Default Gear Swap

Time to get rid of the 2.73 gears. Should I:

1) Obtain thick gears and TA cover package from a sponsor on this site and have local shop install - Parts and Labor approx 650 - 700 - no warranty

2) Obtain gear package w/ Auburn unit, OE gears and TA cover from different sponsor on this site and have local shop install - Parts and Labor approx 1100 - 1150 - no warranty

3) Have local shop obtain and install OE gears and Auburn unit w/ stock cover - Parts and Labor 1000 - warranty

how about none of the above, and **** canning the 10 bolt for a new 12 bolt!! for the money your willing to shell out, a 12 bolt is right around the corner and a much better rear end.

well Yes I agree also, I have a 9" and love it. Just saying a 12 bolt cause he has a auto. In any case don't waste your money on a gear swap in the POS 10 bolt.

out of the options posted i went iwth the cheapest and first option... but i agree at the poitn of spending over a grand on your 10 bolt, y not buy a 12 bolt with the gears you want installed...

Where can I get a 12-bolt for a grand? Prices I'm seeing are more like $2200 - $2500 plus whatever labor to install. I'm not completely mechanically retarded, but a complete rearend swap is probably a little out of my league

well i guess i was going by used prices... if you feel safe buying a used 12 bolt, or new but second hand... i've seen plenty for under 2k... some for even 1200ish if u wait long enuff... in the long run its probably the best investment, i'm going thru the same decision as you are... whether to get gears or save up for the 12 bolt, i figure i'll keep saving, and if i break my 10 bolt b4 i have enuff for a 12 bolt, i'll get the gears and such... if it holds up... 12 bolt for me.

What has been your experience with these gears? My main concerns for now are gear noise and durability, but I feel that shouldn't be an issue if they are set up properly since I'm not doing a lot of dragstrip-type launches. One of my other concerns is if a local shop will take the same care installing a part they are not warrantying. I guess that comes down to a trust issue and if I can't trust them I shouldn't be doing business with them...

i would suggest getting a solid pinion shim to replace the crush sleeve, i have ran richmond,jegs brand, and motive gears, noise is not an issue if setup proper, i did kill the pinion on the richmond gears but they were done while i was in iraq so i dont know how well they were setup. i set up the others and had no issue with them. the jegs gears are still perfect shape after running for two years, i took them out(3.73) out and put in new 4.10's they are still in the car but i no longer have it. the owner is currantly in iraq. what gear are you wanting? he may still have those 3.73 thick gears in storage.

I live way out in BFE, so anywhere I go is at least a 20 mile highway drive - so I'm leaning towards 3.42's. The sponsor I talked with has the thick gear made by Strange - Any experience with these gears?

thanks for your help - Since I've never done this job I'll probably be using a shop like I said - what should I be looking for? What questions should I be asking?

A budget is a budget, but just FYI, Ims ure you can swap the entire rearend when it comes time. Its not bad at all. Just dig in. If it makes you feel any better I have a friend that has been pulling his 17's off the ground in his Z28 at the strip for a long time on his 10bolt. I just flipped for the 9" while I could.

Thanks for the encouragement - Actually talked to a guy today that is pretty mechanically inclined and he's been wanting to do a gear swap on his car also. He's never done one, but he's manged to get some free parts, so we're going to do his first to learn on and then do mine. Seems like a pretty good way to learn - worst case, we screw his up and we're not out anything but time. Best case - we learn something and improve our cars ourselves - how cool is that? So I guess I will be "digging in."

I was saying removing and replacing the entire rearend isnt so bad. The actual gear install take alot more precision. Not saying dont do it, but just make sure he or yourself has the proper measuring tools to spec the gears in, and do as much research as you can. Some may tell you that you can just slap them together without the fuss of dial indicators and pinion depth guages etc. I say no way.
