Bumper Sag with Mopar Offroad Bumper/Winch?

I installed the rear Mopar Offroad Bumper and love it...

Now, I want to install the front Mopar Offroad Bumper and add a winch down the road. Will this cause any bumper sag? If so, what can I do and how hard is it to make right?

Thanks!

The weight might cause the springs to sag a little. If it does, a cheap easy way to fix it would be 3/4" spring spacers in the front. That might require you to change shocks up front (to account for the longer travel), but I doubt it since you will have the winch on there. I am lifting my Jeep next month and will be adding the spacers up front at that time so when I do add the winch, it won't sag.

I do have that bumper and a winch installed. I have a 3/4" to 1" sag right now. Where can I order these spacers you mentioned? ANd how difficult or easy is the install? The sag is noticable because I park my 07 Rubicon right next to another 07 Rubicon, easy to spot my sag, lol.

You can get 3/4" spacers from your local dealer for about $6 each. Just order two additional front coil spring isolators. Stack these on top of the existing ones.

They look like this:

Would getting stiffer coils instead of adding spacers have any advantage? (If there are any stiffer than the stock rubicon coils)

Stiffer coils have the advantage of retaining or increasing the suspension travel.

I ended up using stiffer coils on my Rubicon. Adding the bumper with a Superwinch EPi9.0 caused the front to sag 3/4" from stock. I had always felt the front was much lower than the rear on my JK so I replaced the coils with much stiffer ones. Now my front is 2" higher than it was stock. The JK is just about level. The front "looks" a little high so I have some new stiffer rear coils I will be installing soon...

Do you happen to know the part number for the stiffer coils...though I don't really want to be 2" higher than original in the front...anyone know any coils that should bring me back to normal? I want to retain my suspension travel for flexing, but also would like to return to normal height.

I have the Mopar bumper with a Warn winch. When I had my lift installed, the front end still sagged. A 3/4 spacer leveled it up perfect.
