This kit includes the left and right replacement radius rod bushings where mounted to the chassis. This arm is also referred to as the 'TC' rod, compression arm, strut rod, and even the 'banana arm'. SuperPro offers a robust one-piece bushing kit with a metal shell to replace the failure-prone OEM bushings. Nissan sells the OEM replacement only as a complete arm with the bushing pre-installed costing hundreds of dollars and offering only the same failure-prone OEM piece again. SuperPro has engineered a more complete replacement that enhances road feel and precision as well as offering a longer service life and more consistent alignment.
