2003-2013 Cummins Long Arm Upgrade Kit (8580-04)

Description

Fits

Note: 2013 Dodge Ram 3500's were a split year for production. If your truck has radius arms use Dodge Ram 2014+ pages.

The Synergy 8580-04 Long Arm Kit is designed to improve your truck's 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 a better angle is achieved, which offers more range of motion and doesn’t put undue stress on the truck’s suspension components.

Notes

• To prevent front tires from rubbing the control arms at full steering lock, we recommend the following wheel/tire combinations:
  • Most* 37" tires - wheels must have no more than 4.5" of backspacing
  • Most* 40" tires - wheels must have no more than 3.75" 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
