Hi Chevys,
I have done a engine swap with a Chevy SB plus TH700R4 in my XJ , now I am planing a axle swap with D44 front and D60 rear.
Do you recommand to change the NV231 to a NP241 or not ?The Jeepers can give me no clear answers!
Prost:beer:

I'm swapping a 350/700R4/NP241 in my Scout 800. I chose the 241 over the 208 for a few reasons. Its a little stronger, lower gearing, and its cheaper and easier to convert to a fixed yoke (about $300). I don't know what side your diff. is on. My Scout is a pass. side diff, so I had to get a 241 out of a 89-91 K5 or Suburban, otherwise they're driver's side drop. Hope that helps.

I recommend you go to the 241. Mainly for the front output shaft and the planetaries.

The GM version of the 241 has a flange instead of yokes on the front output shaft . I swapped to a Dodge front shaft that is 32 spline just like the JB conversions short shaft kit. I don't know of a shaft for the 231 that is more robust than the stock one. The main shaft in the JB conversion kit is the same for the 231 and 241.

The other difference is the 231 has 3 planets and the 241 has 6.

The case is a hair taller than the 231 and the front output shaft is a little farther from the centerline.

241 all the way...
Not only are the SYE kits cheaper compared to a heavy duty 231 kit and have a 6-gear planetary (as people already mentioned), but you also get a wider chain, 32-spline front output, and a beefier case.

Just did this swap into my Jeep YJ... I used a 241-C and installed the JB SYE kit.

You can remove and cut the front flange output in two right after the splash guard and use the back part of it as a spacer. (measure VERY carefully) Then you can just bolt on a standard 32-spline yoke just like the one on the rear output. This costs you a little front driveshaft length because the Chevy front output shaft is longer than the dodge, but in my case, it worked out perfectly because I swapped in a longer tranny (NV4500) at the same time. I didn't have to mess with the front driveshaft at all.

HTH,
Jake
