Are their any tricks for installing a 2" coil spacer in a TJ?

Re: Are their any tricks for installing a 2" coil spacer in a TJ?
Ya, rears are pretty easy (like others have mentioned). I ran with
stock length shocks for a while, but they definitely were limiting
wheel travel, and I'm sure would have broken after a while. He should
probably get an alignment, too (mine was off after my install). If he
still has vibes, he *may* have to lower the transfer case a smidge.
Rare, but I had to. :(

OK guys,
I'm following along at home here, and I'm not getting it.
I can see how putting the 2" spacers on increases the total spring length
and the ride height, but I don't see how or why you would "need to" replace
the shocks, or why they would then break. Sure, if you want to get maximum
articulation benefit offroad, the shocks can be 2" longer to go along with
the lengthened springs. But if you kept the stock shocks, wouldn't they
just limit the maximum extension of that wheel?
Are you saying that you'd be topping out so much that you'd tear the shock
mount off or something? I'm pretty interested because I'd like to do a
small lift on my '98 TJ to compensate for heavier bumpers and an added
winch. I live in New England where we don't do a lot of rock crawling, etc.
So I only have 30" Kumko MT's on it. I don't need a 4" lift and it would
look kind of goofy with that much lift and my current small wheels IMO.
So maybe a budget lift is the answer for me too? I had just replaced the
shocks a few thousand miles ago with some new OEM take-offs, but they were
cheap as dirt. Maybe the best bet is getting a set of *good* shocks along
with the spacers.

Re: Are their any tricks for installing a 2" coil spacer in a TJ?
Yes, we are all saying that using shocks to limit axle travel 'will'
break something.
I have seen the repeated impacts snap frames, snap off shock towers,
punch shocks right through the body into the back seat, etc...
Even with 2.5" lifted shocks I managed to snap off the bottom shock
mount on my CJ7 when the back wheel dropped into a hole fast. (it was
already slightly cracked from a rock impact, but...)
There are two ways to lift a TJ.
One is longer springs for more travel. This requires a shock with a
corresponding longer travel.
The other way is to put a spacer on top of the spring for increased
ground clearance and to fit larger tires. This does not increase the
travel or articulation, just raises the vehicle. For this kind of lift,
you only need shocks that are taller, they don't need to move more.
Then an extended bump stop is very important. This limits the
compression so you don't over compress the stock spring.
I am of the belief/impression that the skyjacker kit is designed to
destroy the stock shocks in short order so you have to go back and pay
big bucks for the 'longer spring' lift kit. They do this by shorting
the bump stop so the spring will over compress and sag out sooner than
later.
You know, a 2" lift with 1" higher bump stops....

Re: Are their any tricks for installing a 2" coil spacer in a TJ?
Yes, we are all saying that using shocks to limit axle travel 'will'
break something.
I have seen the repeated impacts snap frames, snap off shock towers,
punch shocks right through the body into the back seat, etc...
Even with 2.5" lifted shocks I managed to snap off the bottom shock
mount on my CJ7 when the back wheel dropped into a hole fast. (it was
already slightly cracked from a rock impact, but...)
There are two ways to lift a TJ.
One is longer springs for more travel. This requires a shock with a
corresponding longer travel.
The other way is to put a spacer on top of the spring for increased
ground clearance and to fit larger tires. This does not increase the
travel or articulation, just raises the vehicle. For this kind of lift,
you only need shocks that are taller, they don't need to move more.
Then an extended bump stop is very important. This limits the
compression so you don't over compress the stock spring.
I am of the belief/impression that the skyjacker kit is designed to
destroy the stock shocks in short order so you have to go back and pay
big bucks for the 'longer spring' lift kit. They do this by shorting
the bump stop so the spring will over compress and sag out sooner than
later.
You know, a 2" lift with 1" higher bump stops....
