4.11's

So I've decided to order gears for my 2010 ss, and wanted to go with the L.P.E.'s but they don't make 4.10's or 4.11's.... So reading the forum it appears that the newer 4.11 richmond's are good, can anyone recommend where to order from and possibly the cheapest ,reputiable place to order from?

carry a bucket to pick up the pieces. Go with the LPE 3.91 from Janetty. You'll be very happy with the 3.91 as there isnt much difference between 391 and 411 gears. Can I ask, what other mods do you have?

The 4.11s are NOT immune to this:





These were mine and lasted 1000 miles.

BTW... I grew up in Youngstown!

It wont make much a difference. Especially with what you have already. 4.11 omay actually be too much for the power you have. First would be pretty much useless and you'd be fighting traction all the time.

Wait... you A6 or M6? I always assume manual...

After seeing your mod list... stick with the 3.91 LPEs for sure from Ted.

I had the 4.10s with a bone stock are and it was fun but as I have incresed power, I am going with the 3.91 next. I am currently back with the 3.45s after the failure of the 4.10s.

Also, quick question... I basically drive around town and hit the strip 2 or 3 times a year and store it in the winter. Car has 8000 miles on it vin #293, anyway with only 460 to the rear wheels would you recommend the l.p.e rear diff cover with the gear change? And also the bushing,etc change for another $200 plus?

Bushings for sure, the cover... meh, I dont know. Never looked into it. i do not know of one Camaro that blew out the rear cover. Lots of gear failures but nothing with the cover... I'll be frank, I didnt even know they made an upgraded cover.

No sweat...

Where you live in A-town?

My parents live off Mahoning Ave. My dad has a 2007 supercharged Mustang GT and my mom has a black Saturn Sky RedLine. I get to toy around with them when I go visit.

You ever go to any local events? Super Nats or anything?

I'd like 4.10's too but I'm not gonna risk my hard earned cash. 3.91's for me.

Yea, the more I check into this I have to go with the 3.91's. My main concern was the fact with the cam I wanted a decent gear to get me outta the hole easier. Cause the stock just ain't cutting it! The money ain't the big issue it's just that I want a noticeable difference that's all.

the higher the number, the harder it should launch. however, it will hurt you on the big end. a high number on the gear is basically a bandaid for not having enough power to get out of the hole with the quickness. granted, like the other guy said, there's not a HUGE difference btw 3.91 and 4.11, but i personally dont like either one. thats why i stuck m 3.46's back in when i beefed up my diff in the gto.

dont forget, your mileage will suffer with the bigger number on the gear too. i like my 26-27 mpg on the highway

Gottcha, C! The only difference was when me and my buddy put the cam in there was a big difference in the take off with the clutch, which I did fully expect....All I want is that takeoff/ launch back and I hope these 3.91's will get me that back and then some.

if thats what you're striving for, i'd say that should suit you just fine.

Just an update for you...

I just got off the phone with my dad and we were talking shop... he was complaining about his 4.10s saying its too much gear with his blower. His first gear is totally useless and he can't get out of the hole at all bc there is no traction.

He has the 2007 supercharged 3V Mustang GT. Its about 460rwhp.

thats more related to suspension and tire setup than gear. the higher gear actually slows the rotation of the tire, but shocks it harder at the same time, thus allowing the tire to grip better. what suspension and tire setup is your dad running?

LOL, I dont know. I know hes got a lot in it but I dont know the specifics. I do know he has the stock wheels because he likes the look, I am not sure on tires either. I rarely see/drive the car. I know it does KILLER burnouts!!!

The cover is made by LPW and the purpose is to streghten case and increase fluid capacity. As well it has bolts to load cap's.Pic's in the last page or so of my build journal.
