LUG - COPPER-4GA-3/8 STUD (CAT CT301704)

A damaged lug can interrupt electrical current flow, leading to intermittent starter or charging system faults. During inspection, a corroded or loose lug often reveals itself through voltage drop or heat discoloration. Keeping a lug in sound condition helps maintain a reliable low-resistance connection in high-amperage circuits. This aftermarket replacement part references CAT as the OE maker and carries the cross-reference part number CT301704. It is a copper lug sized for 4-gauge cable with a 3/8-inch stud hole.
