Was shopping for springs for the hell cat and noticed that the Eibach part number between the scat pack and hellcat are the same. I guess Eibach made the same spring rates for both? My only question is the spring rates are increased on the hellcat from the scat pack so I guess Eibach didn't care about compensating?

Are there any springs out there that do compensate for the additional spring rate that the hell cats came with?

I had eibachs on my WB Scat and I felt like the fronts were just a tad soft so I'd hate to see what the hellcat would feel like on the same springs with the increased weight.

Thoughts ?

The WB Scats came with the stiffest stock springs https://www.hellcat.org/threads/spring-rate-info-for-hellcat-392-1320-demon-etc.237014/ and a few video reviews confirm the stiffer ratings for the WB Scat.

My guess is Eibach designed and tested the springs for the Hellcat and they also fit the Scat. I experienced this when I purchased the Hotchkis springs for my 392, designed for the Hellcat but fits on other models. Due to the front weight difference, the front springs did not settle as low as advertised for the Hellcats…advertised as 1” but I only got 3/4” on my 392.

Send Eibach an email to confirm if the springs were designed and tested using a Hellcat…my guess is yes. However, for the best handling and adjustable springs, then KW Adjustable Springs are your best option.

They made the same set since they have the same suspension. The other Charger springs will not fit the Scat Pack and Hellcat because of the bigger rear axle. I went through this while looking for drop springs for my Scat Pack. I never even used them since the springs settled so much after 12K miles. My Hellcat, which had 35K when I bought it, settled a lot, so I never needed them and sold them.

interesting. I guess I read the articles wrong. The way I read the claims was HC had higher spring rate over the scat but the articles just state its a high spring rate over same model / previous years. Makes sense now. Interesting though that the HC would have a softer spring given the increased weight on the front end. I need to reach out to Eibach and ask about the above mentions R&D.

Edit: I love forums. FB is killing them and all I get on FB pages is a bunch of nothing or even worse, trash.

FB is killing the forums? FB has killed the forums. I used to belong to a bunch of forums. The wealth, depth, and scope of knowledge shared on them was irrereplacable, sadly the younger generation and their bullshit ways believe FB is the way to go. As a result forums of all genres have paid the price. I was actually surprised when I found this one and how active it was. But if you look at the average age of hellcat owners is 50yrs old it makes sense.

"Hey all thanks for the add. Look at pictures of my car."

*Look at all the people say, "Welcome from... Look at pictures of my car."

If you deviate from that and ask actual car questions or disagree with anyone for any reason, the mods kick you out of their page.

You can see how high the WB scats sit. They sit as high as a awd challenger
Actually it is an optical illusion, I have a 2019 WBSP and my buddy has a 2019 Shaker regular body side by side they look dramatically different measuring them mine is less than a 1/4 inch higher measured in multiple locations. His car at the time had 10000 miles mine has 800.

I forgot to add where the illusion comes into play is the wheel gap, the added flares sit higher to fit the lager wheels and tires. that measurement was dramatically different by 3/4 of an inch.

Another thing is maybe the adjustable suspension has different springs? I had the base suspension, and it sat like a 4x4. Other Scats with the adjustable seemed to sit lower. I never got around to seeing if each suspension had different springs or not.

Only lower the front end, you get a little over half of the overall cg lowering effect, better downforce, spoiler gets lower to the ground, increasing downforce even more, better engine compartment evacuation and no problems with your rear half-shaft angles making them go South.

F1 cars are angled like that from front to back, and they have all the budget you could want.

I would but it just doesn't look right to me. Even though most opt for function over form I still want it to have an esthetically pleasing look even though it may sacrifice function a little bit. As far as the half shafts I've accepted that as my fait given time. I won't mind replacing a couple as time goes by. It won't be driven but a couple thousand miles a year so I might be able to prolong the life as far as time is concerned, mileage... Not so much lol

one thing I've definitely noticed is that the non WB pre 2020 chargers sit perfect no lowering needed, and that's saying something coming from me on the 30+ cars I've owned 28 of them were lowered on coils or some form of aftermarket suspension. The WBs sit too high for me but I want to retain the damper adjust ability electronically, so springs it is
