yeah, mine was a heavy duty long travel for the front of my truck, and he told me because of the size and weight that is was very hard to balance and shouldn't be used other than when in four wheel drive. So what do I do? Because of problems getting my rear driveshaft shortened (done at a local place), I threw the high angle in the back of my truck and drove around on it for 2 months. It vibrated some, but not anymore than the rest of my truck.

Now on the buggy I run those square drivehafts front and rear, and they work well. I've had the buggy up to 40-50 mph down some county roads back home, and they worked fine. wish I say the same about my steering. I've got mad death wobble

So what are good coil springs for a TJ? I want something that's stiffer than stock, probably about 3" lift springs, as that should give less than 3" of lift with my heavier jeep. The coils are sitting about 2" more compressed than on a stock TJ. And most importantly I don't want them to sag. I'd also like to know the cheapest place to get them.

Rubicon Express coils are the best.

Just priced 2.25 x .250 DOM at metals depot. $21/ft. I bought 3" stainless sch160 for less than that a few days ago.

What about them is the best?

holy damn that is a lot of money

rubi coils are known for not sagging, great flex, great quality, actual lift. just an all around good coil

OK, I've got some prices on Rubicon Express 3" TJ springs. $141 shipped. Since cheap springs would only be $20-30 cheaper I'll probably go with these. My only concern is, I'm wanting something stiffer than stock TJ coils. Will these be stiffer at all?

i think the rubicon express coils are a little stiffer, but they are also known to be about 1' taller than advertised, and they settle about 1/2 inch

rubi coils are stiffer but the guys that i have talked to wont give me a spring rate
im kinda in limbo with them but will end up getting their springs anyway. xj or zj coils will be stiffer.

Their spring rates are on Pirate somewhere in the Jeep section.

here they are

Look alot like I order the rubicon express tomorrow.

Find it odd that the rear is stiffer on most of those. The stock ones sure look alot thinner than the fronts.

Wait, its still before 5:00 in hippy land. Call now.

so wutcha gonna do with the coils that are on there now?

I was thinkin about the ebay.

They'd work good on somethin that's light on the ass end.
