Spring Comparisons - Photos

As most of you know I installed a set of OEM SRT springs a couple of months ago and was disappointed with the drop. For those of you considering OEM SRT vs. SRT Eibach springs, I wanted to illustrate what sort of drop you can expect from each. Please keep in mind that I just finished the SRT Eibach spring install an hour ago so there will probably be a tad bit more settling.

My measurements with the OEM SRT springs were as follows:
Measured from center of wheel to top of wheel well.
Front - 18"
Rear - 18 3/4"

My measurements with the SRT Eibach springs are now as follows: (1 hour after install)
Measured from center of wheel to top of wheel well.
Front - 17 1/2"
Rear - 18"

I am now loving the look. It looks and handles much better than it did with the OEM SRT springs and I would highly recommend this setup.

Enjoy.

Re: Spring Comparisons - Photos

Awesome post - thanks for including the pics. I'm weighing up doing the wheel / shock mod to my 05' and this definitely helped with my decision!

Re: Spring Comparisons - Photos

Looks good. Did you replace the shocks/struts or kept the stock?

Re: Spring Comparisons - Photos

Thanks. I did replace the shock and struts. SRT Bilstiens on the front and rear. I originally replaced the upper and lower isolators which probably added about a 1/4" to the overall height but I expect them to eventually settle once they fully seat.

Re: Spring Comparisons - Photos

In november I installed OEM SRT coils and was also disappointed by the drop. I just went out and measured hub to fender.

Front 18.5"
Rear 18.75"

I believe my front sits high because its a 2wd. I can see your truck has the 4x4 markings before you debaged it.

Note: I reused my isolators, and the coils I installed had 30k used on them. I used srt bilsteins. Most of my seating took place in the first week. Measurements haven't changed since then.

I have questions, I understand it handles better. 1) Is the ride harsher? 2) Any issues with bottoming out?

Nice ride, wish I had the money for srt rep wheels too...

Re: Spring Comparisons - Photos

Thanks bobharly. It definitely feels firmer, more planted with the SRT Eibachs than before. But in a good way. No bottoming out yet and my wife put 80 miles on it yesterday and commented how much she likes driving it so it passed "The Test". I did not use any of the bumpstop/spacers that came with the SRT Eibachs. I retained the original factory bump stops that I had trimmed an inch shorter during the OEM SRT spring install. I swapped out all four springs by myself in under four hours. If you are still unhappy with your OEM SRT spring setup I highly recommend swapping them for the Eibachs. I am a happy camper now.

Now I'm off to order parts for the rear body conversion. ��

Re: Spring Comparisons - Photos

Ok, it's been a week. Remeasure to see where the height finally settled. The rest of the settling after this will be very slow as parts compress over thousands of miles. Thanks!

Re: Spring Comparisons - Photos

Front is now 17"
Rear is now 17 1/2"

I went for an alignment yesterday and they couldn't dial in the front camber. The mechanic said the lower control arm was pushed all the way in and the upper control arm needed to come outward but there is no adjustability up top.

NowI don't know what to do. I've read about the JBA upper control arms and also the Eibach Camber Kit but I really don't know which is the best route to take. I also don't know how everyone else here is able to have their front ends aligned without issue.

Suggestions?

Re: Spring Comparisons - Photos

Three quick questions:

1) What size wheels are they - the 20" or 22" ?

2) Would you be able to provide the vendors that you purchased from (for the shocks as well)?

3) When you installed the springs onto the shocks, did you need a spring compressor?

20"

PM sent. I don't believe I can post vendor names in threads if they are not supporting vendors.

3) When you installed the springs onto the shocks, did you need a spring compressor?
I did not need a spring compressor to install the new springs. Using my own weight I only needed to compress the spring 1/4" in order to get the top nut started. I had my wife thread the nut while I pressed down with both hands. Simple.
