Prothane 7-1133 30mm Front Sway Bar Bushing Kit Red Polyurethane

The Prothane 7-1133 is a front stabilizer bar bushing kit engineered to replace the factory rubber bushings on your sway bar (also known as an anti-roll bar) with firm, long-lasting polyurethane. Designed for a 30mm (1.18") front sway bar, this kit delivers noticeably improved handling and reduced body roll compared to soft OEM rubber components.

Key Features:

• Premium Polyurethane Construction: Prothane's proprietary polyurethane compound is significantly more durable than rubber and resists breakdown from road grime, weather exposure, and oils
• Grooved Bore Design: Each bushing features a grooved inner bore engineered to retain Prothane Super Grease for quiet, squeak-free operation
• Secure Bar Grip: Polyurethane does not warp over time, maintaining a firm grip on the sway bar and delivering a performance boost similar to installing a larger-diameter bar
• Split Bushing Design: Bushings are split for easier installation without the need to remove sway bar end links
• Includes Super Grease: Kit comes with Prothane Super Grease — apply liberally to the bore during installation to prevent squeaking
• Available in Red or Black: Both colors use the same durometer (hardness); black includes a small amount of graphite which may offer additional squeak resistance
• Lifetime Warranty: Backed by Prothane's lifetime warranty against defects in materials and workmanship for the original purchaser
• Fits 30mm Bar: Designed specifically for a 30mm front stabilizer bar

Upgrading to polyurethane sway bar bushings is one of the most cost-effective suspension improvements available, delivering handling gains comparable to a full sway bar upgrade at a fraction of the cost. The Prothane 7-1133 is a direct-fit replacement that installs using the factory brackets.
