The Mean Green MG6696 gear reduction starter is designed as a high-torque, direct bolt-in upgrade for 2011–2022 Ford 6.7L Power Stroke diesel trucks. It targets owners who need more reliable cranking performance than the factory starter can provide, especially in cold climates, high-mileage work trucks, or performance builds with increased cylinder pressure and tighter engine setups.
Using a 4.4:1 gear reduction, the starter multiplies the torque output of its high-speed electric motor, delivering up to 100% more cranking power compared to a stock, full-size unit. This extra torque helps 6.7L Power Stroke engines fire quickly even with higher static compression, heavy towing workloads, or larger injectors and aggressive tuning, reducing strain on batteries and cables during repeated start cycles.
Inside, the MG6696 uses a 3" tool steel driveshaft supported by bearings at both ends, a stainless steel pinion shaft that is externally splined to an internally splined driveshaft, and a motor armature that is also supported by bearings at each end. Altogether, there are five bearings in the motor and gear assembly, which helps maintain alignment, reduce friction, and extend service life for daily driven work trucks and heavy towing applications.
The starter’s housing is approximately one-third smaller than the stock unit, improving clearance around the oil pan, up-pipes, and aftermarket exhaust or chassis components. An integrated solenoid keeps the package compact and simplifies wiring, while the overall design retains factory-style mounting points and electrical connections so the unit can be installed as a straightforward replacement without custom fabrication.
Whether the truck is a stock Super Duty that sees lots of cold starts or a tuned 6.7L build with higher cylinder pressure, this Mean Green gear reduction starter offers stronger cranking, quicker spin-up, and improved reliability over a typical replacement starter. For long-term ownership and reduced downtime, it is a compelling upgrade when the original starter becomes weak, fails outright, or is being replaced during a major engine refresh.
