Description

The ISR Performance Pro Series Rear Upper Control Arms are designed to enhance the suspension system of the S13 and S14 Nissan 240sx. As an upgraded version of classic adjustable rear upper control arms, these Pro Series components offer improved durability and performance. Key improvements in the Pro Series include the use of larger Japanese spherical rod bearings, which provide smoother articulation and increased strength. Integrated dust boots within the misalignment spacers are incorporated to shield the bearings from dirt and debris, contributing to a longer service life.
