XS Power BIG3-RD 1/0 AWG Big 3 Upgrade Kit
Voltage dropping because the factory charging-system cables are the bottleneck? A Big 3 upgrade is where we start cleaning up the main current paths: alternator positive to battery positive, battery negative to chassis, and engine block to chassis. This kit gives you the 1/0 AWG cable and hardware for those three runs. It improves the wiring path; it does not magically create alternator or battery capacity that is not there.
