Synergy Jeep JL Adjustable Front Upper Control Arms are a Heavy Duty upgrade for the stock fixed length JL control arms. They are adjustable to allow for correcting pinion angle 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 (NVH).
