Prothane 16-1104 Rear Sway Bar Bushings for WRX STI, 20mm Bar, Red Polyurethane

Upgrade the rear suspension of your WRX STI with Prothane 16-1104 rear sway bar bushings. Designed for vehicles equipped with a 20 mm rear sway bar, these bushings provide a durable polyurethane replacement for worn or deteriorated original components. The red polyurethane construction helps support consistent sway bar positioning and reliable suspension performance during everyday driving or spirited use.
Prothane 16-1104 bushings are non-greasable and designed for a straightforward replacement installation. Their precision-fit design helps reduce excess movement around the rear sway bar, supporting improved handling response and more controlled suspension operation. The polyurethane material offers increased resistance to common wear, compression, and environmental exposure compared with many conventional rubber bushings.
This complete pair is intended for the rear sway bar and is suitable for drivers seeking a durable suspension upgrade without changing the vehicle’s overall suspension design. Confirm that your vehicle uses a 20 mm rear sway bar before ordering. The red finish provides easy identification while adding a clean performance-oriented appearance to the undercarriage.
