I want to do a swap from my 4 to a 5 just dont know what it is exactly that I need... anything would help as I have no knowledge on this

 

a 5 speed tranny haha

 

lol... ya but what else... just the tranny nd Im good

 

idk ive heard its a direct swap

 

what a bout the t-case? not sure what that is... see it put on CL all the time with our without t-case... should I get a 5 speed with the t-case?

 

Is your truck 4WD? then you dont need a transfer case

 

no its just a 2wd...

 

dude im just wondering what your going to do with that 4 speed when you get this swap done hit me up and let me know whats up with and would you be willing to part with it.....by the way this is a completely bolt up there is npothing you need to chage but the lil shifter knob to 5 speed lol but i mean this in the most nicest way have you got someone helping you do this cause you kinda freaked me out when you said something bout a transfercase being that you got a 2wd

 

hey bro, ima do 4 to 5 speed swap to, depending on when he does it, ill sell u mine... hey ut truck info u can hit 100, i hit 110

 

lmao i havent messed with the diff on mine so i honestly dont know what kinda ring and pinion i got but i know for sure its not the common 4.11 its gotta be a ferris wheel back there this think takes outta the whole like a bat outta hell but after you get to 4th thats bout it i do love these trannys though there are bullet proof and have yet to c any weakness yet call me ol fashion but i wana keep it around for my motor swap but would like a back up im going on the ol fewer **** points better time thing but i gotta laugh 2 weeks after i got it took it over to street fights in bristol and the fastest time i could muster was a 17.5 so after 4 times i went home with my tail tucked and started on my new motor a N/A 7m anyways keep more informed on that

 

haha sounds like a plan but ill let u kno dnt worry

 

i thought some of the 4speeds had a 3.08 with a 8 inch diff in the rear

 

that is correct. most 4 speed manual trucks ive ever seen have had the 8" rear diff and 3:07 gear ratios. they were mainly meant to carry heavier loads and thats why they were beefed up. the gear ratio was meant to bring up the final drive gear ratio because the tranny was so low geared and beefey.

 

in english please alex

 

it's like a 4x4 3rd member but with a different gear ratio. It's a heavy duty rearend in the 4 speed.

 

so i gotta change that too? or its just better if i do?

 

bump... is it a necessary swap?

 

Keep the 8" differential, slap in a 8" Supra LSD.

 

The 5 speed is direct replacement for the 4 speed, the 4 speed isn,t any stronger than the 5 speed to the fact that they share the same main shaft which seems to be the weak link, the 4 speed does have a 8" with 307 gears but cannot interchange any thing with the 4x4 but the spider gear housing because the main carrier housing is offset to hold the 307 pinion, you can put a 4x4 carrier into a 4 speed 8" without issues, the reason they put the 8" in the 4 speeds is because the japs didn't consider work trucks need to travel any long distances, and were mainly city stop and go trucks, thats why there were no sr5 options for 4 speeds, the fastest 1/4 time I pulled with my 4 speed bone stock was 17.3 with the air cleaner lid off.

 

so if i put the 5 speed and leave the 3.07 gears, id b able to travel long distances without problems on the highway and still b able to carry a load?
