New 160 Amp Alternator For Chevy Suburban / Tahoe 2007-2014 – Replaces 25877026, 8301

If your Chevy Suburban or Tahoe from 2007 to 2014 is having electrical issues—dim lights, slow starts, dead battery—it might be the alternator.

This is a brand new 160-amp unit from Autoparts-leader, part number AP11259501S.

It's a direct replacement for a bunch of OEM numbers: 25877026, 15093928, 15857608, and crosses to ADR0369 and 8301.

It's 12 volts, clockwise rotation, with a 6-groove serpentine pulley included.

Regulator is internal (IR), fan type is IF, and it's engineered to meet or exceed OEM specs.

No core charge, no core required—just swap and go.

Built with quality components, tested for reliability, and backed by a 1-year warranty.

If you're hauling or towing, you need a solid electrical system.
