Gears... gears... gears!

Where did you hear that from? And what company's gears are you talking about? I'm just curious.

I work for Ford at the axle plant, and we make gears from start to finish. ALL of our gears are heat treated. Even if a different type of metal is used, is still SHOULD be heat treated which hardens them. All the gears we make here at Ford are made of the same type of metal, and go through the same process, reguardless of what axle size and ratio it is.

Heard it here on stangnet. A lot of people were having problem with a certain type of 3.90 gear, and there were only a few companies that made them at the time. But they had to replace them a few miles after they got them, and just...why get 3.90? go 4.10

But i wont be getting 3.90s. Just my personal thing after hearing about them.

FRPP doesn't make or sell 3.90s...

Okay, crew all that if you're staying N/A, GO 4.30 PERIOD...Had both .10's and now the .30's...no comparision...Just do a little to the susp and you'll be fine...and kicking some arse while you're at it!

Well from what ive heard from other serious racers is that the difference in the 4:10 and 4:30 is at the most a .10 in the 1/4. The 4:30s will get u into the pwr band a tick quicker, but your top end will be a tick slower as well unless u got the hrspwr to get u to top speed. I know some guys could care less about top speed, but being a police officer, I couldnt imagine being able to get to 145 mph/with 4:30s without some more pwr and the redline would keep u from it as well. I believe that if you have the pwr, u could go 150 + with no problem. The 1/4 would be a bit more fun with the 30's though!
