Is a NP241 that bad?

    actually the 241 seems to be catching on, mainly because of its 2.72 low range but it is a pretty strong t-case, i forgot where i was but i read a guy saying he was going to take out his 205 and replace it with a 241 for wieght savings, with a SYE and mayby a clocking ring in the future i think its pretty good

    There's not too much wrong with a 241. It's just a glorified 208, but IMHO, the 208 is better. Given, the 241 has a 2.72:1 low range compared to the 208's 2.62:1, but I'd still take the 208. The only difference is a modified oiling system, and the option of mechanical or electronic speedometer. That's pretty much all you have to look out for. Rebuilding it is easy, and the kits are fairly cheap, but they make you buy the chain separate. Both the 208 and the 241 can be converted to fixed yoke, so it's all a matter of opinion. Just be sure to run a good skidplate because aluminum doesn't like rocks.

    The 241 is a pretty good t case. All they really need to do now is come up with a 4to1 low kit for them. /forums/images/graemlins/tongue.gif

    They actually do have that, but in our trucks they would break too easily. Something about the planetaries in it are so small after the 4:1's are in.

    Just wondering why you think the 208 is better than the 241? As you pointed out better oiling & lower low range. Add in a more robust case (that sill needs a skid plate) than the 208 and it looks like the 241 the winner hands down.

    The 241 is better than the 208. The 208 had problems with the rear case half cracking due to age and load. There is no 4:1 low range for the 241 yet there is one for its little sister the jeep 231 though. A SYE (slip yoke eliminator) is a must. All in all a good general t case.

    would the swap be any harder than a 465/205 swap? this is off of a 89 K5.

    The 241OR has a totally different set of planetary's than the regular 241's . They are much larger to handle the steep reduction ratio. The case is different to accept the larger gear set too .
    From what I have seen the 241's are a fairly good case - it is no 205 but for what it is they are moderately strong. It would be nice if the parts from a H.D.241 out of a later model H.D. Dodge would fit a regular 241 - they have thicker chains/sprokets an extra bearing on the main shaft and a MUCH larger rear output shaft along with a better type of case material .Just as a note - not all H.D. 241's are created equal - there were several revisions as the years went by.

    would a 465/241 combo bolts up as easily as a 465/205 combo?

    Yes and no. Once you ahve all the right parts it would bolt up as easy. You would need an adapter for the 465 to go to a 241, not sure if GM ever used that combo and if not you'd have to check with Advance Adapters or Novaks.... Although the 208 adapter may work.. Once you had the adapters and the driveshafts the right length it should be an easy bolt up.
    With the 465/205 combo you can basically use "factory Gm" parts t bolt the combo up...

    I have beat my 208's for quite a few years without problems. What type of wheelin do you do or is your K5 more of a DD? You should be fine with a 465/208 or 465/205...

    I've said that and I will most likely do it maybe this winter. I stopped running deep mud so it looked like a cheaper way to get a lower low range.

    ok, this combo is already bolted together. is there anything else that would be hard?

    and SM465 came in 87-91 with NP241 tcase. ANYWAY it's already bolted up, would anything else be harder than a 465/205 swap?

    Well the only other areas you would need to worry about are crossmember placment(if your vehicle wasn't equipped with this) and driveshaft lengths/u-joints..... You may need ot drill new holes for the crossmember mounting and you may need to lengthen or shorten your driveshafts. Also, your u-joint sizes may not match up...
    One last thing, is the 241 a mechanical or elec. speedo hook-up?

    The first year for the 241 was 89. Nobody makes a 4to1 kit for the GM case yet. I have spoke with a few vendors about this and from what I have been told it is in devolpment but nothing concrete.
