Please feel free to correct my if I'm missing something here...

>>After I switched to 4.10's...No more problems<<
Can't contest experience like that, also can't explain it. Maybe somebody
dumped some Mr. T's medallions in your trunk. I'm just talkin the physics
of the whole thing here. If I swap my 3.55s for 4.10s, the engine can spin
my tires easier(the driveshaft gets 4.1 revolutions to spin the tire once,
instead of 3.55 revs). Therefore, with the pedal mashed, its easier to
displace the weight of my bed and lose traction.

>>(Ponder on this: If numerically smaller gears are better, then why do
most
of the track vehicles run 3.90 - 4.56.)<<

I think we're miscommunicating a little, I think lower ratios (big numbers)
are great and will make your truck get up and move. I don't think
numerically smaller gears are better, I just think they're easier to smoke.
I don't want to squabble over chicken feed here. Well, actually it's pretty
fun.
