Description

SPL rear knuckle bushings replace the rubber factory knuckle bushing with a low-friction PTFE-lined spherical bearing. Replacing the OEM rubber bushing eliminates deflection under heavy acceleration and braking loads that leads to unwanted geometry changes, and prevents binding by allowing the knuckle to smoothly articulate. The reduced deflection also translates to improved driver feedback from the tire and better overall response.

  • Rear spherical knuckle bushing for select BRZ, FR-S, 86, GR86, WRX, and WRX STI applications
  • PTFE-lined spherical bearing replaces the OEM rubber bushing
  • Eliminates deflection under acceleration and braking loads
  • 6061-T6 aluminum housing, precision cut
  • Aluminum finish
