The upgrade kit is designed for customers who already have a Synergy Pre-Run kit or Synergy Starter System that want to upgrade to a Long Arm kit for improved on and off-road performance

  • The Synergy Long Arm kit was designed and engineered from the ground up using a synergistic approach to maximize the Dodge 4x4 truck's on & off road performance

  • Long arm kit was designed using OEM CAD files for a perfect fitment and enhanced vehicle drivability

  • Kit can be installed on anything from a completely stock truck to a 6" lift and 12" stroke 3.0" diameter shocks. 

  • Suspension components feature a 2 stage powder coat finish for maximum durability

  • Synergy double adjuster sleeve & pinch bolt assembly allows for easy adjustment of control arms without removal from vehicle to provide for easy, perfectly adjusted alignments

  • 8583-04 - 03-13 Dodge Front Lower Control Arms (Pair)

Wheel/Tire Fitment Notes:

To prevent front tires from rubbing the control arms at full steering lock, we recommend the following wheel/tire combinations:

  • Most* 37 inch tires - wheels must have no more than 4.5 inches of backspacing
  • Most* 40 inch tires - wheels must have no more than 3.75 inches of backspacing

* Same size tires will dimensionally vary from manufacturer to manufacturer.

  • 8565 Cam Bolt Eliminators recommended for increased strength and extended bushing life
  • Upgrading to long arms requires removal of the stock control arm brackets at the frame
