03-13 Dodge Ram 1500-3500 Synergy Front Upper Control Long Arms

A long arm suspension upgrade involves using longer control arms that mount further back on the vehicle in order to reduce suspension angles and bring the truck closer to the stock geometry. The Synergy Front Upper Control Long Arms are adjustable to allow for caster correction and re-centering of the front axle housing for oversize tires and increased ride heights. Our Double Adjuster Assembly allows adjustment of control arm length without removing them from the vehicle and uses a pinch bolt instead of jam nut for ease of use and reliability. Maintenance Free Dual Durometer Bushings are used at both ends for uncompromised articulation and isolation of Noise, Vibration, and Harshness. When paired with the Synergy Long Arm Brackets (8581) and and Synergy Front lower Long Arms (8583-04) you can guarantee an unmatched ride quality and off road capability.
