Umm... they're both pretty damn important. I will say that with 4.10s, new upper/lower control arms, pro-kit and street tires, I don't have any issues hooking up.

I think everyone ASSUMES good tires so........IF you have good tires, thenIT IS all about the suspension set up. Good tires by themselves accomplish very little. (Upper/lower control arms, subframes, front suspensions, etc.)

As to the OP's question about why 4.10's break more traction than 3.27's- it is all about torque multiplication.

The lower your gearing is (higher numerically) the more you are multiplying your engines torque through the drivetrain- this torque multiplcation is why it is easier to get a car going in 1st instead of 2nd or 3rd- your engine has the same amount of torque, but the lower gearing multiplies it more. When you put gears in, you increase the torque multiplication for every gear, but it is most evident in 1st and 2nd- Hence you break the tires free easier.
