after market coil overs

Resurrecting this thread...was anyone ever able to confirm the Eibach 2.0 rear compressed/extended dimensions?

Eibach compressed and extended lengths from our research. Not terrible in our opinion.

Front
Compressed Length - 16.6”
Extended Length - 23”
Stroke - 6.4”
Stock spring - 16” x 3” 450lb

Rear
Compressed Length - 15.76”
Extended Length - 25”
Stroke - 9.24”

Thanks man! I have a Rock Jock trac rod relocation bracket I was planning to install but Rock Jock specifies minimum 1.5" lift above non-sas and no less than 18" compressed shock length otherwise the bracket will contact the frame at full stuff. At 2" of lift I meet the lift criteria but looks like I'm well below max compression.

You’d be correct. Fun fact, that rock jock bracket was the exact reason I looked into this. The Fabtech bracket doesn’t have a disclaimer like the rock jock. I’m not sure if that means shock length doesn’t matter, or if they just didn’t take the time to figure that part out

Yeah, I was a little disappointed when I started measuring the bracket...they say it's a 2" relocation but it's closer to 2.5". I'm pretty sure it would still contact the frame even with the max 18" compression. It would probably befine for +3" of lift.

Bumping the thread in case this helps anyone else. Eibach just got back to me and confirmed with the following verbiage in regards to the Pro-Truck 2.0s:

"The rear coilover at full compression is 16.9" from center of lower eyelet to the top of the upper spring mount. "

"The rear coilover at full compression is 16.9" from center of lower eyelet to the top of the upper spring mount. "

What was your question to them? This is really odd shock length information.

What was your question to them? This is really odd shock length information.

Here is the initial question I asked, and included all pertinent vehicle information as well.

"Hello! I have the Eibach Pro-Truck 2.0 coilovers installed on my Bronco. I intended to add a rear track bar relocation bracket to re-level the rear track bar, but the bracket requires a minimum rear shock length at full compression to be 18.15". I could not find the measurement data of what these coilovers are at max compression. Could you please advise? Thanks in advance!"

Got it. Based on a quick search, looks like you got the RockJock track bar bracket. So industry standards for the measurements you need are not what Eibach provided. See diagram below, you would need to know compressed lengths from center of lower show bolt to the top of the top hat. This is basically measurement from mounting surface to mounting surface. You may want to send them the diagram below to request those specific measurements to clarify your question.

Example of rear compressed lengths for Fox, King, Ride:
Fox rear shock: 19.24"
King rear shock: 18.50"
Ride rear shock: 18.31"
