Mechman high output alternators · Authorized dealer
With the 4.0L V6 and available four-wheel drive, the B4000 is the Mazda pickup that tends to end up on trails, wearing a light bar, a winch bumper and an air compressor. This Mazda B4000 high output alternator collection lists four Mechman units for 1994-2006 trucks with the 4.0L, rated at 240, 320, 370 and 400 amps.
Trail builds pile up loads fast. A roof light bar and ditch lights, rock lights, an onboard air compressor and a radio all run at once on night rides, and a winch can pull the battery down in seconds during a recovery. A Mazda B4000 high output alternator refills the battery between winch pulls and keeps lights steady while the engine idles over obstacles.
These Mechman high output alternators are a T-mount design listed for the 1994-2006 B4000 with the 4.0L. Choose 240 or 320 amps for lighting and a compressor, 370 amps if you winch regularly, or 400 amps for a dual-battery trail rig. One unit is billet, and finishes include black and natural. Confirm your year and engine in the vehicle finder above the products. The same units are also listed for the 4.0L Mazda Navajo and the Mazda B3000.
A winch-ready truck needs a healthy battery, so see our batteries. Browse every Mazda fitment on the Mazda alternators page.
