to make 3 Series Gears work for a 2 Series Axle??

 

what type rear?
on a 7.5 or 7.625 10 bolt
3 series gear = 3 series carrier
2series gear= 2 series carrier

The axles are the same...housings are the same, I would never use a ring gear spacer, but i don't think they make it for a 7.5 anyway

 

uh i think is a 7.6 10 bolt is jus a stock rear end on a 97 Z28 with 2.73 gears aka a 2 series rear end

 

if you do need to change gears I would go to a 3series....basiclly the 2 series is a thicker ring gear and wider pinion

the spacing is different to run those hi 3.23 and 2.77 2.73 gears

 

so it is possible if i buy the stock spacers and stuff from a stock 3 series?

 

there is noe spacer, only the parts must match....Why do you ask? doing a gear swap or diff.?

 

i am wanting to do a gear swap i am thinkin of 3.42s or 3.73's im an A4 but im not sure which one is best for it

 

Richmond for sure sells 3-series "ratios" (ie: 3.73's) built for a 2-series carrier. The ring gear is 1/4" thicker than a standard 3-series gear (the mounting face for the ring gear is offset by 1/4" between 2 / 3 series carriers, that's the difference).

You "can" get a spacer and go that route, but it's not highly recommended . Like I say, I know that Richmond, for one, sells two versions of almost all the ratios from 3.42+ .
