Default Do 4.08 Gears Require Oil Cooler or Supporting Mods?

I'm considering the 4.08 gears for my 2007 HR Z and am wondering if I will have any oil temperature or oil pressure issues afterwards. It's just my DD with no much racing.

I don't see why it would but I just wanted to be sure.. maybe on a long interstate trip the RPM's could be a little high or something.. /shrug

Thanks,
John

Do not see why. Its just a final drive. Has nothing to do with engine oil pressure or temperature.

if your use to cruising at 80-90, then you may want to upgrade to a larger radiator.

it's cheap, easy to install and a little extra insurance for the motor. i would also change the diff fluid more frequently.

Really? Does the stock radiator just not flow enough? At those speeds, surely it's getting the coolant really cool..
