Spring Rate Question

2116 Views 6 Replies 5 Participants Last post by  dvn4life1972
I'm a little confused on how to read my Spring Rate Tags on my springs that came on my 15 Rubicon. What I really want to know is if my spring rate is on the low side or on the higher side of the spring rate that I could have gotten and if I would gain enough lift to make it worth my time to switch for other springs.
Front ---5212 or 6315AC not sure which # I should be looking at?
Rear ----4258AA
Thanks

15’s in the front and 58’s in the rear. Two doors will typicall have lower spring ratings than four doors. I think they go up to 19/60 or thereabouts depending on equipment ordered.
Yep, 15/58's... Not a bad rear spring, but a little short in front. I know some claim that it's spring rate, but there's also a following that believes the only difference is spring length.

I'd love for a race shop to throw them on a spring dyno and give us the facts...

A set of 18's in front would give you roughly 3/4" lift/level for very little $$.
oak,

It also depends on what you plan to do on the front end. Install a bigger bumper? A winch? Or just want it level.

I went with a set of 19 and 60 springs I found on ebay as dealer takeoffs from a new Wrangler that got a lift. I also added a Rampage bumper and winch, so I added 3/4" pucks to the front springs too.

Net result on my 2dr was 2" front and 1" rear lift. Perfect. level. No other modifications needed.

I could not see any difference in the spring rate from looking at the springs side by side. Same design and wire size. But the new ones are taller. That is the difference I see in the various springs. Just their length.

If you don't plan to add any weight to the front, just leave out the added pucks.

I probably should of stated that I have a 2 door Rubicon Hard Rock that I just traded a 12 Sport on. My sport had a 21/2 lift and 33's a nice stance.
Now my Rubi has more rake then I'm happy with and I want to at the very least to level it. No plans on much modding or adding a wrench, even considering keeping stock tires until they need replaced.
This is my 6th wrangler and everytime I seem to mod a little less, sort of the reason I went the Hard Rock! I really only do light off road stuff that any stock wrangler would be able to handle.
So my end result that I hope to get is slightly exgressive stance if compared to a stock Sport. The tires and bumper with the wings removed already does most of what I'm affter. Hoping to level and gain a little height.
Would the TF Leveling kit do that?

If you just want leveling, you can do just a 1" puck on the front. It's $32 and a couple hours and you should be nice and level. Mine is a 4dr., but this is what it was like with just the 1" puck up front.

On a side note...sounds like a nice Jeep.
