Subaru WRX Suspension Knuckle Bushing Kit - Rear - SPL Parts - Solid FK Spherical Bushing (2015-2027). Replace the OEM rubber rear knuckle bushings with PTFE-lined spherical bearings for precise, consistent handling.

Built to remove compliance that skews alignment under hard acceleration and braking, this kit controls geometry and reduces binding by allowing smooth knuckle articulation. SPL fits the largest practical US-made FK bearing in CNC-machined 6061-T6 aluminum shells with +/- 0.001 in tolerance. This yields clearer feedback, quicker response, and reduced wheel hop in a lightweight package (0.674 lb pair; 0.337 lb/side).
