4.30 to 4.88 is it enough

hi everyone my question is with me shortly going to 255/85/16s on my 17 utility cab sr 4 cylinder automatic which I believe my stock gearing is 4.30 ,is the jump to 4.88 going to be enough to get me were I would be if it were stock or should I wait to see if there will be another option like 5.29 which I hope will be coming out, if that would be the correct next ratio any thoughts or help is much appreciated being its a needed but expensive mod that I wouldn't want to do twice thank you all in advance for your thoughts and time

 

That was very hard to read without punctuation.

 

Keep it runnin' on......

 

I'm pretty sure only Manuals come with 4.3 while Autos come with 3.9. I may be wrong for the 4cy...

 

automatic 4cyl 4wd has 4.30
