Have a 2013 jeep Sahara. I am running 35x12.50r17. With a 2 1/2 inch skyjacker suspension lift. Should I regear?

 

Only if you are unhappy with the current gearing. It's not required.

 

Any problems for the engine or tranny wear?

 

You'll have other issues from the 35s, but tranny and engine are fine.

It would help to know what gearing you have now though?

 

I believe stock gears are 3.21. What other problems will the 35's give me

 

Everything will wear faster. Breaks ball joints. Unsprung weight (ie:axel. Tires) is something like 4 x harder to move and stop than sprung weight. Bigger tires, more weight

I dont always drive where others cant. but when I do, its in my Jeep. Stay muddy my friends

 

Actually 3.73 I think now

 

Your build sheet will say. 3.73 is an option.
