*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 typically sold with a 90 day warranty.

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.

This newly introduced CAST version of our already eye-catching Billet versions packs the same modern 6 phase hairpin technology but in a more budget friendly and paintable case!  Great for applications where you need the 200 amps at idle and 400+ amps at cruising but want to color coordinate or contrast your engine theme/look.

This 400-amp version will use a 46mm 9 rib pulley. We do this in order to facilitate multiple or custom fitments. This gives the customer the ultimate in adjustability for custom applications where a few mm's here and there add up to where you can achieve perfect belt alignment for adequate grip.

Since these CS144 style fitments are so popular and universal, we also include a universal adapter bolt/nut/spacer for ease of installations or variations in OEM and/or custom fabricated mounting brackets.

Please ensure you're using a high-quality belt, a very rigid alternator bracket with support and have at least an OEM amount of belt wrap to get the most of out of this high output alternator.

This alternator will come with a P101 harness that only needs a 12v key on/off source to operate. If higher than 14.8 voltage is desired, please see our wire harness section for voltage boosting plugs for easy and reliable voltage boosting up to 16+ volts.
