Question stock sami, 6.72:1 axles and 44" tires? will it spin?

Would I have troulble with a samurai with a 1.3L motor, stock trans and t-case, 6.72:1 gears in the axles and 44" cut groundhawg tires?

Do you all think it'll be able to spin or turn the tires offroad (FL mudding)?

I have everything already and want to consolidate my junk without buying anything extra.

Maybe with double cases. Really all you can do is put it together and try it. But i would add another t-case in there if it was me.


And yes you can mount them back to back if needed.

Yeah, when it's floating in the water on the 44"s.

I think you are gonna want alot more power with that setup.

Maybe take a paddle too, for when you're floating rubberside up to flip it back over like a kayak!
Good luck, sounds like a fun build.

oh, and pics, pics, pics!

I dont have a bigger motor laying around just a sami, 2.5tons and 44's, so this is a way to get rid of some junk by putting it together

Open front and rear??? Cause if you locked up you are going to break some shafts.

A 1.3L is going to break 2.5 axle shafts? I know they are kinda crappy in stock form but I think he will be ok.
(or did I miss your sarcasm?)

It will not be enough gear. Not in thick mud anyway. I'm not that familiar with sami's but you can do a 4:1 re-gear of the tcase right? Try that before you start putting a profab or something in there.

You can go 6.5-1 in the t-case too. I read a few weeks ago that someone just came out with new 8.1 gears for the t-case. I think it was Trail Tough but I'm not sure. I'll see if I can find it.

I met a kid last year at the 4x4 demo for the Sportsman Expo and he had a Zuci running on Rockwells and 44s with the stock motor and it did just fine. I don't remember if he was running twin Tcases or the Tcase Ruduction kit, but it crawled great. There's no way to really make it dual purpose anymore as far as streetability goes, so just lock up the axles and add the Tcase kit and you should do fine.

i don't know shit about sami's but the same goes for any 4x4. you can't just do one thing and hope that everything else will hold. ex. 2.5 rockwells with stock trans t-case and motor. save up some coin sell the stock drivetrain to the sami guys get a 350 sm420,465 t-350, or t-400 and a t-case of your choice. for mud there's only two things that matter horsepower and ground clearance. you will have the ground clearance now get the hp. you can build a 350 with 2x the hp for the same price as a turbo'd 1.3. if you were telling us you wanted a rig for crawling i would say do a doubler and your fine. as mentioned above just because you got some shit and you are capable doesn't mean you should.
