The brake kit should specify what vehicle it fits, if your wheels are not stock 17" then there is your problem.
WHAT SIZE WHEELS ARE ON YOUR JEEP?
WHAT KIT DID HE INSTALL?
I'll take that front 44 if it's available and you don't want it... much better upgrade from a 30. The 30s bend especially once you put 37's on it and use them..
Well my red Top that was in my Jeep when I bought it took a crap (only 3 yrs old) so I replaced it with this... not to many options with the reverse post set up. I went with this one.
