Replacement 12V Alternator, 6-Groove, GM 3.6L SUVs

Replacement alternator restores stable 12V charging to help prevent hard starts, battery warning lights, dim headlights, and weak accessories. Built for precise OE-style fitment on select 3.6L SUVs, it connects cleanly to factory plugs and mounting points for a faster swap. A 6-groove pulley supports steady belt drive up to 6000 RPM, while copper windings and an aluminum housing help manage heat under daily driving.

When your vehicle shows charging symptoms—slow cranking, flickering lights, battery alerts, or intermittent accessory power—swapping the alternator can restore normal electrical performance. This unit is designed around OE reference numbers for dependable fitment and straightforward installation using factory connections. Confirm compatibility with your vehicle’s year, engine size, and OE number before purchase to avoid returns. Grab yours today and get your charging system back to dependable operation.
