Hellllllllo, thank you for looking and helping in advance. I have my 2010 jk mountain, it has spring spacers that it came with, no idea if it's a mountain thing but has the super lift shocks also. My bumper is starting to weigh it down and don't want to get a winch until it's not saggy. What exactly will I need? I was thinking 3" springs and an adjustable sway bar...thanks again )))

 

If i were you I would invest in a quality lift kit. I also stated with a 2" spacer lift, but the factory springs could not handle the weight of a winch and bumper. I now have the Rock Krawler 2.5 lift with the new triple rate coils and every happy so far. They handle the weight well, and it rides better that it did with the spacer lift by far.

 

X2. The stock springs are kind of soft. I have cheapo Rough country 2.5's and no sag problem. They are not as nice of a ride as the RK springs but hey they were free. RK 3.5's on the way.

 

More than just adding any old lift kit, I would figure out how much weight you anticipate carrying (i.e. bumper, winch, OBA, gear, etc.) and find springs rated to handle that weight. There is a ton of information on here and other jeep sites that will provide you with specific data.

Having the right springs will keep the proper balance of the jeep and eliminate nose diving when braking and strange handling when changing lanes or accelerating.

Here's an excellent thread that provides information about linear vs. progressive rate spings:
