How difficult is it to swap out gears in the 7.5 housings.
I have a t-lok and gears in the garage waiting for install.
I have built up a few 9 inch chunks but those are simple.

 

Best left up to a professional, honestly.

 

ive never put in a t lock but i did my gears myself. its just tedious, as you probably know

 

i heard that it's real easy to mess them up

 

if you have never done them before it is real easy to mess something up, better off shopping around for prices from reputable shops

 

I don't know why everyone is so afraid of gears. It's not a bad install. It's not hard by any means, it's just time consuming and tedious. If you're good with hand tools and following directions, then give it a shot. I've done a bunch of them, and it's really not that bad.

 

cause most people dont have the time/patience to have their car out of commision if its taking them too long, right now my rear end is out of the sixxer to replace my broken t-lock but i have the luxury of another car

 

Would i be better off swapping in a 9 inch with a 3.60 4.74 or 6.00 gear with a detroit locker or building up the 7.5 with t-lok and 3.73 gears. I have all the gears, but would have to build the rear housing for the 9 inch.

 

Well if you have big plans, which i think you may by looking at your sig, for the car an 8.8 or a 9" would be a good investment.
