4.7L Gen II PowerTech V8 · 2008–2013 · Trusted since 1961
4.7L Gen II Chrysler / Jeep Engine Replacement
The second-generation 4.7L PowerTech V8 arrived for 2008 with revised cylinder heads, dual-spark-plug ignition, a higher compression ratio and flex-fuel capability, bumping output to roughly 300 hp in the Jeep Grand Cherokee, Commander, Dodge Ram 1500, Dakota, Durango, Chrysler Aspen and Mitsubishi Raider. It is a stronger engine than the original, but it kept the platform's oiling sensitivity, so sludge, valvetrain wear, timing chain stretch and overheating damage still send owners looking for a replacement. Fraser's remanufactured 4.7L Gen II is engineered to eliminate those weaknesses.
- Zero-Mileage Remanufactured Build
- 2008–2013 Gen II Fitment
- Upgraded Valve Seats
- Complete Sludge Removal
- Up to 5-Yr / Unlimited Warranty
Quick Answer: Where to Buy a Remanufactured 4.7L Gen II V8
Fraser Engines, trusted since 1961, sells zero-mile remanufactured 4.7L Gen II PowerTech V8 engines for the 2008–2013 Dodge Ram 1500, 2008–2011 Dodge Dakota, and 2008–2009 Jeep Grand Cherokee, Jeep Commander, Dodge Durango, Chrysler Aspen and Mitsubishi Raider. Every engine gets complete sludge removal with oil passages restored, remanufactured heads, and new pistons, rings, bearings, timing chains, guides, tensioners and oil pump.
The Gen II does not interchange with the 1999–2007 4.7L, so Fraser confirms your engine by VIN. The Fraser Advantage™ option adds upgraded valve seats, all applicable TSB updates, and a 5-year / unlimited-mile warranty plus 1 year of free No-Fault. Call 800-731-3177 (press 1 for sales).
4.7L Gen I vs. Gen II: Which Do You Have?
The two 4.7L engines do not interchange
If your vehicle is a 2008 or newer, it needs a Gen II engine. A 1999–2007 Gen I 4.7L won't work because the heads, ignition and compression are different. Looking for the earlier engine? See our 1999–2007 4.7L Gen I page.
| 4.7L Gen I | 4.7L Gen II | |
|---|---|---|
| Model years | 1999–2007 | 2008–2013 |
| Cylinder heads | Original design | Revised design |
| Ignition | One spark plug per cylinder (8) | Dual spark plugs per cylinder (16) |
| Compression | Lower | Higher |
| Fuel | Gasoline | Flex-fuel capable |
| Output | About 230–265 hp | Roughly 300 hp |
| Interchangeable? | No. Fraser confirms by VIN before shipment. | |

4.7L Gen II fitment matters
Vehicle Applications and VIN-Based Fitment
This Gen II 4.7L fits 2008–2013 Jeep, Dodge, Chrysler and Mitsubishi applications. The 2008-and-newer engine is not interchangeable with the 1999–2007 Gen I (different heads, ignition and compression), and fitment also varies by VIN, emissions package and sensor configuration, so Fraser matches every order to your VIN before shipment.

Know the warning signs
Common 4.7L Gen II Engine Problems
These issues are why a used or junkyard 4.7L Gen II so often fails again: without correcting the root causes, the same problems come right back. Most customers start shopping after sludge-related oil pressure loss, timing chain noise, a dropped valve seat, misfires or overheating.
Valve seat failure
The Gen II heads improved on the original, but overheating can still drop a valve seat, and once it lets go it can destroy the piston, head and cylinder in seconds.
Oil sludge buildup
A sensitive oiling system turns neglected oil changes into sludge that starves the valvetrain and bearings.
Oiling system limitations
Restricted oil flow to the heads causes premature cam, lifter and rocker wear even on otherwise well-kept engines.
Timing chain wear
Chains, guides and tensioners stretch and fail over time, producing rattle, timing faults and rough running.
Overheating damage
Heat-related stress warps cylinder heads, weakens valve seats and damages internal components.
Misfires and dual-plug ignition issues
16 spark plugs and coils mean more places for misfires to hide. Persistent misfires after tune-ups often point to compression loss or head damage.
Diagnose first
Repair or Replace? Signs You Need a 4.7L Gen II Engine
Some 4.7L issues can be repaired externally, but a dropped valve seat, sludge-related oil pressure loss, internal noise, low compression or severe overheating make a replacement engine the better long-term repair.
- Knocking, ticking, rattling or internal noise
- Overheating damage or repeated coolant loss
- Low compression or failed leak-down test
- Misfires that continue after ignition and fuel repairs
- Timing chain rattle or timing fault codes
- Oil pressure warnings, sludge or metal in the oil
- Coolant mixing with oil or a failed head gasket
- Replacement recommended by a licensed repair shop
True remanufacturing, not a budget rebuild

