4.10\'s or 4.56\'s??? I have a 1985 K5 Blazer. It gets used %50 off-road and %50 on. I live in the north Georgia mountains. I am wondering what would be a better gear ratio for me the 4.10's or the 4.56's. I want it to have more torque. Will the 4.10's give it better gas mileage? Any help on the matter would be most appreciated. Thanks, TB2Blazer.
