Unlock the full potential of your Ram's suspension with the Synergy 2003-2013 Dodge Ram 1500 / 2500 / 3500 Long Arm Upgrade Kit. Heavy duty frame brackets and USA made adjustable long arms bring your lifted Ram's suspension geometry closer to stock by moving the control arm mounting points further back — improving ride quality, stability, and suspension performance both on and off road. Adjustable lower control arms are a critical component for any lifted vehicle to correct caster angle and center the axle after a suspension upgrade. Delivering the perfect balance of adjustability, strength, and refinement for lifted and oversized-tire setups and equipped with Synergy’s innovative Double Adjuster Assembly, you can fine-tune arm length and caster angle without removing the arms from the vehicle. Maintenance-Free Dual Durometer Bushings (DDB) at both ends provide the ideal blend of articulation and isolation, ensuring a quiet, smooth ride with exceptional flex and durability.
Pro Tip: Pair these control arms with our Heavy Duty Adjustable Front Track Bar part number 8550-11 to fully recenter your axle and achieve the best alignment possible!

Notes:
- Engineered to fit trucks with 0" - 6" of lift height
- Upgrading to long arms requires cutting, grinding, and drilling as well as removal of the stock control arm brackets at the frame; We recommend all cutting / grinding / welding be done by an experienced welder / fabricator
- 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
- Please note: Tire dimensions and sizing vary from manufacturer to manufacturer
- While this is a bolt on kit, welding the brackets after installation is a clean, reliable method
- 8565 Cam Bolt Eliminators recommended for increased strength and extended bushing life
- Additional bushing sleeves are included for 2010 - 2013 models with larger bolt diameters
