Default Looking to get a set of 3.73's, what all do I need?

Sorry I'm sure this question has been beaten to death but, what all do I need?

I got a buddy that build my trans and he said he can install my gears I just need to supply everything.

What brand should I get?

Is 75w90 sufficient? How many quarts?
I only need 1 GM additive correct?
What install kit should I get?


Links? Sponsors?


Thanks all

Car is a 93, 2 series rear.

I guess some more info is needed. Are you experiencing any problems (noise, vibration, etc)? What do you ultimately plan to do with the car (drag race, DD, road race, add horse power, trans swap, etc)? I'm pretty certain there are other parts you'll want to replace while you're digging around in there. Several factors have a bearing on this. The answers for staying at stock HP levels and DD-only would be very different from going full race.

With the build I see in your sig, you're going to need more than a ring and pinion.

It's a drag race / weekend car. I drive the car to work once a week TOPS.

Mods are in sig, new rebuild has ~600 miles on it.

No vibrations or noises. Around 50-55mph im around ~1000-1100 iirc.

I'm not looking to drop tons of cash in the rear as I may sell the car or upgrade to a 12 bolt.

Since you're running an automatic, the rear stands a chance of holding together. I'd say go for that Truetrac and axles. Bob
