208 vs 241

[tom]

Is there any difference between a 208 and a 241? Which one is stronger? Are they interchangeable? I know they are not as stong as a 205, but they have a better gear ratio for rocks.

I believe the 208 and the 241 have the same size chain with the 203 being a little wider. I have the 241 with 170,000 miles and no problems so far and they currently use them on 3/4 and 1 ton trucks. You do have a few more options with the 241, like a 4 to 1 kit (expensive) and a fixed yoke kit. They are probably about the same as strength but don't know mutch about the 208.

I think they are the same. Except the 208 has a 2.61:1 low range and the 241 has a 2.72:1 low range.

The 241 is basically a reworked 208, both are aluminum housing and chain drive. The biggest difference between the two is that the 241 is supposed to have an improved lubricating system. That is supposed to be the main reason for failures in the NP208, lack of lubrication. Strengthwise, I'd guess they're about equal. I haven't come across a torque spec yet but I say they're certainly up to the torque of most smallblocks.

My brother's 1 ton 4X4 dually Dodge with the V-10 has an NP241 transfer case. That truck has a Dana 80 rear end, I think. Not that the Dodge V-10 is that much of a torque monster, but that t-case is pretty good overkill for 1/2 ton small block powered trucks.

The 241 in my '90 Sub has been through 4 700R4 trannys, and 2 350 engines, while the 241 is original with 250,000 miles!!!

Great input; Thanks. Sounds like the 241 is no problem in my small block blazer. Is the fixed yoke kit a good investment? What does it do besides improve drive angles. Hey, here is another thing. The 421 case hangs fairly low. The crossmember is hung down on 1 inch spacers which I am told the factory put in. Can I just remove the spacers to get a little more breakover clearance? Maybe with a yoke kit, the drive angles wouldn't change much. The truck only has about 2 inches of lift.

I have a problem with my `89 K5. The NP241 makes noise, when i`m driving in 4wd it`s sounds like a bearing is damage in the transfer case. The car is driven for a long time whit hub locks on.
Does anybody know where i can buy a rebuild kit for the NP241?

4 Wheel Parts had one last time I was there. I forgot how much it costs though, somewhere around 190-210 bucks. Anybody know the difference between the NP231 and the NP241?

NP231 are used in Jeeps, I think they are a tad lighter duty, but I could be wrong.
