A starter that drags leaves you stranded, wastes time, and tests your patience – especially when the 5.7 Hemi in your 2012 Ram is slow to fire. The right replacement means instant engagement, proper clearance, and a part that bolts in without filing or shimming.
I’m Amir — the founder and writer behind Four Wheel Ask. I’ve spent years analyzing component specifications, cross-referencing OEM part numbers, and compiling owner feedback from thousands of real-world installations to separate reliable parts from quick failures.
These carefully selected starters combine proven reliability, fitment, and balanced costs to define the best 2012 ram 1500 starter for any build budget.
How To Choose The Best 2012 Ram 1500 Starter
Your 5.7 Hemi needs a starter that delivers consistent 1.4 kW of cranking power through 10 teeth engaging the flexplate. Starters for the ’12 Ram share the same bolt pattern and clocking across most model years, but subtle differences in pinion depth and electrical connector orientation can cause fitment headaches if you ignore the OEM part number supercessions.
Power Rating & Tooth Count
Most aftermarket units offer 1.4 kW (about 1.9 hp) with 10 teeth clockwise rotation – the stock spec for the 5.7L V8. Dropping to a 1.2 kW starter will still crank the engine but may struggle in cold weather or with higher compression. Verify the tooth count: a 9‑tooth unit won’t mesh correctly.
Warranty & Quality Indicators
A one-year free-replacement policy is the standard for entry-level builds, while two-year warranties often signal better solenoid coatings and longer brush life. OEM Mopar units carry a reputation for longevity, but several aftermarket suppliers now use IATF 16949 certified lines and rigorous end‑of‑line testing.

In‑Depth Reviews
1. A-Premium Starter Motor (17948)
The A-Premium 17948 matches the factory 1.4 kW output and 10‑tooth clockwise rotation exactly. Owner reports across 2011–2020 Ram 1500s with the 5.7L Hemi consistently note bolt‑on fitment without any mods. The copper winding construction and one‑year unlimited‑mileage warranty provide a solid safety net for daily drivers.
Multiple verified reviews mention the electrical connector requiring a slight orientation tweak on certain years – a minor detail that is easily overcome with a small length of wire loom. Once installed, the starter engages instantly and the solenoid holds engagement through repeated hot starts.
Given the fitment coverage, component quality, and owner satisfaction rate, this unit strikes the best balance between cost and reliability for the majority of 2012 Ram owners. The one‑year guarantee covers the part itself, though labour is not included – typical for this price tier.
What works
- Exact 1.4 kW power rating matches OEM spec
- Broad vehicle compatibility across many Ram/Jeep models
- One‑year warranty with good customer feedback
What doesn’t
- Connector orientation may differ on a few build dates
- No mounting hardware included
2. OEG Parts Starter (56044736AC)
The OEG starter carries the popular 56044736AC cross‑reference and fits 2009–2020 Ram 1500s with the 5.7L, as well as Durango and Jeep Grand Cherokee applications. Owner reviews highlight the straightforward swap – the unit bolts directly to the bell housing and the electrical plug clicks in without fuss.
Some users note that the shield mounting holes are slightly undersized, requiring a gentle ream or simply leaving the shield off – a common compromise in this price bracket. The solenoid response has been described as “crisp,” with no hesitation during cold starts.
Given the sub‑70‑dollar price point and the positive fitment record across hundreds of units, this is the strongest budget‑conscious choice. The one‑year warranty provides peace of mind for the long haul.
What works
- Excellent parts‑store price without sacrificing reliability
- Broad OE number coverage (56044736AC, M000T23271, etc.)
- Fast shipping and consistent packaging
What doesn’t
- Shield holes may need slight adjustment
- No mounting bolts supplied
3. BDELI SMT0245
BDELI’s SMT0245 is rated at 1.2 kW – slightly lower than the stock 1.4 kW, but verified owners of 2005–2008 Hemi Rams report it fires the truck reliably even after long periods of disuse. The factory is IATF 16949 certified, a strong indicator of quality control in the production process.
Real‑world installs show the starter looks identical to the OEM unit and accepts factory bolts without modification. A handful of reviews note that the lower power output becomes apparent in sub‑freezing temperatures, where the engine turns over a fraction slower than the OE unit.
For those who do not regularly experience extreme cold and want a part that costs significantly less than local parts store remanufactured units, the BDELI offers impressive value. The one‑year free‑replacement warranty adds a respectable safety margin.
What works
- ISO 9001 / IATF 16949 certified production
- Direct visual match to factory starter
- Excellent feedback from warm‑climate owners
What doesn’t
- 1.2 kW output is below factory spec
- Cold‑weather cranking may be marginal
4. MOAUTO 17948N
MOAUTO’s 17948N delivers the full 1.4 kW in a cast‑iron housing that feels substantial in hand. The unit replaces the most common part numbers (56044736AB, M000T20972, etc.) and fits Ram 1500, 2500, and 3500 models with the 5.7L Hemi.
