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 delrin 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 grade 8 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.

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.

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.
