Boxed Upper Control Arms

Description There are multiple issues when lifting your vehicle with stock upper control arms. Both the geometry and strength are compromised due to over articulating the stock arms. We solved these problems by designing our upper control arms with increased castor and repositioned pivot angles reducing stress on the joints. The increased castor allows for proper alignment and improved handling. We upgraded the ball joints to heavy duty Moog joints for maximum strength and increased articulation. For the inner pivots we use durable delrin bushings with grease fittings for easy servicing. All of the components on our upper control arms are rebuild-able or replaceable to make this product last a lifetime. The arms come preassembled and include detailed instructions for easy installation.  Specifications Amount of Lift: 0-3” Track Width: Stock Maximum Backspacing: 4.75” Minimum Rim Size: 17” Compatible with Sway Bar: Yes Coil Over Shock Size: Stock or OEM replacement shocks Wheel Travel / Lift The Dirt King upper control arms must be paired with aftermarket coilover shocks to lift the vehicle. The Dirt King arms offer maximum down travel compared to the stock upper control arms. These arms are compatible with Dirt King, King, Fox, Bilstein, ADS and Icon coilovers. Do not install these upper control arms with coil spacers paired with extended length aftermarket shocks. Tire Info The upper control arms allow for 35” tires but for proper tire clearance modifications to the wheel well and bumper may need to be made. Magnetic Ride Control Installing this suspension on vehicles equipped with magnetic ride control require modifications to the ride control sensors. If you choose to replace the magnetic ride control shocks with coil overs it will cause an indication light to appear on the gauge cluster.  What's Included Boxed plate upper control arms Delrin bushings Grease fittings Moog ball joints Zinc plated inner bushing sleeves Durable black powder coat Dirt King sticker pack Installation instructions   Features CAD designed  Boxed plate construction Brushed stainless steel logo plates Preassembled for fast installation Grease fitting ports for easy servicing Zinc plated components for corrosion resistance Professionally MIG welded Proudly made in the USA   Compatibility 2007-2020 Chevy Tahoe 2WD / 4WD 2007-2020 GMC Yukon 2WD / 4WD *This product is designed to pair with OEM and Dirt King parts.
