I want to know what all i need to replace underneath to run 33's. Im tired of my 31's and i can fit them i have my fenders trimmed and ready but i heard once you go 33 and above your drivetrain gets weak. I only have the dana 30 infront and chrystler 8.25 in the back. Ive replaced the front u joints and regular maintanence but no real upgrades as far as the drivetrain is concerned. Please let me know everything i should take care of before putting on 33's and what can wait. Much thanks!

 

Put 33s on and run it. I'm running 33s haven't broke anything yet nock on wood. I wheel mine 3 or 4 time a month and drive it to and from the trail. If you brake then upgrade. Just go out and enjoy your xj.

 

Transmission cooler. Then wheel it.

 

Just run em.

 

I've been fine with 35s on stock drive train.

 

Plus 1 on the trans cooler.

 

Regear if you're running long term, otherwise just run em.

 

+2 trans cooler

 

Ok so trans cooler and regear

 

Just depends on how you drive it,Off road you could break things if you try hard and hold it to the floor the whole time.
