (processing). “In Stock” means available in our inventory; it does not mean same-day shipping.

Warranty: B-Stock alternators include a 90-Day Functional Warranty only. Warranty covers performance (not cosmetics or labor), is non-transferable, and all sales are final — no returns or exchanges. An optional extended warranty is available beginning at $49.99.

Restrictions: No Modifications Allowed. No paint, pulley swaps, clocking, harness changes, or regulator upgrades. If customization is required, please purchase a new retail alternator.

Pricing: Standardized B-Stock pricing applies to all orders (web or phone). Not eligible for promotions, dealer/distributor discounts, or codes.

Returns/Warranty page add: B-Stock Alternators: 90-Day Functional Warranty only (performance coverage; cosmetic imperfections and labor are not covered). Warranty is non-transferable. All B-Stock sales are final no returns or exchanges.

The S series of 6 phase alternators offers incredible output in a compact and durable package. 12 diodes, (instead of the normal 6 diodes) and twin rectifier plates with outstanding airflow ensure long service life, even in severe conditions. A side output stud and seamless rear cover with a side output plug allow for better clearance from the back of the alternator to the front of the engine and a smooth appearance. 

A single wire on the provided pigtail gets connected to any ignition switched 12V+ source to turn the alternator on and off with the ignition switch. Simply run a properly sized positive and ground cable from the alternator to the terminals of the battery and the alternator will work perfectly, regardless of what kind of wiring harness you have.
