Features:

  • Dual Durometer Bushings (DDB) feature a maintenance free, grease less design
  • Housings are forged from high strength 1045 steel and treated for corrosion resistance
  • Control arm bushings are self centering with 30 degrees of misalignment
  • Outer “soft” durometer acts as bushing cushion and flex material
  • Inner “hard” durometer lining acts as the bearing surface to allow free floating inner sleeve to rotate.
  • Provides for a maintenance free “zero bind” bushing
  • Internal bushing ring separates inner and outer materials to prevent inner sleeve gaping at extreme flex
  • Direct replacement available for Synergy products using a Johnny Joint or rod end
  • Available complete with bushing installed

Notes: 

  • For 94-02 Ram track bar applications, the track bar conversion bracket part number 8554-02 is required to be used

Synergy Adjustable Front Track Bar 2-6″ Lift for 1997-2006 Jeep TJ/LJ, 1984-2001 XJ, 1993-1998 ZJ, 1986-1992 MJ

A heavy duty, adjustable, front track bar designed as a factory style replacement for TJ/LJ, XJ, ZJ, and MJ applications. It directly mounts to the factory tapered track bar mount on the frame but requires the axle mount to be drilled to 9/16″ for added strength. A recommended weld-on gusset is included for the axle side mount for reinforcement. The track bar offers improved rigidity and allows centering of the front axle when running a suspension lift. Fits 1-4″ lifts.

Fitments:

  • 1997-2006 Jeep Wrangler (TJ)
  • 2004-2006 Jeep Wrangler (LJ)
  • 1987-2001 Jeep Cherokee (XJ)
  • 1993-1998 Jeep Grand Cherokee (ZJ)
  • 1987-1992 Jeep Comanche (MJ)

Features:

  • Synergy Jeep TJ/LJ, XJ, ZJ, MJ Adjustable Front Track Bar
  • Features Synergy Dual Durometer Bushings (DDB) with Teflon® bearing surface for a maintenance free design focusing on performance, flex, longevity, and ride quality
  • Bolts into factory tapered track bar bracket on the frame
  • Requires axle mount to be drilled to 9/16″
  • Optional welding (required if desired to install axle gusset)
  • Made from 1-3/8″ 1018 CR Solid Round Bar stock
  • Includes new Grade 8 mounting bolts and hardware
  • Synergy double adjuster sleeve & pinch bolt assembly allows for adjustment of track bar length without removal from vehicle
  • Suspension components feature an abrasion-resistant powder coat finish for maximum durability and corrosion resistance
  • Fits 1-4″ Lifts

Notes:

  • Factory style replacement track bar for 1-4″ of lift
  • 2.0″ to 3.0″ bump stop spacers will be required if the axle is pushed forward slightly from stock and an aftermarket diff cover is used. The larger diameter of the Synergy track bar and tie rod end will interfere with the diff cover if no bump stop spacer is used. We recommend cycling the suspension to full compression with the track bar installed to ensure no interference is occurring.
  • Approximate collapsed length = 31″
  • Approximate extended length = 32.4″
  • Replacement bushing is 4323-01, replacement tie rod end is 4135-L

Installation Notes:

  • Requires drilling. Sanding and Welding are optional

Synergy MFG Suspension Systems use a synergistic approach, meaning the combined effect of the components is greater than the sum of the individual parts. The overall performance of the system is the most important factor when we are designing components to work together. Synergy MFG Suspension Systems are complete systems for your vehicle and include all necessary components for the lift height and performance advertised.

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.

Notes:

  • To prevent front tires from rubbing the control arms at full steering lock, we recommend the following wheel/tire combinations: * Same size tires will dimensionally vary from manufacturer to manufacturer.
    • 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.
  • Due to the additional weight of mega-cab truck configurations, we recommend all gas mega-cab 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
