Red face Newbie, need help do not understand the coil thing

Sorry guys, I have read all the threads pertaining to this and still have some questions. I bought my JK used there are some kind of spacers on it or so I was told. Took it to the jeep dealer yesterday to have it looked at for a shimmy and a rattle. Running DC mud country 33's . Jeep told me it was my tires. Nothing wrong with the Jeep. (2007 wrangler x). Tires are less than a year old. Went to where I got the tires and showed them the paper from Jeep. (Yes dumb woman here...LOL). They called jeep and then explained to me that I needed new shocks and a heavy duty steering damper. Before I order those I got on this forum. I would like a slight lift Maybe 2 inches. Read the threads about the 19/60 coils. Called the jeep dealer and they couldnt cross reference the numbers listed. They found the numbers and gave me prices. But could not tell me if they were 19/60's. I dont know how to find out what I have on there. Since it does set higher than most stock jeeps (of that year) I dont want to buy new ones if that is what is already on there. Can someone please tell me what I need to buy. Tires are cupping. And can someone tell me if I need single or dual steering stabilizers? I was looking at the rancho rs9000xl shock and their stabilizers also. Thanks to anyone willing to reply.

You only need one steering stabilizer on a Jeep. The cupping tires can be caused by bad shocks or a lack of tire rotations, a few other things too but that can be addressed later. Are you looking at coils because you want a larger lift?

Tires were rotated every oil change. And yes I am looking for more of a lift. But am concerned that the larger coils would make it ride poorly. It is my daily driver and light off-road. Read somewhere on this forum that lowering the tire air pressure could also help. Cant figure out how to check to see which coils are already on it. Thanks for answering!

on the part # of the springs, the last two numbers are what we use to tell us if it is a soft or stiff spring. fronts range from 13 to 19 (19 being stiffest) and on the back it's like 53 to 60 ( 60 being stiffest) there should be a white tag with the part# on each spring if yours are stock. you might even find different numbers side to side because of the gas tank on the passenger side
2dr's generally have 13 to 16 front and 53 to 56 in back, 4dr will have 15 to 19 front and 56 to 60 in back
hope this helps.

Should be a green tag on the spring. The number will be on that. Im running JKU Springs in my rear and got probably 2 inches of lift from them. The springs are all the same length just stiffer rates.

If you want better ride with the lift you want taller springs with equal or less spring rate. Look at the AEV or old man emu springs. They are known for their improved ride.

Thanks for all the input. Now I understand the coil numbers, but I still do not understand how to know which ones to buy. Do I buy all the same or different for each side? or different for front and back?

Sorry to semi hijack the thread but I have a 2013 JK Unlimited Rubicon. The front springs are 18s but with the Warn Stubby Bumper and Powerplant winch the Jeep needs stiffer front springs. How much stiffer do I need to go to get some of the squat out of the front end?

19 is the highest stock front

Most common fix is a 1" spacer

first, find out what springs you have on each corner and go up the same amount on each spring. front and back springs are not enterchangable.

What is the pounds per square inch on the stock 18 springs?
