Is a 242 T-Case any good? And when adding a lift do u have to have a SYE for that model?

okcjeeper

the 242 has only one advantage full time 4wd that allows you to run 4wd on dry pavement..The 231 from what I have read is generally a little stouter.

SYE need will depend on the jeep..every jeep is different only way to know is add lift if ya get deceleration vibes then you need an SYE or tc drop. If you get vibes only on acceleration then shim the rear and your good to go.

THANKS! Is there anyway to tell what gears u have in ur rear end by the tag on them

OverlandZJ

On the corner of the tag it will have a series of 3 numbers.



3 55 for a ratio of 3:55
3 73 " " 3:73

etc

i'm at 3" of lift with a 242 and no drop or sye. besides the fact that i got through a u-joint at the axle every year its no big deal.

the 242 is actually stronger than the 231.

I agree with that statement to a certain degree. The 231 can not sustain the wear that the 242 can without wearing many internal parts. Thus the 242 will last longer. But for actual strength the 231 has a stouter case and will stand a little more abuse that the 242. So they each have their pros and cons.

Overland is correct in his assessment of rear ratio tags. If the tag is missing you can jack it up and mark the driveshaft and a tire then turn the tire one revolution to approximate the number of turns of the driveshaft to figure your ratio.

The 242 is put behind V8 durangos, the 5.2 ZJ, and some full size chevys and dodges. The casing is exactly the same (except the bolt pattern) on both the 242 and 242HD, the latter is used behind H1s and H2s. You can upgrade your jeep 242 to the 242hd with a few parts.

Thanks 93 that is a nice article which I had never read. I knew that the V8 Durangos had a version of the 242 but did not know about the Hummers.
Thanks for sharing!

I'm at around 6+ inches of lift with a 242. I have a t-case drop, and I do not have any vibes at all from my drivetrain, except the MTs, but that's COOL!!