Know the difference
Used 4.7L Gen II vs. Low-Cost Rebuild vs. Fraser Remanufactured
A used 4.7L Gen II may seem like the lower-cost option, but it comes with unknown wear, hidden sludge and the same factory design flaws that caused the failure in the first place. Fraser Advantage™ engines are fully remanufactured, upgraded and tested, the superior choice for long-term value and dependability.
| Feature | Used Salvage Engine | Low-Cost Rebuild | Fraser Remanufactured |
|---|---|---|---|
| Internal mileage | Prior service mileage; unknown | Varies | Zero miles since remanufacture |
| Factory updates (TSBs) | None | Rarely | All applicable updates applied on Fraser Advantage™ |
| Valve seats & cylinder heads | Original seats, unknown history | Often reused | Remanufactured heads with upgraded valve seats (Fraser Advantage™) |
| Oiling system / sludge | Whatever the donor had | Surface clean only | Complete sludge removal; oil passages restored; improved flow |
| Internal components | Existing wear | Reuses marginal parts | New pistons, rings, bearings, timing, oil pump, gaskets and seals |
| Machine work | None | Minimal | Precision-machined block; heads pressure-tested and resurfaced |
| Fitment verification | Varies | Varies | VIN-based verification before shipment |
| Warranty | Varies / none | Short-term | 3-Yr (Standard) or 5-Yr + 1-Yr No-Fault (Fraser Advantage™) |
| Core return | Varies | Varies | Free commercial pickup with Fraser support |

Answers before you order
4.7L Gen II Engine Replacement FAQs
Will a 1999–2007 4.7L fit my 2008+ vehicle?
No. The Gen II uses different heads, dual-plug ignition and higher compression, so a 2008–2013 vehicle needs a Gen II engine. We confirm Gen I vs. Gen II by VIN.
Does the Fraser 4.7L Gen II fix the valve seat and sludge problems?
Yes. Fraser Advantage™ builds use upgraded valve seats, and every Fraser 4.7L Gen II gets complete sludge removal with oil passages restored and improved oil flow to the valvetrain.
Is a remanufactured 4.7L Gen II better than a used engine?
Yes. A used Gen II carries unknown wear, hidden sludge and the same oiling weaknesses. A Fraser 4.7L Gen II is zero-mile with sludge removed, all-new internal and timing parts, and up to a 5-year / unlimited-mile warranty with free No-Fault on Fraser Advantage™.
What are common 4.7L Gen II engine problems?
Oil sludge, restricted oil flow to the heads, timing chain and tensioner wear, overheating damage, dropped valve seats after overheating, and misfires among the 16 plugs and coils.
What's the difference between the Standard and Fraser Advantage™ options?
Standard is a fully remanufactured Gen II with sludge removal and new wear parts and a 3-year / unlimited-mile warranty. Fraser Advantage™ adds upgraded valve seats, every TSB update, a 5-year / unlimited-mile warranty and 1 year of free No-Fault coverage.
Does Fraser help verify 4.7L Gen II engine fitment?
Yes. We match every order to your VIN to confirm Gen II fitment, emissions package and sensor setup.
Can Fraser ship my 4.7L Gen II engine to my repair shop?
Yes. We ship directly to commercial repair facilities, free in the continental U.S., and coordinate free commercial core pickup after installation.
Is a No-Fault warranty upgrade available?
Yes. Optional No-Fault upgrades from 1 to 5 years are available on either option, and Fraser Advantage™ already includes 1 year of free No-Fault coverage.
