Had these installed today. Took about 2.5 hours. Mind you, the blizzaks are almost 29" tall, so the gap will be a little more with my street tire setup and even more with a drag setup in the rear. These are a "close" spring rate to the Dodge Demon springs designed to be an improvement over what the cars come with. The charger has a softer spring rate than the challenger, so my improvements might not be as dramatic. They are supposed to help the 60' and improve weight transfer. Time will tell when the weather gets better and I can get a good whack out of the hole. It seems the actual OEM Demon springs make the car sit significantly higher in the rear. I'm ok with how this version turned out. I'll post more pictures when I get the car on its "normal" tires.

These were $299

Labor was $350

I ordered the same thing for my scat pack challenger they come in today. I’m also excited to see if they can improve my 60’s any also. Hopefully I will have some results this weekend. Also where did you get them installed for 350? 2 dealership told me 450 & 525 plus the 60 bucks for alignment

Looks good. I have the OEM Demon springs but haven't installed them yet. I hear they make the car sit taller at first, but that they settle over time. Extra weight from the Hellcat might speed that along.
The OEM demon springs do sit different compared to these. The rear end will sit much higher with OEM Demon springs from what I've seen in photos.

My measurements didn't change in the rear, but the front is about 1" taller.

Couple things...
You wash your car in the winter? .... lol

Also, wouldn't the shock be a better piece to upgrade than the spring if you're trying to improve 60'? Ideally, wouldn't you want the shock/strut/spring from the Demon as a combination?
I don't know, that is a question... just thought the shock played a larger role in 60' than the springs.

Yes.....I'm pretty sure I have the cleanest DD around :)

Yea, if I could get the shocks and the capability to control them like the demon for sure. This is just a small piece in the puzzle. One member on here has them on his car and yanked the front wheel on his charger, so they are helping with weight transfer in some capacity.

Hmm been thinking about switching from my lowered KW HAS springs to these. These are the first pictures I've seen for the ride height. I bought the car lowered, I know it looks good but I cringe every time I scrape my exhaust or front lip.

I wonder if you could cut the front spring slightly and lose the inch and still get the desired results? I'd like to switch to the demon springs but like the OEM stance on the Redeye.

Edit: I sent them a message on IG asking this question. I'll report back if they respond.

I just bought a set of them myself for my Redeye. Not a big fan of of raising the ride height, but I hear it's not as bad as the OEM Demon springs. Seems like a pretty cheap way to get better and more consistent 60fts. Unfortunately I won't be able to test mine anytime soon, winter doesn't seem to want to go away!

Winter is a great time to collect new parts lol.

I'll say. I'm thinking the back sits just a bit lower. Not much, and the front sits just a bit higher, maybe .5"

I put mine on yesterday and the back is ok but dang the front is high on my car. Probably 1.5 inches higher :eek: I’m hoping they will settle some and come down. The ride is smoother tho she rides even better now than with stock springs but my scat pack don’t have the adjustable suspension that the Hellcat’s have.
