8.25 with 2.71 ratio?

[Blackbird73]

Is it possible to change the carrier to the larger version? I want to go from 2.71 gears to something above 2.76.

I read on a Hemmings article that any diffs with 2.71 gears have a smaller carrier. Has anyone ever swapped in a larger carrier? Or do I need an entire new housing? Hope I can just get a suregrip carrier and a ring and pinion and pop it in and throw the small carrier in the bin.....

I read the article wrong its 2.71 and up that is the larger carrier... I will just get a sure grip and ring and pinion later.

If your ever going to put some power in the car you should replace the 8 1/4 with a 8 3/4. Money well spent!

I would also get deeper gears as well. What kind of build are you running....?

There is a 3.21 gear set available for the 8.25.

I would suggest also an 8 3/4 swap the 8 1/4 are good drivers but put anything over 300 hp to it and good by .I had a mostly stock 318 in a car along time back and learned the wonders of a thing called power braking,:grin: so first went the poor 904 then I rebuilt it and didn't learn my lesson figured hell it's a new trans maybe I can go till I dismount the tire . .... Well the rear didn't hold up that good that time about 3 mins into this burn out it let loose . So I then found a nice 8 3/4 out of a car (didn't do anything to it) just a bolt in and add new oil tryed to boil off the tires agen and I was very successful this time took them clean of the rims . That rear stayed in that car and took anything I could throw at it and never came back out even after the 440 and 727 swap took place I still couldn't kill that rear end when I sold that car I switch the rear out for another 8 3/4 I had built (figured I would of killed it already ) and I still have that rear hanging in the rafters figured it was tough enough to handle me as a teenager it deserved to be retired and rebuilt for a well taken care of car build like one that may burn the tires once a year kind of car. You know the pampered ones .
Good luck ether way but a 8 3/4 is a great upgrade and money well spent it won't be the weakest link anymore !
