Wiring Kits - Alternator Upgrade - 6.0L - 7.3L - Duramax

When purchasing a new high output alternator, upgrading the charge cables is a smart move. Your factory wiring is engineered specifically for the vehicle's stock alternator output. When a high output alternator is installed, the stock wiring is simply unable to effectively transfer the added power the new alternator generates.  

By upgrading the wiring, your vehicle’s charging system is better able to keep the batteries, the FICM and other various accessories running at their best without any difficulties of getting the power they need.

Long term Ford owners come to notice that it’s always the passenger side battery that fails first (requiring them to shell out for two new batteries). Why? This is because both the starter and glow plugs are hard-wired to the passenger side battery. Migrating to our Deluxe cable kit adds a 4/0 interconnect wire – we’re talking nearly an inch in diameter worth of copper here – to allow the driver's side battery to play an active role in helping the passenger side battery absorb these loads. 

Consider also swapping your batteries between their locations a couple times a year to even the playing field even more!

Complete and basic wire kits are to be used with factory wiring and NOT replace factory wiring.
