The Synergy Long Arm Kit is designed to improve your trucks suspension geometry while off-roading. Shorter control arm angles are hard on a vehicle’s suspension components which leads to poor vehicle handling, limited suspension travel and an overall bumpy ride as the shocks produce a choppy movement as you drive. By using the Synergy long arm kit an better angle is achieved, which offers more range of motion and doesn’t put undue stress on the truck’s suspension components.

    • 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
