Icon 19-23 Ford Ranger Billet Upper Control Arm Delta Joint Kit (Steel Knucle Only)

These Upper Control Arms Feature Icon'S Patented Delta Joint. The Delta Joint Is A Heavy-Duty High Angle Ball Joint That Combines The Durability Of A Ball Joint With The Performance Characteristics Of A Traditional Uniball. While The Industry Standard Uniball Does A Great Job Of Allowing The Control Arms Of A Vehicle To Articulate With Little Bind, They Do Have An Inherent Weakness That Leaves More To Be Desired When Used In A Daily Driven Application - Exposure To The Elements. The Delta Joint Features A Zinc Plated Housing Providing The First Layer Of Corrosion Resistance, While A Tough Grease Seal Keeps Potentially Harmful Elements Out Of The Inner Workings Of The Joint. Metal On Metal Construction And A Greaseable Design Increase The Longevity Of The Delta Joint While At The Same Time Allowing For Noise-Free Operation. What Makes The Delta Joint Unique Is That It Brings The Best Of Both Worlds To Icon Upper Control Arms With Features That Make It More Robust Than A Uniball, And At The Same Time Capable Of Greater Angularity Than A Typical Ball Joint.
