When you lift a truck or add aftermarket coilover shocks to the front of your truck, you are changing the geometry of many front-end components. There’s a lot of factors to consider when doing this, as not only can it affect your ride quality if not done properly, but it can be a detrimental to your safety.
One of the most recommended upgrades when adding an aftermarket coilover is a set of Upper Control Arms. Dirt King Fabrication has designed their Boxed Upper Control Arms with increased castor and repositioned pivot angles. The increased castor allows for proper alignment and improved handling, while the pivot angles reduce stress on the joints and increases your safety. To further this product with maximum strength and increased articulation, Dirt King has replaced the weak factory ball joints with 1” stainless steel uniballs. For the inner pivots Dirt King uses durable Delrin bushings with grease fittings. This provides consumers with a very simple way of servicing when needed. To mount the arms to the spindle, Dirt King includes high-grade 17-4 stainless steel misalignment spacers and grade 8 hardware. To provide consumers with a product that can last a lifetime, Dirt King designed all components on the Upper Control Arms to be rebuildable if needed. Your Boxed Upper Control Arms come preassembled and include detailed instructions to ensure a hassle-free installation.

*Wheel Travel / Lift*
The upper control arms must be paired with OEM replacement coil overs to lift the vehicle. They offer an additional 2” of travel compared to the stock upper control arms. 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.
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.
