We have seen issues as well with the RC upper controls. With the larger lifts they will hit the coil bucket and on some of the bracket lifts they do not allow for enough alignment since they are a "fixed" arm and have no adjustment. All the adjustment must be made with the lower control arm alignment cams.
We offer two different style arms to solve this issues. The first is our bushing/ heavy duty Moog ball joint upper control arm. This arm will eliminate the coil bucket contact with lifts and put the vehicle back within the factory alignment specs when lifting the vehicle. They are also completely sealed with grease fitting to keep maintenance as low as possible. These are also a "fixed" arm and do not have any adjustment. This is normally fine but we sometimes see with the larger bracket lifts that additional alignment is needed.
For these applications where additional alignment is needed we offer our hiem/ uniball style upper control arms. These have adjustment in the upper arm by threading the heims in or out to adjust alignment further than just the lower alignment cams.
More info on each style upper control arm can be found on the links below to our website.

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 UCA’s. We solved these problems by designing our arms with increased castor and re-positioned pivot angles reducing stress on the joints. The increased castor allows for proper alignment and improved handling. We have also replaced the weak factory ball joints with 1” stainless steel uniballs for maximum strength along with increased articulation. For the inner pivots we used heavy duty FK heims for additional adjustability in the arm. 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.

After seeing the issues with other bushing UCAs we decided to develop a competitively priced and functional UCA. These UCAs feature polyurethane bushings and heavy duty Moog ball joints. For proper fitment our polyurethane bushings are custom machined to clear the rounded corners in the pocket. This will help prevent noise and extend the lifespan of the bushings. The outer bushing sleeves are made from 2.25" .250 wall tubing and gusseted for additional strength. They include zerk fittings allowing you to service them. The Moog ball joints are completely sealed making them ideal for harsh weather conditions. Most importantly our UCAs have increased castor and additional clearance for lifted or extended travel applications. The increased castor is needed to keep the vehicle within alignment specs when raising the ride height. The arms come fully assembled and include detailed instructions making installation quick and easy.
