NP208 and NP241... strength and other differences?

    Hey all! After finding out that my 89 Burb w/a NP241 (2.72:1 low) has a big ol hole in the side of it... /forums/images/graemlins/frown.gif I am busy looking for another xfer case. The 241 is mated to a TH400, but I already know that you can put the 400-208 (2.61:1 low) on the same adapter as the 400-241.

    I'm really looking for all the differences between these xfer cases. According to POR ( http://www.pirate4x4.com/tech/bible/ ), the 241 was used in anything from 1/2 ton to ONE TON in 88 and up new body style Chevys. The 208 is only listed as an option in 81-88 trucks up to 3/4 ton. If I was thinking straight, that might make me assume that the NP241 is a stronger xfer since the factory thought it strong enough to put it in a 1 ton truck.

    Can anyone help me out here?

    I question that statement the NP208 was only available up to 3/4 ton. The CUCV series, Blazer and One Tons, were outfitted with NP208 (with only a few model exceptions). /forums/images/graemlins/wink.gif

    Oh ya, I don't remember encountering any failures with the NP208, but I've seen acouple with the TH400 /forums/images/graemlins/eek.gif

    If you need a 241 for an 89 let me know. I might be selling my spare. The 208 is an ok t case but I have seen less problems with the 241.

    IIRC, I read on here that the main differences were low range, and that the 241 had a better oiling system....

    If this info helps you in your quest for the propper T/C the 241 was not used in 88 and up 1-Ton trucks. GM switched to a Borg Warner case in these trucks ( either a BW4401 in a K3500 and a BW 4470 in some K3500 Cab Chassis ). The 241 was used in the HD 3/4-Ton trucks w/ the FF rear axle but the K3500's used the BW cases.
    I am not saying that the 241 is weak by no means ( I got a HD241 in my Dodge and it is great ) but I just wanted to help if you were going looking for T/C's in the bone yard's.
    Hope this helps , Tom
