*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 MechMan 240 and 320 amp racing alternator for GM LS truck provides vastly improved durability over the stock large case truck alternator at a great price. This 6 phase unit cranks out over 120 amps at idle with a high-RPM friendly stock diameter alternator pulley. This alternator features twin steel internal fans and a hairpin stator for much better high RPM durability than OEM truck alternators.
The simple internal voltage regulator makes installation a snap on any engine swap application, regardless of which wiring harness you are using. Simply connect a 4 gauge positive and ground cable between the alternator and the battery, an ignition switched turn on wire to the alternator plug, and the alternator will do the rest! Twin pure copper rectifier plates and 12 huge diodes make this unit highly durable in hot / abusive racing applications.
