Are you launching your Scatpack or Hellcat hard? Want a nice stance, and to eliminate the sloppy arms from the mix? We have you covered. The stock arms are the same from V6 to Hellcat, they don’t cut it and often fail, and flex a ton, the differentials rock and often fail and shatter, and the subframe walks causing drive shaft and axle failure.

Our package includes the following:

-Choice of Eibach Pro-kit, or Drag-launch springs
-AAD Suspension Arm Drag Pack - This kit consist of track proven rear upper adjustable control arms (RUCA and RUTA), rear lower trailing arms featuring Spheriflex bushing (RLTA), and very popular rear adjustable toe links.
-BMR Rear cradle “ Subframe” lockout kit – (removes slop from the soft factory bushings and keeps the cradle planted)
-Per4mance Differential Brace- (keeps that diff planted, these differentials can shatter on a hard launch. The standard and DIRS both combat the issue but the standard allows for noise to resonate into the chassis)
-Optional AAD front upper Control Arms Full billet aluminum, fully-adjustable Front Upper Control Arms for your 2WD Charger, Challenger, Magnum, 300, Hellcat, etc. These Arms use our unique tab-lock system to facilitate easy, on-vehicle Camber adjustment so that when you lower your ride, you can get your Front Camber back in spec. We also use more rigid inboard bushings (90A polyurethane) or our new Patent Pending Spheriflex teflon impregnated Delrin spherical bushings to reduce or eliminate the slop in the OEM parts.

Removal of subframe not required, it can be lowered on a lift, we have installed many of these kits without total subframe removal. Professional installation recommended.

Color note - Springs do not have a color choice. Pro-kit
are red, and drag-launch are white. Standard differential braces come in Red or black, D.I.R.S. are only available in black. AAD Arms are available in Red or Black and sometimes special edition colors such as Blue or America Edition. Please contact us to inquire about special color options.
