for 8237-270 for 2004 blazer
exceptional performance low +high rpms . will hold 14.7v with all equip. on. even with pcm controlled idle rpm's of 550 rpm. appearance very nice. cannot verify max output when cold of 270 amps but it seems to drop only a little when hot and alt. still maintains output very well.a bit of a hassle to find the correct belt size but did find the best size. spencer
