It won't ride any differently. If you look up most coilover and air ride suspension, it will be labled for the Charger/Challenger because those are the "performance models" as Dodge is FCA's "performance" brand.
That said, I had Charger coilovers on my 300 and my sway bars were from a Challenger SRT8.
LX is our chassis code...it's the chassis code for the Chargers, Magnums, and 300's. The Challenger is a few inches shorter (4 I believe) so it's LY. But, under the skin, our cars are virtually the same. that's why all of us are on the same forum. You can swap 300/Magnum/Charger front clips, suspension, exhaust, motors, transmissions, brakes, all within reason (i.e. 5.7 <-> 5.7 or 3.5 <--> 3.5 etc). So, the springs will fit in the spring perches because the springs perches are identical. You honestly, probably won't notice the difference in drop. The stock height difference is less than an inch IIRC.
But, in general, unless you know exactly what you're looking for, if you're searching for something related to performance, and can't find it, look it up for the Charger. It's the same thing.
