Attention! This is a B-Stock, Display or Show Product

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 offer the same high-output performance as new alternators at a reduced price, making them a great value for budget-conscious customers.

B-stock alternators are sold with a 90 day warranty. No Returns, all sales on B-Stock products are final.

The discounted prices are only valid on our website and do not qualify for any special promos, dealers, distributors or codes. We’re unable to honor these discounts for phone orders or anywhere else as these are meant to be a quick and simple alternator purchase for our customers.

These alternators are built to spec and are not applicable for modifications such as paint, clocking, pulley changes, harness swapping or regulator upgrades.

Please Note: This is a version one stands and do not include all provisions (Bolt holes are missing) required for some of the accessory kits we now offer.
