Tubular Upper Control Arms with 3-Degree Caster Correction

The Dobinsons UCA59-002K Tubular Upper Control Arms are engineered to enhance the performance and alignment of vehicles equipped with lifted suspensions. Specifically designed for applications lifted 1.5 inches or more, these control arms incorporate a fixed 3-degree caster correction, eliminating the need for additional adjustments and ensuring proper wheel alignment after lifting. Constructed from High Strength Low Alloy (HSLA) steel with a robust 5mm (0.2″) wall thickness, these arms offer exceptional durability and are finished with a protective powder coating. They feature pre-set with a 3-degree caster angle to optimize alignment for lifted vehicles, removing the complexity of further adjustments. Maintenance-free operation is a key benefit, as these arms are equipped with replaceable Japanese-made Sankei 555 ball joints and OE-style rubber frame bushings. Both components are fully sealed for a long, maintenance-free lifespan, and the kit includes everything needed for installation: left and right control arms, pre-installed bushings, ball joints, and necessary washers. These control arms are an ideal upgrade for off-road enthusiasts and drivers seeking improved handling and alignment in lifted vehicles. They are compatible with 4th Gen 4Runners (2003-2009), 5th Gen 4Runners (2010-2018), Lexus GX470 (2003-2009), Lexus GX460 (2010-2018), and all generations of Toyota FJ Cruiser. It is important to note that these control arms are intended for vehicles lifted 1.5 inches or more; installation on vehicles with less lift may prevent a proper wheel alignment.
