Let me make this easy for those looking to lower their Challenger.

Stack’s spring design reflects our ability to develop a quality spring, increasing handling capability, giving your Challenger a very clean lowered stance, all while retaining excellent ride quality. These springs feature increased spring rates for upgraded handling capabilities and superior ride quality.

Plain and simple the product is as described. Ryan designs, builds and stands by his products and he scores again with these lowering springs. You can click on the link at the bottom to read about the specs but here are some of the features:

Front Drop: 1.4"
Rear Drop: 1.3"
Front Rate: 310 lbs/in
Rear Rate: 725 lbs/in
Limited lifetime warranty
Should not require alignment – mine did not
These lowering springs are designed to work with OEM shocks only.

I’m modding my Challenger from the ground up for the most part. The lowering springs are a great addition to my other suspension mods. I also have the front and rear SP Chubby Pro sways and the front SP Stiffie STB. When the time is right I’ll continue the suspension mods with the rear STB and 3rd Member X-Brace.

Nice right? It gets better for those with a budget and it is something that you won’t see in the SP website or on the forums, yet. I don’t know when but soon Ryan is going to be doing a group buy for these lowering springs. If you call him now you can get the group buy price of $264.99 and get your order in early. From my own experience and from what MBPhotos said about these lowering springs, I have a feeling they will be in demand.

Speaking of MB I was pleasantly surprised to see him when I pulled into SP Tuesday morning and as always with camera in hand. He was there getting the lowering springs as an early surprise birthday present for his Dad. You really have to admire the parenting skills there! We were like two kids in a candy store checking out all the sweet rides at SP that day. We saw some fellow SCC members Challengers and a BA Torred R/T with black defender stripes.

Tim worked on my R/T like it was his own. I have no problem handing my keys to him because I know from previous experiences that my Challenger is the best hands. Thanks again Tim!

So for $264.99 and a couple hundred bucks for labor I got increased handling, nice drops in height ride height with No sacrifice in comfort. Damn!

I highly reccomend the SP lowering springs and you can't beat that price! It has been a few days since the install and I still can't get the smile off my face!

Great write up Jeff! And I can honestly second everything said. It's an amazing upgrade for the price and highly recommend it! And it was a great surprise to see you there too, when I was waiting for Ryan to finish his morning duties he said he was doing your car that day too and the same install, I was pleasantly surprised to see you come while I was there! I figured you would be there in the evening.

The whole kids in a candy store hit it on the head. I couldn't stop thinking to myself "ooo I want this, and this and that and one of those and one of these and that!" hahahahaha

Coming soon for us will be: rear stiffy STB (to go with our front we just installed), x-brace and chubby pros!

Pretty stoked! Can't wait!

And my dad absolutely loved it, he came home that evening and we just stood in the window staring at the car for a few minutes with big grins on our faces

Congratulations to both of you on the new look/feel.

Yet again another reason why Ryan is at the top of the "heap".
Way to go Ryan and crew.

Got my car back today! One of my goodies was the Chromoly 3rd Member X-Brace....WOW!

Even with my SMS suspension...the X-Brace really tightened up the front end, killed all the slop, I LOVE it.
