*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.
The Elite series 250 amp alternator offers great output at idle RPM and excellent durability in a direct-bolt-in package. 6 phase technology, combined with massive twin rectifier assemblies and 12 diodes makes these alternators totally durable for daily use, while still maintaining great output at low RPM. These alternators will make 180 amps at engine idle speeds with a full 250 amp output at cruising speeds. This unit comes with an OEM diameter pulley, making it perfect for high RPM and racing use. NOTE: This unit may require a rectangle to oval adapter harness if your vehicle was equipped with the CS144 Heavy duty charging option from the factory. (this is not common, see thumbnail photo of the standard plug that this alternator comes with) Ask a MechMan associate for assistance if you are unsure!