Owner reviews are positive across multiple platforms – both Ram and non‑Ram owners praise the easy installation and prompt start‑up. One minor critique appears around the seal quality where the solenoid meets the housing; a dab of dielectric grease is recommended for peace of mind.
For roughly the same price as the BDELI but with the correct 1.4 kW output, the MOAUTO edges ahead for those who want full power without stepping up to the A‑Premium.
What works
- Full 1.4 kW output equals factory power
- Robust cast‑iron construction
- Broad cross‑reference list
What doesn’t
- Solenoid seal could be tighter
- Some units shipped with loose packaging
5. Mopar 56044736AC
The genuine Mopar 56044736AC is the exact part that left the factory on your 2012 Ram 1500. Build quality is first‑rate – the solenoid casting, brush pack, and gear reduction are designed to the original Chrysler tolerances. Owners report a noticeably stronger crank speed compared to a worn‑out original unit.
However, reliability has been mixed in the long term: one verified review noted failure after 2.5 years and 15,000 miles, resulting in a tow bill. While that is an outlier, it does suggest that modern Mopar starters are not immune to early failure. The higher price tag (roughly triple that of aftermarket equivalents) forces a harder value calculation.
If you prefer zero guesswork in fitment and are willing to pay a premium for the brand, the Mopar starter will install perfectly every time. For most budget‑conscious owners, the aftermarket options offer comparable performance at a fraction of the cost.
What works
- Guaranteed OE fit and finish
- Power delivery matches factory fresh unit
- Made in USA according to packaging
What doesn’t
- Costs several times more than aftermarket equivalents
- No better warranty than budget competitors
- Occasional premature failure reported
6. SZKAIDAG 19616N
SZKAIDAG’s 19616N is built with a focus on quiet operation – the gear box and armature are precision‑machined to reduce whine during engagement. Power output is 1.3 kW, which is 0.1 kW below the factory spec, but owners of Ram 1500s, Grand Caravans, and Jeeps confirm that the starter still spins the 5.7L Hemi without hesitation.
The two‑year warranty is the best in this comparison, indicating the manufacturer’s confidence in the brush pack and solenoid durability. Note that this starter is primarily listed for V6 applications (3.6L and 3.2L), so compatibility with the 5.7L Hemi is limited to models that share the same bell housing pattern – always double‑check your VIN before purchase.
For owners of the correct vehicle platforms who value a quieter cabin and longer warranty coverage, the SZKAIDAG is a solid play. The 1.3 kW output is sufficient for daily use in all but the harshest climates.
What works
- Two‑year warranty beats most competitors
- Noticeably quieter than stock unit
- Precision machining on gear engagement
What doesn’t
- 1.3 kW is below the recommended 1.4 kW for 5.7L
- Not a direct match for all 2012 Ram Hemi applications – verify fitment
7. Start‑X Remote Starter Kit
The Start‑X BA‑CH4‑RAM is not a replacement starter motor – it is a T‑harness remote start system that integrates with your factory key fob. Press lock three times and the truck fires up remotely, pre‑warming the cabin and clearing ice in winter. The module is pre‑flashed for 2009–2012 gas Ram 1500/2500/3500 models with key ignition.
Installation time is frequently reported as under ten minutes: locate the OBD2 port and the main harness connectors behind the dash, plug the T‑harness in series, and zip‑tie the module. The only common complaint is the poor quality of the included zip ties – easily substituted. Range is limited to your factory fob’ range, but a range extender kit is available separately.
If you are happy with your current starter’s performance but want remote start capability without splicing wires, this kit delivers exceptional convenience for the price. It does not affect the starter motor itself – it only sends the crank signal.
What works
- Genuine plug‑and‑play, no wire cutting
- Quick install with clear video guidance
- Uses existing factory key fob
What doesn’t
- Not for diesel or push‑to‑start vehicles
- Included zip ties are very brittle
- Range limited by factory fob transmitter strength
Hardware & Specs Guide
Power Output (kW)
The factory specification for the 5.7L Hemi is 1.4 kW. Starters below this rating (1.2–1.3 kW) may still work in temperate climates but can struggle during cold starts when battery voltage drops. Pay attention to the wattage listed – many aftermarket units advertise 1.4 kW but actually draw that only at peak; sustained cranking is usually lower.
Tooth Count & Rotation
All Hemi starters use 10 teeth with clockwise rotation. A 9‑tooth unit will not mesh and can damage the flexplate. Clockwise is standard for the Ram; counterclockwise units exist for other engines. Always verify “10T CW” in the product description.
Warranty Length
One‑year free‑replacement is typical for budget and mid‑range starters. Two‑year warranties (as found on the SZKAIDAG) suggest higher manufacturing confidence. OEM Mopar relies on brand reputation rather than extended warranty – check the manufacturer website for specific terms.
Fitment Verification
Although the 2009–2012 Ram 1500 chassis share the same bell housing pattern, changes in the electrical connector shape occurred around 2013. Use the Amazon fitment filter or compare photos of your old starter’s solenoid plug. If the connector differs, a simple adapter or wiring conversion may be needed.
