Product FAQs
Is this a rubber or spherical bearing replacement?
This part uses a low-friction spherical bearing in place of a compliant rubber interface. Match the named suspension location and part number; trailing-arm, knuckle and inner-arm bushings are different components.
Does a monoball bushing kit add camber or toe adjustment?
This is a spherical-bearing replacement for the named mounting position. Its purpose is to reduce compliance and allow articulation; it is not an adjustable camber or toe arm. Use the correct link or arm when alignment adjustment is also needed.
What should a street-car owner know about NVH?
Replacing compliant factory mounts or bushings with a more rigid connection can transmit more road noise or impacts. SPL identifies an NVH tradeoff for this part; consider it when choosing components for a daily-driven car.
