transfercase for running rocks

[84silverado]

what kind of trasnfer case do most of you guys run? would i be able to keep my 205 and run them or should i make a 203/205 doubler or what? im just looking for t-case ideas right now because im about $400 away from calling up wildtime for the first time and going to get a set of rocks. thanks!

205 here

Depends more on what size tire you run if you need to add the second tcase and now much power youbare making too.

What are your plans?

[84silverado]

right now i have a sbc pushing around 420 horse. then a turbo 350 trans and a 205 t-case. and i know also that the tires im getting are 18.4-26. the ones im getting are about half tread, a family friend has them and he's holding them for me until i work/pay them off. i also want to get lockers in both axles before i put them in, i dont want to do it a few months after.

but i also plan on in the future to run a bbc, but my piggy bank will have to have a bit more than it does now lol

I Got A 200, Done Good So Far

the sbc would be great for now the 6.72 will make up for the 57" tires . save some $ and weld the rear . but not the front.

alright cool atleast i wont be losing as much power as i thought i was going to. cause i know my lil mouse motor is gunna have to work over-time pretty much all the time now lol. and yea that is good idea, i think i will save my self a few hundred bucks and just weld the rear   thanks don

i ll do 208 they re light...

Rockwells themselves don't require more power.  In fact the higher gearing in them make it easier to turn the tires.
Its the larger tires that usually come with the Rockwells that require more power or a second tcase.

would i be ok if i ran a 18.4-26 tire on a 2.5 rockwell axle?

[mud for fun]

My s-10 I sold had a 355, 350 turbo/205  2.5s with lockers front and rear ,44 cut boggers. I never broke an axel. Only in clay would I run out of motor/ gear. Im building a new truck with 2.5s, bbc, 18.4x26 r2s, 400 tranny, divorsed t-case 2.6 to1 ratio and im not sure I might need more gear! and unless I upgrade axel shafts (at least the rear) Im going to brake them often. On this one im welding the rear and leaving the front open (it takes a lot of motor to turn all 4 tires). You probably dont have enough drop with A 205 for driveshafts with that much lift. Just my experience.

thats one of the best things about rockwells, angles dont get too crazy with the way the pinion is placed up high.

i run 2.5 rocks, 205 tcase,18.4 26,and a mild built bb . i can turn all 4 . the rear is welded and front is open but all 4 turn. the only problems i have is the rear shafts break sometimes when trying to pull big trucks ,dozer , 2 trucks at a time  or just being stupid. and i do run it in 4low.

[84silverado]

awesome. sounds just like the setup i want, i MIGHT be able to run in more than 4L but only getting it all done will tell so ill find out then   hey DON, this may sounds stupid but have you ever broke any axle shafts with the 18.4-26's?

I m gonna run 350 /400 then divorce t case Dana 24 and running 5 ton Rockwell with 64" tractor for a bit then I ll upgrade 396 bbc with .40 over haven't decide what to do w cam yet and I can't tell u how it ran cuz I haven't ran it before lol but can't wait for its maiden voyage out in the field... Don't worry about  wrong t case I m sure any of it will work just that some maybe weak  and some may be overkill

[84silverado]

yup i figured that i would find out what worked and what didnt when i finally got everything together and going..but ive read the thread for ur boat truck mudduck a few times and i think its awesome everytime 

['the DON']

just a little advise go up to the 1410  ujoint on the drive shafts that helped me alot

[84silverado]

Thank you for reminding me of those I forgot about them lol but I'll upgrade the shafts to them thanks don
