Okay, I need the original GM part number for the 3.73 to 1 ring and pinion gear set that fits our 10 bolt STOCK rears. Since my '97 6 speed came with stock 3.42:1 gears, my local GM dealer can only find the P/N for that gear set. Does anyone out there have the GM OEM part numbers for the 3.73:1 ratio ring and pinion set for our cars???

TIA for all replys

 

Okay, SOMEBODY must be running around with GM 3.73 gears in their car, right???? Who knows this part number? TIA

 

All that I know is that the GM gears are $80-$100 more than Richmond...etc

 

Yup, but I got a "connection" up here in Detroit that can get me the GM gears at cost Just need to tell him the GM Part Number, and he can order them for me

 

sweet...more power to ya...

 

GM gears are still ~$500 even at wholesale prices. Way more than any aftermarket gear. Even if your "cost" price is lower, it's not going to be as low as aftermaket, I bet.

You will have to find the part number for someone with an S-10 or something. They did not put 3.73s in the F body, so there is no part number in the book. No one I know buys the gears from GM. Too much $$. The Motives are said to be as close to OEM as you can get.

 

Shoebox, once again your are "The Man". That may be the critical piece of info I need to solve this puzzle It is the S-10 trucks then that use the 3.73:1 rear axle ratio gearset that also fits our 10 bolt F-Body rear ends??? If this true, then I can always ask at the dealership for them to look up the S-10 ring & pinion P/N

 

If you are in MI, call Drive Train Specialists. I am pretty sure they can answer your question and probably give you a good deal on the gears.JMHO

 

First off, Bubba thanks for the tip on DTS Yep, I am up here in MI and I know they do pretty good install work.

Now, I just got off the phone with my local Chevy dealer and he says the GM part number for the 3.73:1 gearset for the S-10 truck rear end is P/N 26038402. Can anyone out there CONFIRM that this is the 3.73 ring & pinion set that will indeed fit the F-Body 10 bolt rear??? Thanks AGAIN for any and all replys

 

Doesn't Superior Gear make the gears that GM uses anyway? Do some research, and save some $$$$$$.
