A couple of weeks ago I totaled my TJ and have since inherited my wife’s XJ. After the wreck I have decided to keep the XJ on the small side and Build a buggy. Now first I know my design is different than most and not the best but I am working on a tight budget and this is a exercise of my fabrication skills. I will be using a front wheel drive motor and transmission mounted sideways in the middle of the frame and run the drive shafts to 2.5 ton rockwells. This will basically give me a 4-low all the time of 6.72 to 1. I am thinking of a quarter elliptical suspension even though I do not yet know much about them. I am going with a wheelbase of 125 inches and going to run Michelin 1600 xl military tires 52 inches tall. This is not multi purpose “street legal” and just the high points of the build.
The question is what other buggies have been built this way? I have looked and have only found one with very little info. What tips do you guys have? Any info would be appreciated.

There was a guy in the middle east that did something like this and this is how the Rhino rigs out of colorado are, minus the rockwells and 52's. From what the Middle East guy was saying the auto's were better than stick, and you may consider welding the diff in the trans to give equal power front and rear. I think the guy called it the frog or something. He used low pinion axles fliped and switched the motor/trans around so it ran backwards and was competing w/ it. The placement of the engine will determine the rotation of the drivetrain in forward gears. maybe look up the Rhino's being built in Colorado and see what you can find out from that. That would be a pretty exotic ride though. Also there is a differential in those transaxles so it would act like a transfer case reduction to what ever that gear ratio is. Any way good luck brotha, post some pics!

Later,
Easy Rick.

I had this very same idea a few years ago before the rhino company started making them, but it sounds like it would work, maybe a little underpowered for the big tires, but not a bad Idea, like what was said above, make sure to take the transaxle apart and weld up the spider gears inside of it, and use the automatic transmission, you will have better luck with it, good luck and post some pics.

You'll be alot lower than 6.72:1, you have the transmission gears, and the differential to account for. First gear x front wheel drive diffrerential x 6.72 = whatever crawl. It would be useless without welding the diff in the transaxle so you actually have 4 wheel drive.

I've been collecting parts for the same idea. 1980 VW diesel motor, 2.5t rockwells (front steer only). I have a lead on a auto trans that may work with the motor as well.

Also thinking about solid mounting the front axle and a rear one link. Either fully solid front or solid with a middle pivot only. Prolly wont work perfect but easy as hell to build.

I'ld question the transaxle strength turning that much beef. Probably be better suited for a 44/9" combo running 36-38" meats.

not if you use a Cadilac northstar motor/trans, but I agree that you would need some power for that combo

Thanks, I have seen the "frog" and the "rinho". Yes I will be welding the spider gears in the automatic transaxle. I am using the engine and transaxle out of a ford escort and after I get it going I am to convert it to propane and turbo charge it. What tips do you have on the quarter elliptical suspension?
Thanks
Marcus
