Currently, there are no aftermarket alternators on the market
for the Corvette applications. Most of the late model
Corvette distributors carry chromed remanufactured stock
alternators for around $600. The C5 and C6 Corvettes, along
with the 2010+ Camaro, have a unique bolt pattern, and are equipped

Our billet racing units produce more amperage than the stock 110 or
145 amp GM alternators, at ALL rpms, ESPECIALLY at idle. Our

attractive billet aluminum housing, have 1 lb less rotating mass,
and use 3 less HP at full load.
Essentially, we use OEM 2010 Corvette ZR1 alternator internals,
assembled in custom Billet Aluminum housing to fit the LS1,
LS2, LS3 and LS6 equipped vehicles. We also equip our alternators

unit, OR “1 wire” hookup, which is popular for customers who
have gone to a standalone EFI system and no longer have wiring for
the plug and play alternator.
All of our units are built in the USA, with more than 85% USA
sourced parts, and feature a 5 year performance guarantee.
Chrome and Black Anodized finishes are

special order, for an additional $65.00. Please call for special
