I have a 06 ford ranger sport with a 3.0 V6 & it has 3.55 gears in it now (Stock) with 8" lift running 36" iroks. Its kinda slugish so im thinking of going with Richmond 4.88 gear and pinion set. My question is will that be big enough to run my 36s?

 

4.88s should be fine

 

I would go with 5.13's.

 

Kinda is an understatement. I can't even imagine how much of a dog that is.

 

4.88s should do the trick but you may want to consider even more than that. Post up some pics of that beast!

 

Me too.
