1986 Chevy K10 truck stock rear end gear ratio? I need to know what the stock gear ratio is for a 1986 K10 Chevy truck. Is there a coding system that will let me tell? The truck has a 4-speed manual (stock) and is running 31 X 10.50 tires. I need to find out what rear end it has so I can change to a taller gear for better mileage at highway speeds. Thanks for any help you can offer! |
