Engineered and manufactured in the USA, the 3" Dodge Long Arm System is designed for increased performance, stability, and ride quality both on and off road. The massive 2" diameter Front Lower Long Arms offer best in class ground clearance and allow the use of larger tires without rubbing. No bump stop spacers required. Long arms and track bar feature zero maintenance Dual Durometer Bushings (DDB) for increased longevity and vibration dampening. This system will lift the truck 3.0" and accommodate up to 37" tall tires.

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

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

Recommended Components: 

  • 8525-01 - Synergy HD Steering Kit
  • FOX-982-24-941 - Fox Steering Stabilizer
  • 8558-04/8559-04 - Synergy Steering Box Brace

Notes:

  • Due to the additional weight of megacab truck configurations, we recommend all gas megacab trucks use Heavy Duty (HD) front coil springs instead of Light Duty (LD) front coil springs. LD front coil springs will give less lift than advertised
  • Upgrading to long arms requires removal of the stock control arm brackets at the frame
