i think i have 323s bc my 1st gear goes up to damn near 55mph. i didnt realize there was all that other stuff involved. anyone kno where to get the entire kit?

 

I guess im going to start saving up 700 bucks and get it done.. i would like 410s but i drive 60 miles hw a day average, sometimes more. so i think 373s would be better. the thing is i do not have the money to buy a new tranny anytime soon. so for now its going to be true duals then gears.. unless u guys have any other ideas.. i would appricate it.

 

i get the same mileage with my 3.73s as i did my 4.10's...not much difference in rpms goin down the highway. get 4.10s

edit...i drive 60miles a day as well

 

and how much did it cost u? for everything.. also where did u buy it at

 

my gears plus install was 550...thats motive gear 4.10s, install kit, and labor. i also put a detroit tru-trac in there while i was at it. don't you think that would suck to spend that much money for gear and install just to have your piece of **** g-80 take it out...plan on spending another 400+ for a good LSD

 

so im looking at 1grand for a whole rear end. locker and gears plus install.. wow. i hope that the tranny will hold up..bc that would be another 1800 or so for a flt. im guessing this isnt the best time in my life to be modding my truck since i am trying to save to move and go to school for hvac. so for now ill do cosmetics(no rims) sound system. maybe suspension?

as for performance i can do pulley, pp tb, headers.. and i cant think of anything else at the moment. what else is there? thanks.(somewhat affordable)

 

Go on Ebay and buy a used set of GM gears. It will be cheaper, easier to set up and you won't have to break them in.

 

will it put stress on the g80?

 

?????????????????????

 

sorry dumb question.. so im looking for 410s on ebay.. and i dont need a kit to make everything work like motive and other companys.. bc its factory right? everything is already there and all it needs is to be installed correct?
