Got my gears on today by a performance machince shop. as soon as I broke them in a bit got on it from a idle roll and I was like great nothing new here but just before 2nd gear holy s***! It's like my car got a swift kick in the a$$. What is the break in time for gears anyone know?

 

I tried to go for 500 miles but only made it about 350 then all hell broke loose!!

 

Yeah I got back to the main strip of highway near my house a hour later. And this import came by honked his horn and tried pulling away. Caught him in no time and had 5-6 car lengths in a matter of seconds.

 

nice dude cool you like um... how much did it cost for you to get them installed

 

$215 and he even included the Royal Purple 75-90wt gear lube and he had a better gasket seat for the girdle. Took his time and was very careful I was impressed.

 

That settles it...I'm getting gears by the end of the month!!!

 

Don't fear the gear. It feels like the stock gears untill you get on it and it just hauls so much a$$. And havent really noticed a gas milage change just cruising through town like usual. Highway is just reving kinda high but not that big of a issue if you stay at a constat speed 75mph seems to be just right for me.

 

Congrats on the gears.

 

Same here!!! All i am hearing are GOOD things! Gotta get me some! So why are 4.10 better than 3.73's??

 

There is no break in period needed for gears. They are either going to work or not.

 

I agree.I did'nt waste much time seeing what they would do.

 

Because 4.10's help accelerate faster than 3.73's. Obviously the only reason I can see in not getting 4.10's is that your engine will rev higher on the highway but if your a local driver that doesnt go on the highway much your revs wont be too affected you'll just shift more often. Trust me just get the most out of gears go to 4.10's.

 

I like my 3:73's but will change to at least 4:10's or 4:30's in the future

 

I see EVERYONE only compare 3.73s to 4.10s. You people know that they DO make 3.90s, right?
LOL

 

Well how about 3.90's or 4.10's, havent heard anyone get the 3.90's?? I might go with the 4.10's, but i dunno

 

You are talking to someone with 3.90s.

 

Theres not much difference. But you want the most out of gears you'll get 4.10's

 

Well im sorry to kinda take over the thread, But throw me some knowlegde guys!!!!

 

Here comes another gear thread........

 

Well if someone could link me to a previous one! Id appreciate it!

 

This is all you should need information just ask if there are any other questions your iffy on.

Gear thread 1

Gear thread 2

Gear thread 3

Gear thread 4

 

Congrats on the new gears, and yeah the gear threads must stop!

 

Yeah hopefully my last reply will stop them I went through and picked out 3 pros and 1 con of gears, installation, and other tech stuff anyone should need to make a descion.

 

ok thnx!! icefreezen for the links!

 

Congrats man. Break in? Psh, I was redlined on the way out the shop...lol. I wish Id have gotten the 4.10s though, so definately get those.

 

The 3.90's are better for the automatics, if you have a manual, 4.10's are the way to go. I just had 3.90's put in my automatic and she hauls now..

 

I got my 4.10's last week, should go in pretty soon.

 

i totally agree with mattj, i asked the tech who installed mine, he said just like the old days, brakem in how your gona usem, backed out of shop and lit them up, what a rush,

 

Everyone else I've talked to says 4.10's are a minimum for an automatic... some even said to go to 4.56's

 

I'm going to run mine out at PIR shortly. I'll let you know what my ET's are.
Currently my best run is 13.89 with 3.73 gears.
I'll post new ET's as soon as I run.
