Product Overview
The 68078950AB is a Jeep OE-spec replacement alternator delivering 12V 160A output with a 6-rib (6PK) pulley, engineered for the Jeep Wrangler with the 3.6L V6 engine, model years 2012-2017. This aftermarket unit matches the original charging-system specification of these Mopar off-road platforms.
Fitted with internal regulator design, this brand-new alternator is stocked in-house with a 1-year warranty and 10-day dispatch lead-time. The 160-amp rating is factory-correct for the stock electrical load of the Wrangler, supporting climate control, heated and powered accessories, infotainment, winch pre-wiring and the battery-charge management strategy.
Key physical specs: net weight 5.9 kg, gross weight 6.2 kg, overall dimensions 240 x 180 x 170 mm, supplied inside neutral kraft inner carton.
The 3.6L V6 Wrangler Platform and 160A Charging System
The Jeep Wrangler (2012-2017) uses the 3.6L 3604 cc V6 DOHC petrol engine, which carries a significant factory electrical load including infotainment, heated and powered accessories and battery-charge management. This is why the charging system is rated at 160A rather than a lower output.
This unit is specified as 12V 160A, matching the factory charging-system specification of these platforms. The 6-rib pulley matches the original accessory-belt layout, driving alternator, water pump and power-steering pump. Installing a pulley with the wrong rib count will cause belt mis-tracking, slippage, premature belt wear and charging faults. Always cross-check against your old alternator before ordering.

Engine Compatibility and Cross Reference
This alternator fits the Jeep Wrangler with the 3.6L V6 engine, model years 2012-2017. Do not rely solely on vehicle model name for fitment validation; always verify engine code, old-part OE number, pulley rib-count and amp label on your original alternator.
| Make / Model | Engine | Year |
|---|---|---|
| Jeep Wrangler (2-Door) | 3.6L V6 DOHC | 2012-2017 |
| Jeep Wrangler Unlimited (4-Door) | 3.6L V6 DOHC | 2012-2017 |
| Trims covered | Sport, Sahara, Rubicon, 75th Anniversary (2016) | - |
Multiple Jeep and supplier OE numbers appear across production batches and regional market specifications for this same alternator family. If your original unit bears one of the listed cross-reference numbers, 68078950AB serves as a direct drop-in replacement.
What to Look for in a Replacement
Follow these five verification steps before placing your order to avoid wrong-part returns:
1. Check the amperage label on your old alternator: confirm it is rated for 160A. Different amp ratings are not interchangeable.
2. Count pulley ribs: this unit requires 6PK (6-rib). Units with a different rib count are incompatible for this accessory drive setup.
3. Confirm the engine (3.6L V6) and production year (2012-2017) of your Wrangler.
4. Match against OE / reference part numbers stamped on your original housing.
5. Weight cross-check: genuine matching unit weighs approximately 5.9 kg net; significant weight difference indicates wrong assembly.

In Practice
For technicians working on the Jeep Wrangler (2012-2017): Before removing the existing alternator, perform charging-system diagnostics. Measure battery terminal running voltage with a multimeter. Weak batteries, corroded ground connections or a faulty main harness can mimic alternator failure symptoms. Always disconnect the battery negative terminal before commencing removal work.
Take photos of wiring connectors and bolt positions during disassembly to avoid mis-routing during reassembly. Observe correct belt tension: 10-15 mm deflection when pressing the belt mid-span. Over-tightened belts accelerate alternator bearing wear; loose tension creates slipping and insufficient charging. Torque mounting bolts to Jeep workshop-manual specifications.
Inexperienced home mechanics are recommended to entrust replacement work to a qualified auto-electric repair shop. Incorrect wiring risks burning the alternator or vehicle-system components.
