How much did the 4:10's really help?
For thoses of you that upgraded to 4:10's in you manuals. How much of a gain was there? I don't care about gas milage because it is a weekend dry day care only. Any regrets? Has anyone track tested your 4:10's to see what gains you got?

I do miss how long my 3rd gear was before, but it pulls so much harder now it's well worth it. I was waiting until I got my rims for my drag radials before hitting the track. Still waiting.
If you have any kind of vibrations at 75 or faster after getting the gears, try turning the rear of the driveshaft 180 degrees before doing anything else. Mine felt funny at 75-80 when cruising in 5th gear so I turned the driveshaft and it smoothed right out. it could also have been they tightened the driveshaft bolts too tight. 5 of them were really hard to turn and 1 was very easy. I guess they didn't read their ford service manual that says tighten in a star pattern to 41 ft lbs.
