What's up guys

I've been running across a lot of 4cyl 5speeds with 8.25s but I want to know what years would fit my comanche...I've seen 4 pre97 Cherokees and 2 97+ Cherokees with them....

What years best fits my comanche

 

4cyl 5speed 2.5 with 4.10 gears....

They are all the same width but none will bolt in. The spring pads and shock mounts are different. For one thing XJ's are SOA & MJ's are SUA. You can easily adapt one if you can weld. Look for a'97-newer to get the stronger 29 spline version

Going from 27 to 29 spline is as easy as swapping spider gears and shafts ... so don't limit yourself. The switch to 29 spline occured in 96 so they'll be a mixer year. In any event a 8.25 is loads better than a D35. I also like that they used equal length shafts so only one spare for both sides.

Ok I know about the spring pads...

But the difference from 27spline to 29spline is just the axle shafts and spider gears?

Nothing to do with the transfer case or anything correct?

The side gears in a 29 spline carrier are physically larger than the 27 spline version. The axle shafts are larger. I think that you will find that the carriers need to be swapped as well.

Well, how about you send one of them up here to E TN? Nothin' round here.

This is actually the first time I've seen so many...

And they are all 2wd Though..I would love some of these gears for my cherokee with 3.55 but it'll take longer to find front gears than rear

Make it SOA and you probably won't need to shorten the drive shaft.

That's a simple solution to a complex problem. Or do I have that backwards? 

 

Who knows? Ever since the "event" things just ain't the same.

Since he's welding on spring pads anyways, how much extra work is it? (I know. I know. He has to lift the front to match)

You can buy a 4.5" kit for less then a good SOA if you do it right and it is complete. Granted some of the 4.5" kits aren't ver complete either.

The nose of an 8.25" is an inch longer than a D35. If your yoke has at least 1" of rust that has never been inside the transfer case your rear driveshaft will work.

 

The 29 spline ones are stronger than the 27 spline ones. The changeover was some time during the 1996 model year.

I just offered another option that "shouldn't" cost more. I did that myself putting an XJ axle in mine. I even run OEM shocks but the mounts I made weren't as elegant as I have found since. I also replaced my springs at the same time with Metric Tonne ones and converted to 4x4 so I could clear 33/9.50/15 tires. I even run stock ebrake cables. I just moved the floor brackets slightly.

   You have to add shock mounts when you do an 8.25 swap as well. I have swaybar plates from an early Jtruck (you can probably use CJ aftermarket ones. Test fit them to the shock lower bushing) which are flat plate with a mount stud. You will need a longer spring centering bolt to pass through the plate and into the axle's centering hole.

   I'm not one to re-use spring U-bolts, but the 8.25 is a wider tube and the spring plate off the D35 won't fit either.

Ok to bring this thread back to life...

I wanted to ask if I were to buy a 27spline 8.25 with 4.10 gears and if I grab some axle shafts from a 29spline (I do plan on buying a locker) is there any differences?

Sorry if I sound newbie I'm just trying to set myself up the right way...thanks in advance

Depends on the locker, if you get a full case 29 spline locker you should only need the shafts. If you go with a lunch box locker you will need a carrier for a 29 spline axle.

Yeah but I don't have a full size truck or trailer to bring it down to miami...

 

Edit: oops sorry I didn't read what you wrote...yes I saw a few that I know had the 27spline when I went back to the jy I saw 2 29spline ones but one was already taken and I know the other one by now should be gone to....

Ok yeah I was planning to buy the lunchbox from lokka...so I'll have to be on a look out for a full case 29spline 8.25
