LT1 Impala SS Caprice Corvette 5.7L 250-390 Amp Large Case Hairpin Brand X High Output Alternator

Sold by AudioSellerz.com

Important Before Ordering:

This high output alternator is sold in the standard factory color unless custom powder coating is selected before checkout. Product photos may show a custom color or finish for example purposes only. If you do not select custom powder coating, your alternator will be built and shipped in the standard factory finish.

This alternator is hand-built, bench tested, and shipped after production is complete. Average build time is typically 2-4 weeks before shipment. Because each alternator is built to order for your vehicle and application, it does not ship immediately after purchase.

Please make sure all vehicle information, amperage options, plug type, and any custom options are selected correctly before placing your order.

If you need a direct replacement high output alternator for your LT1 powered vehicle, this Brand X large case hairpin alternator is built for Impala SS, Caprice, and Corvette 5.7L applications that need more charging power for car audio, added accessories, and higher electrical demand. This is a CS144 direct replacement that bolts on and plugs in as a replacement for the stock alternator.

This alternator includes a plug and play adapter so you can wire it in without modifying the factory harness, and it is set to charge at 14.8v. That makes it a strong option when you want more output without turning the install into a headache.

Output options include 250 amp large case hairpin, 270 amp large case hairpin, 370 amp large case hairpin, and 390 amp large case hairpin variants, giving you multiple choices depending on how much charging power your setup needs.

Important Installation Notice
A Big 3 upgrade is required when installing a high output alternator. Factory wiring is not designed to support the increased current demand of a high amp alternator or heavy duty alternator upgrade. Failing to upgrade the charging and ground wiring can create excessive heat, voltage drop, and alternator damage, including rectifier failure. Damage caused by improper wiring or failure to complete the Big 3 upgrade is not covered.
