Is your truck's charging system acting up? This is a brand new 160 Amp Alternator made for Freightliner medium and heavy-duty trucks with the Cummins 8.3L ISC engine (around 1989-1992 models). It's a direct replacement for a bunch of OEM numbers like 1117921, 1117922, and others (check the list for your specific one). The brand is OEG Parts, part number PP7685N-1. It's a 12-volt, clockwise rotation unit based on the reliable Delco 21SI design. Comes with the pulley already installed, but no mounting hardware (you'll reuse yours). It's a new part, not a remanufactured one, and there's no core charge to worry about. Made in China but built to strict specs. This alternator will keep your batteries charged and all your truck's electrical systems running strong. Perfect for owner-operators or fleet maintenance. Comes with a 1-year manufacturer warranty. Don't get stuck with a dead battery – swap in this reliable alternator and get back on the road with confidence. A solid, no-nonsense part for keeping your big rig running right.
