Prothane 7-1186 Front Sway Bar Bushing Kit 44mm Polyurethane

The Prothane 7-1186 is a front stabilizer bar bushing kit designed for 2WD Chevrolet Trailblazers equipped with a 44mm (1.73 inch) front sway bar. This kit replaces the factory rubber bushings with precision-molded polyurethane bushings, restoring and enhancing the effectiveness of the OEM anti-roll bar.

Worn or soft stock rubber sway bar bushings allow the stabilizer bar to shift and lose its grip on the frame, leading to increased body roll, clunking noises, and reduced cornering traction. Prothane polyurethane bushings hold the bar firmly in place, delivering tighter handling and more predictable response.

Key Features:

• Made from high-performance polyurethane — more durable than OEM rubber and resistant to road grime, oils, and weathering
• Grooved bore design retains Prothane Super Grease for smooth, quiet operation
• Firmer material prevents warping and maintains a secure grip on the sway bar over time
• Available in red or black (add suffix -BL to part number for black)
• Sold as a pair — all sway bar bushing kits include two bushings
• Includes Prothane Super Grease for proper lubrication during installation
• Backed by Prothane's lifetime warranty against defects in materials and workmanship
• Made in the USA

Upgrading to Prothane polyurethane sway bar bushings delivers a handling improvement comparable to installing a larger diameter sway bar, at a fraction of the cost. Be sure to apply the included Super Grease during installation to ensure quiet, long-lasting performance.
