Mean Green Gear Reduction Starter 6670 – 2003-2007 Ford 6.0L Powerstroke

Eliminate hard starts and hot-start problems with the Mean Green 6670 gear reduction starter. This high-performance unit delivers 100% more torque than the heavy, underpowered factory starter while drawing less current and spinning the engine faster.

Built around a 4.4:1 gear reduction and a high-speed motor, the Mean Green starter uses five precision bearings throughout the motor and gear assembly for smooth, reliable operation. Key construction details include a 3-inch tool-steel driveshaft supported at both ends, a stainless-steel externally splined pinion shaft, and a heat-resistant integrated solenoid that continues to function under extreme temperatures.

Key Benefits

• 100% more cranking power than stock
• 1/3 smaller and lighter than the OEM starter for better oil pan and header clearance
• Rotatable in 20° increments for improved exhaust header fitment
• Direct bolt-on installation – no core charge required
• Designed for 300,000-mile service life
• Backed by a 2-year unconditional warranty (1 year commercial/racing)

Fits: 2003–2007 Ford Super Duty trucks with the 6.0L Powerstroke diesel (F-250, F-350, and related chassis).

Whether you’re dealing with weak cranking, heat-soak issues, or a high-compression build, the Mean Green 6670 provides the reliable, high-torque starting performance the 6.0 Powerstroke needs.
