250 Amp HD Series Alternator for 6.0L


We stock alternators for Ford trucks, but have access to numerous other alternator options for the various makes and models out there.  If you have a specialty need, please  Contact Us

DC Power set out to source the most dependable and affordable 250-amp unit for the Ford Powerstroke 6.0L using the best OEM Heavy Duty components in the industry. DC Power’s 250 Amp HD series high output alternator is the result of utilizing brand new OEM Delco Remy Heavy Duty components. DC Power accomplished this incredible feat by having the capability to design the custom billet drive end frame to create a direct drop-in replacement. DC Power is able to use a larger 3605 NTN bearing instead of the traditional 6303 NTN bearing found in the Motorcraft 6G unit which allows for better heat dissipation and increased durability under the most extreme conditions. Comparing the 250-amp HD series alternator to DC Power's highly popular 185-amp OEM series, the 250-amp HD series will provide a 35% increase at idle output and a total average of 30% increase in output over the entire output curve.  DC Power sources all OEM parts directly and stand behind all of our products with a 2-year warranty. If for any reason your alternator ever needs service, DC Power offers free lifetime labor on all units; simply pay for the parts and they will take care of it. DC Power is so confident that you will be satisfied with the new 250 Amp HD alternator over any Ford 6G alternator that they will back every purchase with a 15 day return policy with no restocking fees.

Note:  The HD series of alternator is about 1" deeper than the stock unit.  This will result in a snug, but very possible fit in 6.0L applications using the stock CAC tube.  If you are running a Banks or other aftermarket CAC tube application, this alternator will not fit in your application.  If you are running with aftermarket CAC boots, modification of the boots may be necessary to achieve proper fit.  Please consider either upgrading to the 270XP or 370XP series units or downgrading to the 185 amp OEM series unit.
