i want to put a set of gears in my car that i will be able to tell a difference in, but also be about to drive on the highway and no have to worry about the RPM's. Should i go with 3:73 the car has 3:23 in it right now


thank,
Billy

guessing by the 323's you have a 6spd. Either way 373's are good in autos and either 373s or 410 are good in 6spd cars. I can do 75 at around 2k rpm in 6th gear with 410s

3.23 is an A4 ration not M6. I wouldn't go higher than a 3.73 in a A4 car. 4.10 is perfect if you have an M6.

A lot of people with A4 go with 3.73's and M6 go with 4.10's.

whatever u gotta tell urself man haha jk but u have an A4 so i agree with everyone else, 3.73 or higher...u wont be unhappy with it

I went with 3.42's, but I had 2.73's stock. Going 3.23 to 3.42 is basically a waste of money. 3.73's IMO is too much gear for highway trips and 1st gear starts becoming useless as it's more of a traction hazard than anything else. If my car had 3.23's stock, I never would have changed them But to each his own.

Is it worth the time messing with the 10bolt putting 373s in? or not worth it with chance of gear whine. There was another post somewhere about this but i cant seem to find it

so the gears i have in the car right now are okay???? i dont want a traction problem so should i just keep what i got and do LS6 intake and headers mabey?

ChocoTaco369

That depends. If you're not too well versed with modding the car, I wouldn't start out with gears right away. There are compromises with doing gears such as increased engine RPM's, decreased gas mileage, more traction issues, it's tougher on the rear end, there's the likeliness of gear whine in the install, it's an expensive install that pretty much has to be done by a professional and you'll need to have your speedometer reprogrammed or your speedometer, odometer and potentially shift points will be all messed up.

Modifications with the intake and exhaust basically have no downsides aside from increased intake or exhaust noise, which in many people's opinion is actually a positive. I know it is for me as I LOVE IT LOUD

I'd do some research and find out what you really want out of your car before you just go and jump into gears. I just got my gears put in on Monday and just yesterday I started getting a bit of whine between 45-50 mph. It may be a wheel bearing, I'm not sure. The gears need to be doublechecked in 2 weeks anyway. It could have something to do with the fact that I got shipped a set of Richmond's with a small chip in the ring

In your case, I would start off with a lid, a catback, a FTRA kit, headers and an intermediate pipe (y-pipe, x-pipe or h-pipe if you want to go with true duals), a ported throttle body and an LS6 intake...in that order. Many people will argue with my suggestion of the FTRA (Fast Toys Ram Air kit, basically a souped up cold air kit), but the guys you find arguing are always the guys that don't have it and have never even seen it. I have it, I installed it myself and I like it.

I would go 3.73 but since your worried about rpm I would just get a stall. 2800-3600.You also got to think of what your going to be doing to the car in the future. Like me, I was going to go turbo but deciding just a cam and a 100 shot. Hey Choco how much of a difference did you feel with the ftra ? I always wanted to get it but had mix reviews and I was also worried about water getting into the engine.

ChocoTaco369

There was a noticable increase in top end power above ~50-60 mph with the FTRA. It definitely is a worthwhile mod. The install's not too bad either, just learn from my mistake and use a jigsaw. Cutting up that plastic with a hacksaw was BRUTAL. I spent almost 2 hours cutting up the plasic, and when my dad came up to me and said "why didn't you just use my jigsaw," I almost popped a blood vessel. I was like "Dude...you have a jigsaw? AHHH!!!"

As for your stall suggestion, there's also a lot of compromises with that, like decreased transmission life, very expensive price and install, more cost from the installation of a tranny cooler and a trans temp gauge, decreased driveability in traffic, decreased top end efficiency, more wear on the rear end, severe traction issues that almost beg you to invest even more money into a set of drag radials (which SUCK in anything but perfectly dry conditions)...I personally went with gears over a stall because I felt there were less compromises with gears, and gears have a lot of compromises

well i currently have a SLP lid, SLP loud mouth, and a K&N filter. i would like to do MAF, TB, headers, i dont know should i do X or H pipe? LS6 intake, and mabey later put a stall in it.

so if i do those 6 things i listed how big of and improvement do you think im looking at???

lid, cat-back, filter, maf, tb, headers, stall, H or X pipe, and intake?

i dont think im going to go with the gears right now. i put some in my mustang i had and i wasent really impressed and the money i spend on having them done and stuff it really wasent worthet.

thanks billy

Keep the 3.23's and get a 3200 stall

with gears, make sure you get OE GM GEARS! They are US made Motives (or Superior US OEM gears), not the Italian Motives which suck. Italians will be 4.11 not 4.10 (thats another give away). The OE gears are available in 3.73 as well as 4.10. My 4.10's don't make any more noise than factory gears. Why? Bacause they ARE factory gears! Richmonds are too hard and brittle, you basically can't set them up in a way to make them quiet. Same with italian Motive and the other cheap gear brands. The OE gears will be more money and are harder to find, but well worth it as they are stronger and quieter.

3.73s

ChocoTaco369

As far as I know, you can't get OE Motive's for a 2 series carrier. You'll have to buy a spacer and get series 3 gears, and that's a lot more trouble than it's worth and a disaster waiting to happen.

I STRONGLY doubt a set of OE Motive's are stronger than a set of Richmond's. Research and opinions by both the end user and mechanics have lead me to believe that Motive gears are junk compared to Richmonds. Richmond may be a tad noisier in most instances, but they're a better quality. That's why Motive's - even the OE Motives - are so cheap.

Speed Inc. has them for $189, and they're only available in 3 series. I wouldn't buy them personally.
