Product Overview
Copper lugs sized for 2/0 cable with a 5/16" stud hole — the standard for alternator output, battery, and ground terminations in a high-current system.
Solid copper matters here. A high-output alternator build pushes serious current through every termination, and a poor-quality lug becomes the hot spot and the voltage drop in your whole electrical run.
Crimp them properly with a hammer or hydraulic lug crimper and finish with adhesive-lined heat shrink for a connection that will outlast the vehicle. Ten per pack covers a typical big-three plus alternator and battery run.
