Description

Part #: 78550DJ

Take the performance of your 2001-2010 GM HD truck to new levels with the ICON Vehicle Dynamics Delta Joint tubular upper control arm kit. All ICON tubular upper control arms are constructed from CNC bent 1026 DOM steel tubing and then powder coated to a semi-gloss black finish for maximum strength and corrosion resistance.ICON upper control arms are engineered with built-in caster correction for optimal alignment specifications and confidence inspiring handling. A main benefit of ICON upper control arms is the increased wheel travel (nearly 50 Percent) when paired with our 2.0 or 2.5 series shock absorbers, this translates into superior performance and ride quality for your 2001-2010 GM HD.Features and Benefits: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 greasable 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.ICON Delta Joint1026 DOM Steel ConstructionCNC Bent TubingServiceable Dual Stage BushingsCNC Machined Bushing Housings and SleevesBuilt-In Caster CorrectionBlack Semi-Gloss Powder Coat FinishDetailsColor: BlackMaterial: Dom SteelFinish: PowdercoatedAdjustable: NoBall Joint Included: YesBall Joint Mounting Type: Press InBall Joint Stud Type: ThreadedBushing Color: BlackBushing Material: PolyurethaneBushings Included: YesControl Arm Color: BlackControl Arm Construction: TubularControl Arm Material: SteelGrade Type: PerformanceGrease Fitting Included: YesMounting Hardware Included: YesOem Wheels & Tires Fitment: YesPre Greased: NoRecommended Aftermarket Tires: 33 Inch X 11.50 Inch (Larger Tires May Fit But Fender Trimming And Modifications Will Be Required)Recommended Aftermarket Wheels: Icon Alloys - 20x9 Inch W/ 5.5 Inch Backspace / 12mm Offset, Icon Alloys - 18x9 Inch W/ 5.5 Inch Backspace / 12mm Offset, Icon Alloys - 17x8.5 Inch W/ 5.25 Inch Backspace / 13mm OffsetService Parts: 614522 - 78550/78550Dj Bushing And Sleeve Kit, 614519 - Delta Joint Install Press Adapter TubeSuspension Grade Type: PerformanceAdd On Part: 191013 - Nipple Greasing Adapter Kit, 191011 - Tubular UCA Billet Cap Set
