I ordered this kit because I have the Rubicon with NITRO shocks, so to save some money for the time being I ordered the kit with the shock extenders.

I was reading WOL's install and noticed that the rear stock isolator is installed on the rear spacer then placed back on the Jeep. My question is can I leave this spacer out to level the Jeep? Will this cause the the shock extenders to bottom the shock out?

TIA,
JK

 

The shocks don't really have anything to do with leveling the Jeep. That is purely the springs and spring exstensions. If you did leave the shock adapters off you would probably over extend them on full droop and blow them.

BTW I like your name, Juliet Kilo i'm sure most people miss that.

 

Thanks for the reply but i think you missed what i was saying. i am talking about the stock spring isolator that goes over the tf boost spacer.

i was asking if this would cause the shock to bottom out due to the lessened lift in the rear.

 

You still need the stock coil spring isolator. That is what cushions (isolates) the spring from the frame. Without it, you will get a lot of unpleasant noise and general clunking from the rear suspension transmitted through the frame to the interior. Trust me, you won't like it!

If you're asking about the Teraflex spacer, well... why would you want to leave that out? That is what is giving you your lift. Without it, you might as well not do anything to the rear at all.

 

Sent you a PM

 

I know exactly what part you are talking about, as I did 1" teraflex spacers in the back on my JK. It's a clever idea, to leave them out for leveling purposes, but I don't think you would want to do that.
As sickchilly said, it will lead to a lot of excess noise. They seemed to be made from a different, slightly softer material than the boost spacer that comes with the BB kit, and they should quiet the ride down a bit. They are also molded specifically for the spring to nest in, where the TF spacer is molded to nest the isolator. I don't know how much difference that would make, but I'd bet the guys at TF wouldn't advise it.

Hope that helps.

 

Interesting series of cross conversations.

Just some clarifications:

1) The axle doesn't droop further because of the coil spacer...that just raises the ride height by that amount....so, leaving out part of the spacer's height would lower the ride height, but, not change the amount of droop.

2) The stock shock is what stops droop first on a stock JK....the extender just lowers the shock, so it starts from a lower point.

3) Using the lowered shock mount (Extender) simply means the top of the shock is lowered, so that the stock shock doesn't stop the droop as quickly (The total wheel travel stays the same, as its the same shock...and, you have to add longer bumpstops to prevent over COMPRESSION of the shock on full uptravel...but, you just made the travel occur at a lower range.

4) The coil spacer is not what stops uptravel...the bumpstop stops uptravel...so a shorter coil spacer would not cause over compression of a shock. (The extender could cause it, but, that's why you need longer bumpstops...so it doesn't)

5) If the stock shock was not pulled apart when it stopped droop before, its unlikely to be pulled apart when it stops droop at the end of an extension...its the same shock stopping droop, in the same way.

6) Everyone now seems to understand that the softer part, that goes against the frame, isolates vibrations, and helps to SEAT the spacer, so it doesn't shift, etc....and WON'T DO ANY of the other things it was accused of one way or the other.



OK, back to my reports...

 

Thanks TEEJ, I have read similar posts by you in the past. I agree but the question is can I just leave ou the rubber isolater in the rear that came with the Jeep? Just wondering how much the ride would change and if it would transfer more vibes and shock through the suspension.

 

The isolator isolates the noise/vibration...you COULD leave it off, and live wth the harshness.

What I would do instead though, is to keep the bet of both worlds.

Simply cut/grind off (etc...) the part of the SPACER to reduce the height of it, and then seat it onto the isolater as designed. Pick a side of the coild spacer to take off that will be easiest to preserve any contours needed to seat peperly with its intended mating surfce (A flat side would be perfect, etc...)

That way - you get the isolation of the isolater, and the exact spacer height you wanted.

 

I am glad you brought that up... I was already thinking about that. But when it comes time to upgrade from the upgrade I want to be able to sell the lift and rubicon suspension. If i go cutting it up it wont be worth anything come time for resale.

I think I will just leave it in and live with the small rake. I actually do like a little bit of rake so no biggie.
