About this lower caster arm
The SuperPro SPF1831AK front lower caster arm bush kit (offset) is engineered with strength and durability in mind, a complete, premium upgrade. Compared with rubber, the polyurethane gives higher quality, quieter and longer lasting bushings. SuperPro says its polyurethane bushings provide corrected or maintained steering geometry, better handling, increased safety and improved tyre wear.
