Collection: Mechman Alternators

Every Mechman alternator we stock, in one place — 170 to 400 amp high output units for Duramax, Cummins and Power Stroke trucks, plus dual alternator kits and the brackets to mount them.

Mechman has been assembling alternators in Knoxville, Tennessee since 1978, and we've worked directly with them for fifteen years on cataloging and product data. Every unit here carries a two-year warranty and bolts in without fabrication on most applications.

Not sure which one fits? Amperage isn't the only spec that matters — pulley, clocking, and case style all have to match, and a 400-amp unit on stock charge wire will fail early regardless. Call (518) 302-1341 and we'll get it right the first time.
