Review on GM Genuine Parts 22781131 Alternator: Reliable and High-Quality Replacement Component by Derrick Villarreal

Revainrating 5 out of 5

OEM old Duramax for spares

Perfect, used 3 weeks on my 06" LBZ One of the components I like original parts for. If it still works after 2 years it's worth it. The elastic cord that the Keeping tension on the strap made it easy to install (the strap was fairly new).

Pros
  • Alternators
Cons
  • Quality
