Prothane 4-1118-BL Front Stabilizer Bar Bushing Kit Black 20mm

The Prothane 4-1118-BL is a front stabilizer bar bushing kit featuring 20mm black polyurethane bushings designed to replace the soft, flexible OEM rubber units on your sway bar (also known as an anti-roll bar). Upgrading to polyurethane significantly improves the effectiveness of your existing stabilizer bar, helping reduce body roll, improve cornering traction, and sharpen overall handling response.

Key Features:

• Made from firm, durable polyurethane — resists compression and flex far better than stock rubber
• Grooved bore design retains Prothane's super grease for smooth, quiet, squeak-free operation
• Fits 20mm diameter front stabilizer bars
• Black finish for a clean underhood appearance
• Compatible with OE sway bars as well as larger-diameter high-performance aftermarket bars
• Backed by Prothane's lifetime warranty
• Made in the USA

Worn or softened rubber sway bar bushings allow the bar to shift and flex under load, leading to increased body roll, loose steering feel, and potential clunking noises. The Prothane 4-1118-BL eliminates this slop with a precision-fit polyurethane bushing that holds the bar firmly in place — delivering suspension performance comparable to installing a larger-diameter sway bar at a fraction of the cost.
