i´m waiting for a 1" Body Lift and a AEV Snorkel.
is it necesary to disconnect the batery before lift the body?,..
i had read that it´s necessary to disconnect the batery to avoid problems with the airbags.

 

check out the post post titled "weird body lift problem" just above yours.

 

Yes you should disconnect the battery

ok, thanks so much, this is exactly the BL i purchased. I´ll desconect the airbag before start the install.

Otherwise, i´m thinking that there would be a little gap between the grille and the front bumper, isn´t it?

 

As a general rule it is normally wise to disconnect the battery before doing much of any modifying on a vehicle, anything electrical is a no brainer, but when your messing with the frame (or anything else that MIGHT have a ground strap nearby) the extra minute and a half (if that) to disconnect the battery is just plain worth it.
