Prothane 11-42057-BL 17mm Front Sway Bar Bushing Kit Black Polyurethane

The Prothane 11-42057-BL is a black polyurethane front sway bar bushing kit designed for 17mm (0.66 in.) stabilizer bars. Upgrading from worn or soft OEM rubber bushings to Prothane's firm polyurethane construction restores and improves sway bar performance, helping reduce body roll, increase traction, and sharpen handling during cornering.

Unlike factory rubber, Prothane polyurethane maintains its shape over time and resists breakdown from road grime, moisture, and automotive fluids. The grooved bore design retains Prothane's included Super Grease, ensuring quiet, squeak-free operation throughout the life of the bushing.

Key Features:

• 17mm (0.66 in.) bore diameter — engineered for precision fit on 17mm front stabilizer bars
• Black polyurethane construction — firmer and more durable than OEM rubber bushings
• Grooved bore — retains Super Grease for quiet, long-lasting operation
• Resists degradation from oil, road grime, and weathering
• Lifetime warranty — Prothane guarantees against defects in materials and workmanship for the life of the original purchaser's vehicle
• Made in the USA

Prothane sway bar bushings maintain a secure grip on the stabilizer bar without warping or cracking, delivering handling improvements comparable to installing a larger diameter sway bar. Super Grease is included — proper lubrication during installation is essential to prevent squeaking.
