I got a 95 Formula M6 with 3.42's, I'm looking to get 4.10's in soon at some point. Two questions. I'm looking at an install kit from Jegs that also include the ring and pinion gears themselves, it APPEARS Jegs manufactured the ring and pinion gears, does anyone have good experience with Jegs ring and pinion gears?. My second question is, what do you think a normal shop would charge if I were to bring the car in with all the parts, so basically just labor? I'm guessing $350ish? I'm located outside Minneapolis, Minnesota.

Here's the ring and pinion w/ install kit:

Jegs(and Summit)do not manufacture R&Ps',just relabeled of some major manufacturer.

Best advice I can give you is not to use 4.10's. Look into some 3.90's.

4.10s are awesome behind an m6, we've all been over this before. And as stated jegs and summit don't manufacture anything. I personally would buy motive gears so at least you know what you have. Gm75410 is the part number.

There not. But if you want a cookie cutter build then those are what you use.

Wow, WTF? There's not enough difference between 4.10's ans 3.90's to even tell without watching the tach...

I 'll jump on that 390 train ,i love mine .I wont say 410 gears are no good ,but for mainly steer use the 390 is the better choice.

ramair 1

iTrader: (2)

thats street use ,

There is actually. It's larger than you think (6 mph at 5800 in 4th). Another benefit of the 3.90 is they are stronger than 4.10's. Just as 4.11 is a stronger gearset than 4.10. Not many people know that.

besides I have never figured out why anyone would want to gear a car to run 102 mph at peak power(5500 in 4th for a bolt-on ls1) These cars go much faster than that in the 1/4 stock.

Truthfully I like 3.73 for a bolt-on car. It's the better gear for a street car. 3.90 is better at the strip. Just have to gear it for what you intend to do with it.

iTrader: (96)

Yeah, you are partially right, but with a heavily biased opinion. Stronger? Not enough to matter, for one reason there is a good chance you'll break your posi/axle or torque arm or something else before the gears anyway. 4.11 vs 4.10? Again, not enough to warrant even talking about. You're one of those paper racers, and 3.73s look awesome. That's great, but I'm a realist. If you are tracking/seriously modding your car you ain't staying bolt-ons for long (meaning torque lost lots of times and powerband higher in the rpm range), you definitely ain't shifting anywhere even remotely close to the 5xxx range, and if you need that last few mph in the 1/4 you'll up your rear tire size or shift point.

So, in conclusion, those who want to drive ms. daisy, please select 3.73s for your driving pleasure. Thank you and come again.

Chevyman5436

I have looked at 3.90's and I like those as well. Everyone kept telling me just to go 4.10 though. I suppose there isn't a major difference acceleration wise but the added strength should be nice. Does Motive or Richmond make a 3.90 for a 3 series carrier? Last I looked, I couldn't find any for 3 series and that's what sent me to 4.10.

3.90 Motive should be G875390, that's their orange box version.

LOl.....I've had or drove every gear from a 3.23 to a 4.56 in a m6 f-body. That's pretty good credentials for knowing what gears do what. Just recently helped a bud but a mild bolt-on m6 ls1 run a 11.96 @ 116, car didn't have headers...............AND IT HAD 3.73's....... Your not gonna get to 116 traps with a 4.10/411. So far my paper is looking pretty good.

As far as the taller tire is concerned you can do that. Alot do. I don't because it's dumb to. Why gear it where you need a taller tire to get threw the 1/4? The gear will use more power and the tire will use more power. And why the hell would anyone put a taller tire on a 10bolt???? Are you trying to break it?

Not serious if your just doin bolt-ons???? Really?????? Check the sig bud. Alot of guys much more serious than me (according to you) aren't getting 130+ traps.........and I just have a bolt-on ls6.

The gears on the ring gear of a 4.11 are thicker.(9/37). The 4.10 (10/41) as you can see has more teeth on the ring gear thus making them thinner. The problem I have seen is the teeth break on the ring gear of the 4.10's. Thus a thicker tooth of the 4.11 makes them stronger. I have had both......and I never broke the 4.11. Then I changed to the 3.90......so I could get threw the 1/4 w/o hitting the rev limit. Now I don't break r&p's, I break axles.

How's that for putting the facts on paper? And backed up with real results. Did you learn anything? You should've.
But I do agree with you on 10bolt strength. There not great but better than people give them credit for. If you don't let them wheel hop the don't do to bad.


3.90's and 4.10 would take the same carrier as 3.42.

01ssreda4

iTrader: (96)

Boy I bet the peanut gallery believes all that crap. Why would anyone want to gear up or OVER gear just to put a taller tire on an M6? If you are asking that then I know where you're experience level is. I'm done talking to you fella, it's a waste of my time. The reason is because people like you just like to argue instead of listening to real experience. Guess what, I went to the track last TNT night, wanna know what the fastest cars at the track had in common???? Big tires. Perhaps you should go wow them with your expertise there sir.

I'd also def go 3.90s over the 4.10s.

I had 4.10s in my full bolt on M6 LT1 Z28,

I did 4.10s because everyone said, m6 go with 4.10s - a4 go with 3.73s.

Well let me tell you, It sucked, its too much gear. I ended up hating driving the car unless there wasn't a car on the road.

Now w my current LS1, just did a gear install a few months ago. Did 3.73s and could not be happier. Want a lil more? do 3.90s. But from experience I wouldn't do 4.10s.

Great way to cop out bud. You really proved your point.

01ssreda4

iTrader: (96)

You want everyone to believe that 4.10s are slower. You've plainly insinuated that. I dug up some graphs of the fastest list......ya know just so everyone doesn't think you made me "cop out". What an f-ing joke

Hey maybe you should get a new hobby, cause proving people wrong on the internet doesn't really seem to be what you're good at.

^^^^ great comparison. OP with a mild lt1 can really use that info. So what tire heights were they all running? What rpm's were they all turning? All this affects the speed they can go greatly. But I'm sure you know this because you read it on the internet.

Take a look at # 2 on the SI list......I'll be damned he's running 3.73. You failed to high light that to try to prove your point. Funny how that works.

Looks like I proved you wrong just fine.
