What gears do I have?

285/70/17 tires turning 2500rpm at 80mph

 

you likely have 3.73 if you have a 2nd gen auto v6

 

2nd gen A/T 4.0 V6

 

put your VIN in here and see what your truck came with.

You can use the tire calculator to see how much variance your choice over stock created.

 

I know it has a yukon locker in the rear and lunch box in the front. Little scary on snow but a beast!!!

 

Surely you don't expect 'us' to know if your truck is regeared or not............

So you can figure it out for yourself. https://shiftsst.com/blog/post/how-to-determine-the-rear-axle-ratio.html

 

Welcome to TacomaWorld

 

if its already modified, then open up the rear diff and see whats stamped on it

 

I guess I went about asking this question wrong. My thought going into this was if I had put 4:88 gears and was running 285/70/17 tires I would know what my rpm was at certain speeds before and after upgrading. So I knew exactly what I was putting in my truck and why. Not because some youtuber told me it was a cool way to spend money that I have busted my ass for in construction for 25 years to earn. That way when one of my fellows from our society asked this question I would give him the data that I have from my upgrades to help him on his way. Thank you guys that had helpful info on this subject.
