Hi

I'm just about to replace my Jeep's 231 with a 242J that I got.
The main reason for me is the stronger rear shaft of the 242.
However, I discovered that both transfers have the same rear shaft - at least looks like - which means same splines amount and same diameter.

Can anyone explain if the 242J's output rear shaft is stroner as I was told?

Thanks a lot!

The 242 is very similar, but it has a slightly lower torque rating than the 231. As far as rear output strength, I believe they would be the same, stock to stock. But, there are not any full SYEs for the 242, so a 231 with a SYE will have a stronger rear output.

231 vs 242 rear shaft strength

Thank you turbobrick.
But according to NVG's marking policy, 24x are stroner that 23x series, so is it only about the chain, no difference in rear shafts?

Also, what is the torque rating?

Thanks a lot

According to Novak, the standard 231J is rated at 1600-1900ft/lbs, the 242J 1486ft/lbs. Both can be built up to be stronger, neither is a bad case, it really depends on your application.

There was an HD version of both the NP242 & NP231 that had 32 spline outputs. Maybe that's what you're thinking of?

I would stay away from the 242 - and go 241 .
