i got a 275amp high output alternator for all NBS tahoes and yukons with the 5.3 engine, its is a 4-pin and is a direct swap. It will also fit NNBS tahoes and yukons with the 5.3 but you have to either splice a 4-pin plug on your existing wire harness or bypass the stock plug and connect directly to the fuse box. The alternator was built by Mike Singer at Singer Alternators.
