I have a new 2013 2D sport model. I would like a little less body roll, and a 1.5 to 2 inch more lift. It sounds like there is a lot of different coil springs between the 2 & 4 door JK's. Is there a list of different part numbers for the coils from soft to firm & are there different heights? I also see new take off red rubicon shocks for sale, and was wanting to know how they comepare to bilstein 5100 shocks? I'm wondering if it is worth buying these take off parts or just go with an after market lift kit. Thanks for your help!!!

 

Jeep uses different springs depending on how heavy the Jeep is with options like towing package and hardtop. Springs are usually described using the last two numbers on the spring tag. Higher numbers are stiffer and using a 18/59 or 19/60 front rear combo on a 2DR will do what you want. Bilstein 5100's are a very good shock and what I've run on my last two Jeeps.

 

I swapped out a 15/16 (last #'s) set for a 17/18 set in the front and 58's for 59's in the rear. This gave me an 1" lift in the front and 3/4" in the rear. So if your looking for an 1.5 to 2 inches of lift, your gonna have to go 19's in the front and 60's in the rear and my thinking is your likely gonna be way closer to the 1.5 inch end of your scale than 2"s.

I have a 2 door Sahara which had 13/56's. I swapped to 19/60's. I got 2 3/8" in front with aftermarket bumper without winch. Added my winch and it settled to 2". No regrets here.
