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 also replaced the weak factory ball joints with 1” stainless steel uniballs for maximum strength and increased articulation. For the inner pivots we use durable urethane bushings with grease fittings for easy servicing. To mount the arms to the spindle we include high grade 17-4 stainless steel misalignment spacers and military grade F911 hardware. 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: Allows for 0-3” of lift Track Width: Stock Maximum Backspacing: 4.75” Minimum Rim Size: 17” Coil over Shock Size: Factory or OEM replacement coilovers Wheel Travel / Lift The upper control arms must be paired with OEM replacement coil overs to lift the vehicle. These arms are compatible with King, Fox, Bilstein, ADS and Icon coil overs. Do not install these upper control arms with coil spacers that over articulate the suspension. Tire Info The upper control arms allow for 33” tires but for proper tire clearance modifications to the wheel well and bumper may need to be made.  What's Included Boxed plate upper control arms Urethane bushings Grease fittings 1” Probearing uniballs 17-4 stainless steel misalignment spacers Military grade F911 hardware Zinc plated inner bushing sleeves Durable black powder coat Dirt King sticker pack Installation instructions   Features CAD designed  Boxed plate construction 4130 chromoly uniball cups Brushed stainless steel logo plates Preassembled for fast installation Grease fittings for easy servicing Zinc plated components for corrosion resistance Professionally MIG welded Proudly made in the USA   Compatibility 2015-2022 Chevy Colorado 2WD / 4WD 2015-2022 GMC Canyon 2WD / 4WD *Will not work on  ZR2 models *This product is designed to pair with OEM and Dirt King parts.
