    Does anyone know how to get your final drive ratio?
    I am curious because I have talked to a few people that were able to tell me what my crawl ratio would be with certain components ie. 350/465/205/4.56 = ?

    Do you simply multiply their ratio's together or is there a proper way to do it.

    Yes just multiply the gear ratios for your transmission, transfer case, and your ring and pinion.

    .....That's fine for calculating "Crawl Ratio", BUT if you plan on taking this thing to the local malls, you also need to calculate your "Mall Ratio"


    Mall Ratio = Tire Size x 1/Bolts in Axle x Number of Extra offroad lights x Number of steering stabilizers on front axle.

    It is interesting to see that 10-Bolts and 44's will net you a higher score, than 1-Ton axles would....! /forums/images/graemlins/cool.gif

    you have to include tire roll out to get a useful comparison number

    So you're telling me that my monster 29-8.50's really affect my 3000:1 crawl ratio ? /forums/images/graemlins/wink.gif

    Same kind of thing is true of RTI socres, track width affects it yet no one considers that.

    rti scores are a useless/meaningless stat that can be easily skewed
    gear ratios and comparing them is a useful tool to tune your ride
    in both cases bigger isnt always better
