Jman062006 I found a 241 case from a 96 tahoe what would bolt right up correct? The guy was saying that 94 to 96 will be the same.

punkafi888 you can also controle the front and rear axles sepratly. easy to adapt to anything and you can pick them up at most junk yards. down side. it is passenger side drop, so you have to get a flip kit, up side to that is that it flips and adds dual sticks. check out novak conversions best site with the best info i have found.

Jman062006 I thought the 300 was lower geared than the 241. It seem to be the most sensible case for me at this point.
08-03-2009 03:17 AM
punkafi888 personally i would not do any thing lower than a dana 300 with some tera gears.

Jman062006 As far as sye kits go, does anyone run the high angle drive line kits? I was wondering which kit was the strongest for the 241? The only other option I have found it the jb conversion kits. You can also get a drive line brake kit from high angle which I havent found else where but not sure if i need that

Jman062006 I guess the main question I have is are all of the np 241's 27 spline? And if not which years of trucks were?
07-29-2009 08:53 PM
Jman062006 bump
07-24-2009 07:20 PM
Jman062006 anyone know which trucks would apply?
07-19-2009 10:14 PM
Jman062006 now I am just trying to track down a 241 transfer case. I think I need one out of a chevy 1500 but im not sure.
07-19-2009 10:05 PM
jpdocdave very nice
07-19-2009 09:49 PM
Jman062006 I already bought the 8.8 out of a 97. Disc brakes and 4.10 gears to match the d30. pretty sweet
07-19-2009 09:13 PM
jpdocdave did you get the 8.8 years figured out? the disc brake axles were on around 95 and up, 96 for sure. the earlier ones are still pretty strong, just with drum brakes. as long as they have the 30 or 31 splines they are strong, disc brakes are just a bonus. the drum brake 8,8's are very affordable.

what years and models did those cases come in? My local junk yards cant look it up by case it has to be by vehicle. (drivers side drop)
06-19-2009 07:44 PM
Jman062006 Which year explorer is best to get an 8.8 out of? Does it have disc brakes?
06-18-2009 05:32 PM
1BLKJP I think at 208 is going to be stronger than the 241. It's an iron case and gear driven instead of aluminum case and chain driven.
06-17-2009 10:15 PM
Jman062006 well I was just reading that the 208 is the same spline count which one is stronger?
06-17-2009 10:12 PM
Jman062006 So with what Im reading it looks like the only bolt up case with 27 splines to match the tranny is the np 241 so I guess Ill go that route if you all think it will hold up?
06-17-2009 08:20 PM
jpdocdave has lots of great info on what bolts to what, or what needs a special adapter.
06-17-2009 07:39 PM
Jman062006 would the np205 and 241 bolt right up to a 700r4? I just found a good deal on a 205 just rebuilt and ive herd they are one the best cases?
06-16-2009 06:31 PM
1BLKJP An NP207 isn't a bad TCase. jeep used them before they went to the 231. I think they stopped using it in 1987.

If you are going to mount that case to a 700R4 you are going to have to get an adapter setup to do so. The spline counts don't match between the two. The adapter includes a new output staft on the tranny itself.

Oh, and if you have a v8 you don't even remotely need 4.88's to cruise on the highway with 35's. You'd be fine with 4.10's or even 3.73's.

Jman062006 anyone?
06-14-2009 09:51 PM
Jman062006 the trans and t case i can get are out of an 87 jimmy and i was reading i think it comes with a np 207 are they any good?
06-14-2009 09:48 PM
Jman062006 Kool man I really appreciate the help I will look into that kit. Which gears do most use when in my situation a lot of highway and a little offroading? 4.88s?
06-14-2009 08:49 PM
jpdocdave not sure on which 700 trans, but the 8.8 will have the same bolt pattern as the d30 front, thats why i suggest just doing that. they make a super 30 kit or something like that, thats all i'd say you really need.
06-14-2009 08:35 PM
Jman062006 Isn't there a year (I believe it is 89) when they made the valve bodies a lot stronger in the 700? From what I hear is was more dependable just curious if anyone else has herd this?
06-14-2009 08:08 PM
Jman062006 700r4 for the trans and the one I can buy comes with a 241 i believe. Would the 8.8 have the same bolt pattern? What should I do to beef up the d30?
06-14-2009 07:11 PM
jpdocdave with that info i'd suggest going 8.8 in back, and beefing up the front d30. doesn't sound like you need to go crazy, and i can't remember what trans you said, but i'd just use a gm 241 if it bolts up to your trans, they are not bad cases. otherwise adapters for other cases run 600 bux easily.
06-14-2009 04:33 PM
Jman062006 I think I will be running about 33" or 35" tires. It will be doing alot of highway driving and moderate offroading nothing too extreme. Is there any newer vehicles that had both d44's that might be easier to find at a junk yard?
06-14-2009 10:22 AM
jpdocdave tough question with many variables, its best to figure it all out now. so you can buy a t case with the output on the same side as the axles you buy. i bought d44's front and rear out of a 79 scout, the front axle requires a little work to change the pinion and caster to do it right, not a diy job. the rear is super simple. but this way my front axle is the right side drop and both my axles match the bolt patterns.

i'd suggest finding them out of the same vehicle, bolt patterns will match right up. figure out what wheeling you wanna do, and what size tires you want. a d60 isn't really needed untill you go over 36 or 38" tires in my opinion. gm trucks are easy to find a d44 front, and a 14 bolt rear (which is bomb proof) but its gigantic, and you lose ground clearance for it. 8,8 is a good rear axle, but nothing that beefy is gonna match the bolt pattern other than the stock front d30, which you could just build up a little.

there's even more variables, decide what wheeling and tires you wanna run, then that will be how you determine what axles you want.
06-14-2009 09:36 AM
Jman062006 It sounds like the 205 is the way to go with me. Which vehicles did they come on? I was thinking of eventually going to a d44 up front and a ford 8.8 of dana 60 in the rear. Which drop is the 44? and what vehicles had those? Thanks for all input
