    i've noticed (through lots of reading of old threads) that alot of guys are switching from the 208 and going with the 241 transfer case

    why exactly? the 241 is computer controlled, isnt it?:confused:

    i got a 86 k-10 with the 700r4/208 combo, and have been thinking about finding a 241

    any thoughts?

    241 has slightly higher low range. its internals are stronger, and there is an off the shelf sye kit for it.

    '89 241 was only year of mechanical speedo. '90- were electric

    so...if, and i mean "if":( i found a 89 np241 it would bolt right up, mechanical speedo and all to my 700r4, right?:confused: ...i'm thinking i read that both are 27 spline, right?

    then i could just buy a sye and be set

    Ok, here's a couple of questions; do the 32 spline and 27 spline inputs interchange? Are the guts the same between driver and passenger drop-- just different housings?
    Thanks, Jimbo

    you can use a '90- np241 and then just swap the speedo housing. would be perfect time to also do sye if u went that route

    The 32 and 27 splines do interchange, they use the same bearing and seal. Ive done this personally and have pictures of the measurements if you would like proof.

    P-drop and D-drop have different gear tooth profiles form what Ive heard as the newer ones where cut differently to be quieter. The interchanging results in damage from another source.

    If your 208 is in ok shape and you don't have need or are planning to go SYE in the near future spending money on a 241 just to replace a good 208 is a waste of money. The 241's lowrange and strength advantages are not significant enough to warrant the swap unless there is a motive behind it like a junked 208 or the need for a SYE ASAP.

    If you do decide to go the 241 route, make sure you also get the plate that bolts to the shift rod on the transfer case side. The one from the 208 is shaped slightly different.
