Prothane 13-1105-BL Front Sway Bar Bushing Kit 20mm Black Polyurethane

The Prothane 13-1105-BL is a front stabilizer bar bushing kit featuring firm polyurethane construction designed to replace soft, worn OEM rubber bushings. Upgrading to these polyurethane bushings restores proper sway bar function, reduces body roll, and improves cornering response and traction.

Standard rubber bushings flex and deform under load, allowing the stabilizer bar to shift and reducing its effectiveness. Prothane's polyurethane material holds its shape under stress, keeping the sway bar firmly in position and maximizing the anti-roll bar's contribution to handling. The result is sharper turn-in, better chassis control, and reduced body roll without the need for a more expensive large-diameter aftermarket sway bar.

Key Features:

• Fits 20mm front stabilizer bar
• High-durometer polyurethane construction — firmer and more durable than OEM rubber
• Grooved bore design retains Prothane super grease for quiet, squeak-free operation
• Black finish (BL suffix)
• Direct OEM replacement — no modifications required
• Backed by Prothane's lifetime warranty
• Made in the USA

This kit is also compatible with larger-diameter high-performance aftermarket sway bars of the appropriate size. Prothane super grease should be used during installation to ensure long-lasting, noise-free performance.
