1989-1997 OBS 7.3 Battery Cables

Factory battery terminals on 1989-1997 OBS 7.3 trucks frequently corrode and fail, compromising starting performance and charging efficiency. Our premium battery cable set replaces these weak points with military-grade components engineered for superior reliability. Each set features marine-grade, oxygen-free tinned copper cable in optimized gauges: 2/0 AWG starter cable, 1/0 AWG grounds and crossover cable, 4 AWG fender ground and starter relay supply, and 12 AWG solenoid supply. Solid zinc military-style terminals eliminate corrosion at connection points, while tinned copper lugs with adhesive-lined heat shrink ensure lasting integrity. Heavy-duty, tight-weave loom provides abrasion, heat, water, acid, oil, and fuel resistance. The result is noticeably faster engine cranking, improved charging system efficiency, enhanced battery longevity, and the electrical capacity to support additional accessories.

Installation is straightforward with factory-like fit and feel. 

Includes tape, zip ties, and all necessary hardware.

Backed by a lifetime warranty.
