    Will the sm465 mount up to the np241 in my blazer? If not is there kits out there to make it work? What are the down falls of the np241? I see that everyone with the sm465 runs the np 205 and figured that its for a reason.Still learning alot about this truck everyday, I know more about newer trucks but I love to research anything and everything I can get my hands on. Thanks guys.

    People use the 465/205 combo because they are extremely strong and came from the factory in this configuration in a #$%@ load of truck so they are easy to come by. 241 is chain driven as opposed to the gear driven 205, so it is not as strong. The 241 will have a better low range gear ratio than the 205 though.

    You can get a 465 that will bolt to a 241. You need the 32 spline version of the 465 that was available in front of 208's and 241's along with the adapter.

    The 241 must be a 32 spline input 241 too. A 241 from a 700R4 trans must be converted from 27 spline to 32 spline.

    205 = super strong, crappy low range, heavy
    241 = light, good low range, weak aluminum case

    241's are similar to 208's as far as the case and slip yoke are concerned. They don't take the "bump" very well. I remember a late night towing somebody's TPI blazer home with my 7 cylinder'd q-jet for proof /forums/images/graemlins/whistling.gif /forums/images/graemlins/grin.gif. As long as you have some reserve the aluminum t-cases are a great option.

    you need a stock adaptor and 32 spline 465 like some have mentioned. I have a two 465 to 241 combos. Both in use, sorry. My burb has came factory with the combo, and my trail rig has a 465 that originally had a 208 behind it but now a driver side drop 241.
