what about a np241?

That would be a great setup , and overkill if you didn't wheel it hard . You can get away with gears like that considering the first gear of the 700 and the torque converter :thumb:
 
4.10s with 35s gives you almost the same gearing as 3.7s with 31s. This is what I have and although it's nice to cruise at 80 or 90 at such low revs I'd much rather cruise at 65-70 at the same revs and have the driveability of the 4.65s or maybe even a touch lower!
 
ive got a np241 forsale in the engine/tranny/tcase section. shoot me a pm or email if you are interested.

241 is a great t-case.
 
I'm currently running a 700R4/241 combo, with 35's and 4.56's. Overall very happy, I love the lower gearing of the 241 and 1st in the 700. I think 4.56 is just right for this setup. Might have gone 4.88 if I could do it again, just beacuse I tow a camper trailer and sometimes it struggles when I'm going over the Continental Divide at 10000 feet..
 
yeah, if you have to regear anyway, 4.88s could be an option. how heavy is that trailer u r gonna tow again?

kinda nervous about the tranny swap. noone to help so might just be sticking with the th350/208 combo. i know i can do a direct swap.ill just buy a bad ass built th350 and do a rebuild of the 208. its leaking.still want to run 35x12.5. the 14ff /d44 i was looking at the guy is full of it. so im open to suggestions on this 400 small block/ th350 /208 /35x12.5's. i have 10 bolts now. i dont want 8 lug rims i like the stock chevy with trim rings. what axel combo and gears if i stay with the th350? mild off road play. occasional trailer tow for now
 
the trailer will be towed on highway not interstate. i want to see the country so will take secondary roads max spd limit like 60. we just did 12000 miles on the harley cross country and only hit like 700 miles of interstate and that was the last day and a half haulin a.. to get home!!!!
 
combo

I run a 94 sub with a 383 4L60E and a 241. I run 35's with 4.88's. I'm pretty happy with the gear choice, but I would likely go to a 5.13 than to a 4.56.

sounds like a plan. If you are going to pay someone to rebuild the 208, I'd still consider eliminating the slip yoke on it while you are at it.

still want to run 35x12.5.

if you are going to keep the th350 and run 35s, 4.56 gears would probably be best.

sf14b is still the best option. The 10 bolt rear axle is pretty much the worst axle ever put in a fullsize truck. Especially for towing/offroad use. The newer sf14b axles are 6 lug, will bolt right in and offer quite a bit more strength. If you want the extra bling, you can always add disc brakes to it and some blinging aftermarket shafts. For your use, it'd probably be fine in stock form for the time being.

that would be a 14sf from an 88-? chevy 1/2 ton? does it have to be a 4x4 truck? is regearing the 2 axles to 4.56 expensive? looked into the slip yoke eliminator was told they arnt made for the 208 only the 241 is it worth switching? what type shop regears or is it easy?
 
u can sye a 208, search for dodge 208 sye. you take the back half of a dodge 208 case (they came stock with fixed yoke) and then you have to do a couple welds to the dodge tail housing, you can do it if you can weld aluminum. a couple guys on here run it. its up to you. what is the truck going to be used for?

yes, 88 and up... not sure what models exactly they came on tho. They used sf14b axles before 88, but they were all 8 lug. I would guess lots of late 80s / early 90s burbs have them, not sure what other rigs though. Use the axle ID pics in the tech section to know if you're looking at the right beast.

not as far as I know...

It shouldn't be. Yukon gears are good quality and inexpensive. Try CCOR over in the vendors area, they always give me good prices on Yukon stuff. You'll need install kits with the gears. At any rate, best thing to do is call local mechanics, 4x4 shops etc and get quotes. There are drivetrain-only shops out there too. A good way to do research is to use the region-specific forums here on ck5, and ask if anyone knows of a good/inexpensive place to get a set of axles regeared in your area. Might save you a lot of phone time... and might give you some info on what shops do good (or not good!) work. Sometimes cheapest isn't best.. and just calling shops alone isn't going to tell ya that. Word of mouth is the best way, ya just need to find the right peeps to ask.

If it was me, I'd just lurk in local 4x4 forums and craigslist and pick up a 241. Not sure what spline inputs they use though... I know they did have 32 spline inputs on some of them, which wouldn't work with your th350. You need something that will take a 27-spline input to match your tranny.

they amke 27spline 241's. they use the same adaptor as 208 to mount to a 700r4, so i dont see why they wouldnt use the same thing to mount to a th350

88+ 1500 4x4 will get you the same 6 on 5.5 lug pattern
also an 88+ light duty 2500, in both 2wd and 4wd will get you the same pattern. my DD 93 C2500 is 2wd and 6 lug.
 
I ran 700R4/208 with 35's and 4.56's for several years. If I was going to go that route again I would have gone with 4.88's for a truck that gets driven on the highway alot and 5.13's if it never really saw much of the higher side or 70mph.

I now have 37" tires and REALLY wise I had at least 4.88's.

When I had 32" tires and 4.56's life was gooooood, at least in the gearing department. It cruised with plenty of power on the highway and the RPM's were nice to cruise 65-70 where I like to cruise.
