38 Super Swampers on a 1972 CJ5

What would I have to do to put 38 super swampers on my 1972 CJ5 .... I measured and it looks like it will fit fine level but may rub when in a bind ... I just plan to use it in mud, and not rock crawling.


I was told the springs have been flipped and a google search does show they have .... my springs are flat ... if I get some new ones with a bow will I be OK, or will it throw the driveshaft in a bind?
THANKS FOR ANY HELP ..... OH, and I don't mind a little rub now and again .... it it don't rub, it ain't big enough.


Here is my front springs!

What axles do you have? the factory 30 and 44 are not going to hold up to 38's. I would routinely break axle shaft ujoints on a 44 front with 38's. Does your rear driveshaft have a double-cardan joint at the t-case? if not, then yes you will probably bind the driveshafts with more lift, but we will need pictures of your current setup to give better advice.

HAHAHA!!!! ..... Now I finally found a topic on it ... looks like I am not the first fool ... a friend has 4 nice 38x12.50-15 TSL Super Swampers he doesn't want or need, I can get them cheap ...... would I be better off putting 35" regular mudders on it .... here in East Texas the mud goes clear to China, and I don't want to get stuck, and will not be getting real rough with it, because I am old, broke and tender!


I found this topic

That is my server on godaddy .... they are fixing to get canned for that crap .... I know what you are seeing, but not everybody sees that warning ... it is safe!
It used to not do that ... then they moved me to a cheaper shared server and jacked the price up ... ANYWAY, I have decided to not go that big, I am going to go with 35" or 36" tires, because I know they will fit as is.


I do wish somebody would look at the diff pics and tell me what I have!


What is this?
Rear Diff




Front Diff






THANKS!!!!

When you reply, click on the paperclip and then upload your pictures. The only way that I can see them is to open in a new tab of the bad image on my phone. Can't see them from my pc.

The diffs look to be the stock Dana 30 front and Dana 44 rear for 72. 1st year for the centered 44 rear and 30 front on a CJ

Diff cover guide. Dana 30 matches what you have.

WOW .... THANKS ... I am saving this!
Found me some nice looking 35 aggressive mudders and will go with that ... It had 36 mudders, but a 70 yo mad drove it ... well, I guess he was closer to my age when he got it ... but was in his late 70's when he parked it.


TWO PROBLEMS SOLVED!!!!


Here is what I plan to put on it ... this is 20" rim, and they make one for 15" rim that I will use!

OK, you have a Dana 30 / Dana 44 and it is SOA (Spring Over Axle) so you will have enough clearance for the 35" or 36" tyres, no problem.

You have a 304 V8 so enough power but how about rear driveshaft angles? The CJ5 is awfully short for SOA and this is where a common problem occurs.

Been like that since the 80's with 36" tires ( they are so old they say Q78-15 on them) .... But Two old men drove it .... my dad and his best friend .... I am 62 now, and I don't plan on racing .... just want to go through deep East Texas mud!
The rear axle is at an angle and only about a foot long .... I will probably break something .... then have to fix, then that will probably break something else ... then on and on.
This is my first Jeep, but not the first thing I broke! (I used to like Big Block Chevy and have about 20 of them ... I have broke everything that can get broke!)



I am glad I got talked out of the 38's ..... why do you spell tires "tyres" are you from England? .... I have a friend from England and that is how he spells it!
