Yea I would be interested in the spring rates compared to stock. If they can get even close to stock. I would reason buying a set.

 

See here's the thing though caveman, you keep thinking its about the flex, long arms aren't just about flex!!! We have gone over this many many times with you with me/atmos both showing its not just about flex that people get long arms for.

Sensitive *****: have you checked your shackle angle? That can more than likely cause a rougher ride, second, shocks are the biggest leading to a rough or soft ride, shocks are meant to dampen and allow for a smooth and soft transition from compressed to uncompressed movement and vice versa. Caveman is wrong about the shocks, yes the spring rate on coils and leafs can make some difference but shackle angle/shocks/ control arms angle are the biggest players.

 

holycaveman i'd like you to go measure the angle your lcas are at now.
keep in mind that stock is FLAT, HORIZONTAL.

i know you're not gonna understand this at all since you think relocating your shackle angle only makes a difference if it's POINTING FORWARD but every degree counts, front and rear, suspension, steering, anything.

if it didn't auto makers would pay ****ty mechanics to design their vehicles rather than engineers

 

Am I the only one who got better ride quality from short arm lifting their xj? I swear if I hit a speed bump the front just maintains it rather then shoot me to the roof like it did stock and my rear just follows but doesn't jump up like stock, I hated hitting bumps on the high way when I was stock. Now I don't care, I'm much more confident with road conditions lifted then when mine was stock. I think if I had a rear aftermarket bumper to weight the back down a bit then the rear would just glide over bumps too

 

Granted my front stock shocks were shot, my RC short arm lift with 32s at about 30 PSI rides like I'm on a cloud now compared to pre-lift

 

I know the purpose of long arms more than you think. And a two or 3" lift does not have enough fall in the control arms to warrant a harsh ride. Not to mention my lca's are new adjustable ones. With quality greasable joints. I have the front extended an inch over stock.
Nothing loose or binding, all greased. New bearings and joints.
My shackle angle is set perfectly for my spring arch. Which is just a little less than 45.
I keep on top of this stuff.
What you don't realize is I am not debating or arguing. I know for a fact its the front springs. As soon as I installed them is when the jeep rode like a truck. Caveman is not wrong, spring rate can make a huge difference. Yes what you mentioned can too. Like I said I have to fix these types of things at work quite a lot. You have to look at everything.

 

it's still not going to ride very well when cycling the suspension fast. a good bump and the arms still jolt hard

not worth messing with until you have long arms. once you have long arms it might be worth it to mess with spring rate. progressive coils would definitely be worth looking into at that point. you're still not going to get around the short arms crappy radius by changing out the coils.

 

That's probably why most auto makers don't use a 45 right? LOL

No offense but you did not, and still don't understand what I was saying. Not all springs are created equal. Tell me what happens if your leaf spring is close to flat in ride position. Your shackles are at a 45. What do you think happens on larger bumps? How does the spring react when it has to pull back in the shackle that is at a 45?

Not all springs are alike, not all set ups are alike. Some factory springs mount the shackle upside down at a 90! Some of them work on an inverted platform. So when you throw out a must figure like a 45 then you better had know the spring and application.

 

If I come across a used set and can mount them in the frame rails. I may just do it this winter. Then I at least will give an honest assessment of how long arms feel compared to stock.

 

that's the best way to go about it. loved my T&T's but never woulda paid full price. just try them out and see. the long arms allow the suspension to cycle up and down easier instead of damn near forward and back. a good pair of coils with your choice of spring rate can definitely make a difference when they're allowed to cycle the way they're made to

but with the short arms you might as well be throwing $$$ at a wood wagon. you may see results, but not enough to matter

 

I just spoke to Skyjacker, and here's what they told me about spring rates:

Front springs, JC30F: 218 lbs/inch
Rear springs, JC25R: 140 lbs/inch up to the overload spring

Compare those to this sample I've found here:
The Skyjackers are just about in the middle.

 

Hmmm, this big long debate and radius arms have been the only long arm system mentioned.

Seems to me that the folks that are more interested in ride quality would be much more interested in a 3 or 4 link system considering they're actually designed to maintain alignment through articulation, unlike a radius arm set-up.

 

I'll say... Rusty's springs do ride nice.

 

It's more of a discussion about the ride quality of 3" lifts, which are pretty much always short arms.

 

FWIW, My 3" lifted Jeep rides just fine.

The rear is a little stiff but the front is way better than OEM.

Big *** WJ control arm bushings helped a lot.
