74 Weld Billet Upper Control Arms 4Runner / GX / FJ (Ball Joint)
SKU: 74W-UCA-4R-FJ
When you lift your factory suspension several issues need to be addressed. As a consequence of the lift, the vehicle loses caster and your arm angles change. We solve this problem by adding back the caster you lose from the lift. We also reposition the pivot angles reducing stress on the joints and allowing you to gain droop. The increased castor allows for proper alignment and improved handling. We run a high-quality MOOG ball joint for long lasting durability. For the inner pivots we use durable urethane bushings with grease fittings for easy servicing. These arms are also fully machined on state of the art 5 Axis equipment allowing us to put the ball joints at the proper angle to maximize travel. The arms come preassembled and include detailed instructions for easy installation.
Applications:
2003-2022 Toyota 4Runner 2WD / 4WD
2007-2014 Toyota FJ Cruiser 2WD / 4WD
2003-2009 Lexus GX470 4WD
2010-2022 Lexus GX460 4WD
Wheel Travel / Lift
The upper control arms must be paired with OEM replacement coil overs to lift the vehicle. They offer an additional 1” of down 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.
*Some King OEM replacement coil overs have short reservoir hoses that come in contact with aftermarket upper control arms. This can be solved by installing longer reservoir hoses or adjusting the reservoir to allow for more slack in the hose
Tire Info
The upper control arms will allow for 33” tires but the front section of the cab mount may need to be cut to avoid tire rubbing while turning. In addition the front bumper may require trimming for proper tire clearance.
