Default Best rear gear and brand

Building a 370 and am stuck between a 373 or 410 rear gear. Also, what brand? Setup will be daily driven with a weekend here and there at the track. Let's hear those opinions.

if you want full potential from truck you will need a lower gear then 410

I'll be using a set of factory 17's stretched as a drag wheel. Probably end up with a 28 or 29 inch tire.

If 28s then 430s are good all around

Now if more race 456-488

If I ever build a NA truck again it will have gear for sure

Hell my daily has 488s but does have 35s

I've always said a 4.10 or 3.73 is a good gear for dailys. And I've always used oem gears, powertorque from oreilys is what I've used in past gear swaps and they have done great. He'll I've got a bnib set of there 3.73's sitting at home that I need to get rid of! I've also heard good things about motive and there prices are decent.
