I recently got the rough country 4.5in add a leaf http://roughcountry.com/jeep_xj_4.html and i was wondering whats the different from getting the add a leave or new leaf packs.

 

add a leave WILL sag sooner than later... new leafs might sag over time but will take a lot longer

 

How long does it normally last before it sags

 

that all depends on how wore out your stock spring packs are. do you know the the literal difference between the 2

 

between what?

 

add a leaf and full packs

 

how do i find that out. Sorry this is my first build

 

If your stock leaf packs have a lot of miles on them chances are they are already sagging. Slapping the add a leaf in will get you lift, but it wont last very long before it starts sagging back down.

Full leaf is the way to go.

 

with an add a leaf. you disassemble you factory leaf pack(only found in rear) and add an extra leaf to them. reassemble and reinstall. and with a full pak, you get bigger, brand new springs for the rear. so in essence,m with an add a leaf you are still using your old springs.

 

i have about 126000 miles on my current leafs so there prolly sagging? welll im not sure if they have been replaced or not

 

Post a pic up of your jeep from the side, can tell if they are sagging that way

 

this was 2 months ago

 

here is a bigger picture

 

Looks like they may be sagging just a tad...not a lot, but a small bit
Its kind of a give or take situation, they are going to sag regardless, the little add a leaf wont keep up the new arch for long...
New leaf packs are always the way to go.

 

Okay i just bought an add a leaf 4.5 inch. I guess i keep it tell it sags more then just get new packs?
