Bump stops thread

[jggv98]

If I install to my KJ the following:

OME926 KJ FRONT MEDIUM COIL
NS130 FRNT LIGHT, JEEP LIBERTY
OME947 KJ REAR MEDIUM
N132 LIBERTY/KJ REAR SHOCK

Without front Strut Spacers and/or Strut Plates (for example the Upper Strut Plates Daystar that Frankenlift use)

How much lift i will get installing only the Coil Springs and Shocks?

It is possible to install this without Struts Spacers

I olny want to get 1.5" or 2" max

What else do I need to buy?

Thanks

That is what we have on my wifes KJ
depending on how bad the OE springs are and what year KJ you have
along with what other gear you have you should get about 2"

we had bad sag on the OE springs but nothing other than a custom made ****** skid for extras
we got 2" and some change from the lift after 3 years it is still holding the same and rides good
we run the OE wheels with no spacers and clear 245/75 MTR's

Thanks J

So i dont need to buy something else!

Thanks

don't forget bump stops! and just out of curiosity why not get the HD??

you dont need bump stops with the OE wheels
and I did not get the HD coils because they were wrong for my application

 

[tommudd]

yep no bumpstops just stack those coils up! If you don't think so ask ARB reps, they can tell you the number one killer of springs is stacking, but no why spend the money on bumpstops

flame on

 

[jsc7002]

you need new bump stops with every lift, 1" of bump stop of every 1" of lift, right Tom

 

[jggv98]

The bump stops that you are talking about are for the rear suspension, right?

front and rear
can make your own with hockey pucks in the rear, fronts use Teraflex # 0019301200

right and if my coils do not touch at full stuff then they are not stacking
thus I dont need them thus proper application
This is also why I made my own for my TJ
I wanted to get the most from my lift but maximize coil life

you must have me mistaken for another Jason

 

[ShafferNY]

So. Do you, or do you not need bump stops with an OME/Rancho lift if everything else is stock(wheels, tire size, etc.)?

Is there a place who sells EVERYTHING as a kit?

I know I can go to www.boulderbars.com and get the springs, shocks, struts and rear bump stops. Do they also sell front bump stops?

My goal is to get the stuff and install my lift this spring, or sooner if I borrow my sister's garage.

yes any lift you do you always need longer bumpstops, as for the front I know Terraflex carries them but I dont know the pn

apparently it varies from rig to rig
I dont need them on the KJ ,springs dont stack or touch at full stuff
front or rear
also the OME shocks I have work with the OE bump stop length
and the struts ,from what I have read, are OE length I have yet to kill mine

I am throwing this out there and I may be wrong
the reason that some are stacking coils and some are not may be due to the
number of loops on the coil and how tight they are wound
I have the Med. coils and even at full stuff they still have a gap between them ,not much but some
maybe the HD coils have 1 or 2 more loops on them making them stiffer
but having the same length at rest but taller when fully collapsed
thus needing longer bump stops

 

[ShafferNY]

Gotcha.

Thanks for the explaination.

I believe the OME HD's have the same # of "loops" as the mediums and light duty just the material thickness is greater for the HD's over the lighter coils which makes stacking easier.

Like I said I could be wrong
but even if the material is 0.1" thicker then 10 loops would = 1"
I seem to remember it being close to 10 loops on the front coils

I am a stickler for doing it right
if bump stops were needed I would have put them
the only way you can know for sure is to check and see

 

[J-Thompson]

How do you check them...You put al the weight of your KJ on one front wheel?

What if you do this...then land on that suspended wheel?

You must be registered for see images

Things go 'BANG'.

Now that may be an extreme situation, but think about this, talking rear only:

I lift my car 2,5" by fitting longer springs. My OEM bumpstops are designed to protect my OEM springs which are 2,5" shorter...Now, even if you do not get spring binding..overcompressing is still in order imo. Then the shocks: the Rancho's are aprox. 2,5" longer then the OEM. So before the OEM bumpstop reaches the axle they will bottom out. The OME shocks are a little bit longer then the OEM ones, I would try and protect them as good as I could by adding an extra bumpstop.

well first that is the only way to check things out
second why would it go bang? you should be going so slow that it just "floats" down to the ground if you can not then you are on a trail that is to much for your rig
lastly yes the Rancho shocks are longer than stock and they do NEED longer bump stops the Old Man Emu's ,however, are less than an inch longer than stock and the stock bump stops allow full compression of the OME shock with about .75" of compression to go
by the way the Ranchos that people are using are not designed for a KJ
the OME's are ,I think this is the case any way
you need to buy the OME's with an L behind the number to get the proper
"Long" shock for a KJ and if you are going through that then you know you need longer bump stops

Hey Tom, pass the popcorn.(popcorn)

 

[ShafferNY]

Okay. Put down the popcorn. I have another question.

Does the Frankenlift have extended bump stops?

I didn't see them listed. Are stem cushions the same thing or something different?
