Default CJ axle choices

this will be down the road but figured i'd be asking now.

seen on the good ol' wikipedia that CJ7's had rear dana 44's for mid 86 and 87 so safe to assume i wont find one.

the end project is 35's, nothing bigger but nothing less either. right now it has a 4 cyl iron duke, not sure if i will upgrade to a 304 or not =/ im guessing 4.56 or 4.88 gears. THIS WILL BE A ROAD DRIVEN VEHICLE.

my questions are which gears i should run for this and what axle types? i was guessing dana 44's front and rear.

thanks in advance,
doug.

The 1986 WT D44s are not as hard to find as you may think. You can get one and pair it with a narrowed 76-79 Wagoneer D44 front (converted to 5x5.5").

Or, pair the aforementioned 76-79 Wagoneer front with a 1986-up Grand Wagoneer D44 rear and leave them 6x5.5". They are a nice width at about 61" WMS.

You are right on track with your gear ratio selection. Go for 4.88s with the smaller motor.


Shameless plug: I have both a complete 4-bbl 304 and a 360 shortblock sitting around right now if you are interested.

now with me having the narrow track all that really has to do with anything is just that my axles are narrower, nothing to do with the body or frame right? also was thinking about when i do my armor that gen right has the 4" or 6" fender flares so i could run a wider axle if needed. thoughts?

These axles won't stick out enough to require fender flares like that.

You are correct about the axle width. The difference is from the perch out. No differences in the body or frame.

4" flares are going to increase your width by 8" and tire coverage isn't even a requirement in Michigan.

YJ/XJ/TJ axles are ~60" WMS. Wagoneer fronts are about 0.5" wider per side. The vehicle will look like it has good proportions with a lift as long as you don't drink the tire shop kool aid and let them sell you wheels with low backspacing.

thanks good to know. im probably just gonna do a SOA w/ YJ springs but trying to make everything look proportioned. and i just like the look of the flares covering the tires. looks mean to me and not like a mexican jeep.

You could also run the waggy front with the Isuzu d44 rear and already have disc brakes

Just a fyi. If you do choose to go with the waggy front end here are some things I ran into on mine. It is alot cheaper and less time consuming to just out board your springs. Keep all the steering parts as they are way more beefy then any cj or yj. I had to try several different pitman arms to get the right drop and length so it didnt hit the tie rod. You might want to get on craigslist b/c there is a guy selling scout dana 44s and they come out of a jeep. Same lug pattern too. I think he wants 450 for the set.
