Newbie question here about SRT8 springs

Hello everyone I just joined the forum a couple days ago and just purchased a 2005 Grand Cherokee Limited with the 5.7. It is trail rated with the tow package. I purchased 20" SRT reps and some stock SRT springs. I know it is suggested to upgrade to the Bilstein shocks as well and I am planning on doing that in the future, but for now I am wondering how the ride will be with the stock shocks. I am worried about the difference in spring rate with the aggessive springs vs dampening rate of the shocks. I'm sure you have seen this asked a million times and I did search but did not come up with what I was looking for. Thanks for your help!

Re: Newbie question here about SRT8 springs

You'll find more info in the WK forum ('05-'10) instead of this WK2 forum ('11-'15). The OEM WK shocks are longer than the SRT Bilsteins so you're going to wear them out prematurely. The SRT springs are definitely stiffer and you'll really start to feel it when you have passengers in the back seat or when you're hauling something heavy. Being an '05, the OEM shocks are probably due for a changing anyway. My recommendation would be to do the SRT spring install WITH new SRT Bilsteins at the same time. Otherwise, you'll be doing a complete spring install twice along with having to do two wheel alignments. You'll end up spending more money and time than if you just waited and did it all at once. I did the SRT spring and shock install on my '06 Overland. I would also recommend replacing the spring seats (both upper and lower) while you have it all apart. Good luck with the install. You'll love the results. Consider upgrading the rear sway bar to the SRT8 sway bar. Much heavier duty and it makes a world of difference.

Re: Newbie question here about SRT8 springs

Thanks for the response, maybe I will just wait to do the shocks and rear sway bar all at the same time. I will be towing a boat that weighs around 3000 lbs, do you think with the boat and 3 or 4 people riding inside it will be a terrible ride? If so maybe it would be wise to just leave the stock equipment on.

Re: Newbie question here about SRT8 springs

I wouldn't want to tow anything with my setup. I cringe when I hit a large bump with three other people in the car. The people in the back don't say anything but I know they felt the impact. You would be riding pretty close (if not touching) to your bumpstops. You will LOVE the look but in your case I would recommend keeping it stock. Probably not what you wanted to hear.

Newbie question here about SRT8 springs

Stay away from Bilsteins. I ran them on my '08 for 6 years and hated them everyday. They progressively got worse over time. It got to the point where I was going to swap them out for some Monroes, but I wound up trading up for my Altitude.

Re: Newbie question here about SRT8 springs

Sounds like staying stock may be a better idea for me for now. I may be selling the boat after this summer so maybe that will be the time to lower her down a bit. Thanks for the input!
