coil overs in factory front suspension ride tech ???

I was on ride tech website coil overs or air bags they just show a tubular upper control arm no lower in the full vehicle kit but no single front kit for bags or coil overs. rms has the whole k member does anyone make a kit using the factory control arms? how do they air bag the car ? like a 69 charger. does ride tech have a k member too ?

ride tech takes place in the same areas your shocks go

I was wondering if that's how they did it. Thanks
