    I know we've been down this one before, but if a guy's gonna run 39.5 swamper boggers, what gear would you guy's think would be best.... Not alot of heavy duty off road use, but enough to make it worth buying the boggers...
    I was thinking 4.56 or possibly 4.88's

    i have 4.88 but would recommend 4.56 side if you want to run the highway or smaller tires ever. if an OD tranny is in your future go 4.88 or deeper

    I'm running 4.56s with 39.5 Swampers in my '77 Suburban. No problems with the semi-built rat 454, but you maybe wanna go with 4.88s if you're running a mouse motor.

    What tranny? How much lift? How much motor? 4.88s are a minimum.
