I am looking at picking up some Hankook Dynapro MT 315-70-17 tires on KMC XD Hoss series wheel and have a couple of questions. I have a 2.5 inch lift... Do I need bump stops? What about spacers? Also I have the Dana 30 front with 3.73 gears and an Aussie locker on the front, will I be ok? What about the spare in the tailgate?

Thanks for the help.

 

your kit should have came with bumpstops to run 35's.

spacers are needed if you have more then 5" back spacing on those KMC XD's...

Dana 30 in the front is weak, people gusset and sleeve their axles to strengthen them up by 30%

Aussie locker will create more pressure on the axle.

Lock the rear. it's a dana 44

A spare on the tailgate will eventually cause your hinges to weaken and youll have the tailgate sag.
