im not discounting your experience, just throwing some more in

corey had his on a spacer for 2 years about

valentine for 1 year

justin has for probably a little under a year (11 months or so)

geno cant be more than 6 months or so

well put it this way, do it right the first time. any form of work that contains the word "budget" isnt doing it right. the shocks and lift dont 100% have to be done at the same time, do the coils, save another 100 bucks, and do the shocks. then throw a bl in. done, the right way.

I just put the pucks on top of my 4.5"s and im expecting sag, hence im lifting the back 5.5" not 6.5". But will also be adding weight which will make it sag more.

do it whichever way you want, but me personally, I would give my friend 100 bucks to do it right before I let them put in those pucks.

I must agree that coil spacers sag. My best friend has a tera flex spacer/shackle 2" lift in his 01 xj and the spacer actually bulges out and has dropped at leasr 1/2" sinch install. I will take pics if I have to.

People are forgetting why they sag though. ITs because with the coil spaced up like that, it compresses more when flexing than it would normally do..

Thats what I would assume, correct?

I have only had my spacers in for about 5-6 months now, and they havent sagged at all. Actually, my truck lost 2" in the last 2 months, which is a good thing, because im actually flexing it out and she finally settled...

the only problem with spacers is like geno said, when flexing the coil needs to compress more before for the axle to reach the bumpstops.

and guess what!!!??

just like leaves you can extend your bumpstops just enough to prevent that overcompression so no sagging!

arent bumpstops amazing?

because your leaf springs were inverted when you flex, they can only invert so much. and leaves will last longer if you bumpstop them so they dont invert.

flex and leaf pack life dont really go hand in hand

but flex and coil life go hand in hand?

makes sense but thats not why they sag, they would sag faster if it was wheeled but about 90% of BB'ed tj's never even see a gravel driveway let alone flex. they sag because as the jeep rises there is more resistance on the coils, and they are pushed down on with more force at all times. hence saggage.

uh, who said that? same rule applies.

That makes absolutely no sense at all. explain your reasoning. there is nothing extra pushing down on the coils, the jeep doesnt weigh more. 2" isnt going to stress the stock steering/suspension, wanting to "pull the jeep down"

and even if it did, 2" coils will sag just as quickly.

um... stock uca's, lca's, steering, etc = binding and resistance. some full coils will sag just the same (rusty's for instance). ome's, re's, etc have a higher spring rate and are made of better material than the stockers.

argue with me all you want, bb's sag. its factual information. your arguing that the world is flat dude.

[KtmRacer419]

i dont know if you ever lifted your stock suspensioned jeep up by the body, but the axles will fall freely way more than a measly 2".

and the only binding going on will be between the tracbar and the control arm bushings, and even then the bushings will give ever so slightly to make up for that .2", not making the tracbar want to pull the jeep down.

if rustys springs are so crappy then i wonder how many of his 3" kits are sagging to stock after a year or 2.

my rusty's 3" springs have been on 2 jeeps, one jeep was wheeled with the stock tracbar for about 2 years and i wheeled with them for about 8 months with a stock tracbar. they didnt sag anything below 3" and im still running them.

The world is flat!! OMG!!

your right I've never lifted my xj or my tj. and your also right, she should get a bb. banning myself from this thread i've had enough of trying to teach physics to a monkey.

[KtmRacer419]

good call, this is just pissing me off the "physics" of all this is much too overwhelming for simple minded me

[DUG]

My Jeep flexes better and rides smoother with (6.5" coils) than with the (5.5" coils w/ 1.75" spacers).

completely irrelevant to the topic at hand.
