getting ready to put a 4.5 on the cherokee, can i put a 1" spacer in the front with no problems, or will it cause issues

 

You would need new brake lines most likely. And maybe new shocks, but you will prolly be ok on those. You would also need 5 inch or 6 inch lift height sway bar links. Plus the front will sit higher then the back.

 

Won't casue major issuses. As long as you have an adjustable track bar. And if you are using fix arms it'll be a little harsh on the road

 

this is the kit im gonna use, i may not need the 1" in the front but i don't want and nose dive in the front.
