SPC Front Upper Control Arms

The SPC 72270 is a pair of adjustable upper control arms, designed to enhance the performance and alignment capabilities of select Lexus GS and SC models. These arms provide a versatile range of adjustments, allowing for ±1 degree of caster change and ±2.0 degrees of camber change. This precise adjustability is crucial for optimizing suspension geometry, whether for performance driving, correcting alignment issues after ride height adjustments, or minimizing tire wear. The construction of the 72270 control arms features a tubular welded design, which significantly reduces weight while simultaneously increasing overall strength and durability. These arms are crafted using aircraft-quality materials and come equipped with OE-style bushings, contributing to reduced vibrations and an improved comfort level during operation. Sold as a pair, these upper control arms are a direct replacement for the OE front upper control arms on compatible Lexus vehicles, including the GS300 (1993-2005), GS400 (1998-2000), GS430 (2001-2005), and SC430 (2002-2010). Proper installation is critical; it should only be performed by individuals possessing the necessary skills, training, and tools to ensure the job is completed correctly and safely. Incorrect installation can lead to personal injury, damage to the vehicle, or a loss of vehicle control.
