I can't afford to buy the Super Swampers, so I'm still lifting it a foot and it's gunna have 24" AT489s on the back, and 23" AT489s on the front, they were on a Polaris four- wheeler.

Not lifting this one, got a 98 GT 5000 that will be easier to lift, has a sideways clutch. I'm gunna go engine through clutch to a strait axle. I'm still putting the at489's all the way around the other Craftsman.

Still need engine on, bull horns, weld on the hubs, bumper, and lock the 820. The Bull has no front axle on it for the moment, had to wire wheel spindels.

Do it! Don't think it'll be all easy but if you can get it right you will love it Couple things to remember/consider:
Gear ratios really come into play with that big of tires. I say this because I've been toying with a full-suspension variation of this idea for a long time and well, big tires make tons of speed on non-stock gearing. As part of an experiment I put 31x10.5-15 on the back of an LT1000 craftsman and the thing pulled almost 60 with a 5" pulley rear and a 6" front. A great example of this issue :
Now he mentions it'll do 40 or so with an opposed twin. That's with a 10 or 12" rear pulley on the thing and a stock size up front. Needless to say, it'll be really hard to keep the thing upright going that fast, no matter how you engineer it... unless it's REALLY wide.
Wheelies are a distinct possibility as well, but another "oh sh**" scenario.
On the other hand, it'd be a lot of fun and get many looks and questions from all types of people. Me, I say build it
