Mechman high output alternators · Authorized dealer
A small SUV with a 4.3L V6 makes a great trail rig, right up until the winch, light bar and compressor all want current at once. This page lists every Chevrolet S-10 Blazer high output alternator Mechman offers for the years we carry, 1988 through 2004. Sort by amperage, finish or housing, then enter your exact year and engine in the finder at the top of the page.
S-10 Blazers get lifted, armored and loaded with accessories. A winch is the biggest single draw, and it usually runs with the engine idling and the lights on. That is where a factory-size charging system falls behind and the battery takes the hit. An S-10 Blazer high output alternator keeps voltage up during the pull and helps the battery recover between pulls.
The S-10 Blazer splits by year and engine. The 4.3L V6 is split into two groups, 1988-1995 and 1996-2004, and each takes a different alternator family. Another engine is listed separately, so run your exact engine through the vehicle finder above before you order.
Mechman high output alternators for this truck come in 170, 240, 250, 320, 370 and 400 Amp. Pick an S-10 Blazer high output alternator by what you run most often.
Billet housings are machined from solid aluminum and come in colors like Green, Orange and Black. Standard cast housings keep a stock look. For a dual-battery setup, pair the alternator with a second battery from our AGM batteries and heavy cable from our Big 3 and amp wiring kits. The S-10 pickup page covers the truck side of the family, and our GM alternator collection covers the rest.
