Edelbrock Shocks for JK's lengths

Based upon taking the JK and gradually flexing it, it looks like, w/o extended bumpstops, the compressed limit is roughly 16" eye to eye.

If you then droop it, and unclip the wires and lines that go taut, you can make the mounts for the shocks ~ 27" apart.

The stock shocks only go to ~ 22" extended, 14.5" compressed (~ 7.5" of travel).

IE: A shock that would allow the disco'd JK with stock arms, etc...to flex as far as they go, would compress to 16", and extend to 27" (11" of travel).

Obviously, compressing shorter, and extending longer, would also work, leave room for improvements/buffer zone for individual JK variations, etc.

As simply adding coils or spacers, etc...would NOT add to the droop, merely PRE-DROOP the suspension...and adding bumpstop extensions would merely ROB UPTRAVEL....

...new arms with more range of motion would therefore be required to take advantage of shocks longer than 27".

The amount of lift in of itself will not affect that.

If the shocks cannot compress to 16", then stop extensions might be needed to avoid over-compression, etc.

I'd rather see a BL/fender mods, than stop extensions, IF JUST to avoid larger tires/fender hits though.

Thanks!

Now I can get rid of the ~



So - that is correct, the stock shocks currently limit articulation on the stock JK, as they only extend to about 22" (22.0 Front, and 22.6" for the rear).

The stocks compress to about 14.5" (14.13" F/14.75" R)...but, if you compress the JK, the mounts only get to about 16".

(Hey, throw in the decimal points while you're at it...all data is good data )

That means we can maximize travel by taking advantage of the ~ 16" compression range, allowing more shock body for a longer travel after market shock. The 16" - 27" range is not that hard to spec either.

What I also need, as I have not done the math/dynamics yet...are what the rebound and compression ranges should be....as lengths are good for fitment, but, the valving makes it work or not as far as performance goes.

That's harder, as heavier tires and axles, specific spring rates and roll centers, etc...are going to make the "correct valving" a crap shoot for a general after market application. (A lot easier to set up one race rig with known variables, than to guess what unknown people MIGHT be running...)



I typically bide my time, and pack my own shocks. Its the best way for me to get what I want.

The JK's a DD....so, I can mess with it as convenient.





Hey - You have Edelbrock data - Any other shocks you have data for?

It would be a great resource for people to cross reference what's out there!

OK, here goes:





I can update it, and then upload the new pics, etc.
