Prothane 6-1118 Polyurethane Sway Bar Bushing Kit 1-1/8" ID Red

The Prothane 6-1118 is a polyurethane stabilizer bar bushing kit designed to replace worn or soft OEM rubber bushings on 1-1/8" (28.6 mm) inner diameter sway bars. Upgrading to Prothane's firm polyurethane construction significantly improves the effectiveness of your existing anti-roll bar — reducing body roll, increasing cornering traction, and sharpening overall handling without the expense of a full sway bar replacement.

Key Features:

• 1-1/8" (28.6 mm) Inner Diameter — engineered for a precise, tight fit on the sway bar
• Premium Polyurethane Construction — firmer than OEM rubber, maintains shape under sustained load and heat cycles
• Grooved Bore Design — internal grease channels hold Prothane's super grease for smooth, quiet, squeak-free operation
• Reduced Body Roll — keeps the stabilizer bar firmly anchored to the frame for maximum anti-roll performance
• Compatible with High-Performance Sway Bars — suitable for both OEM replacement and larger-diameter aftermarket stabilizer bar upgrades
• Red Polyurethane — Prothane's signature color; also available in black (part number 6-1118-BL)
• Made in the USA — backed by Prothane's lifetime warranty

Prothane polyurethane bushing kits are a proven, cost-effective suspension upgrade. By eliminating the flex and deflection inherent in factory rubber bushings, these bushings allow your sway bar to do its job with greater precision — delivering a noticeable improvement in cornering confidence and steering response.
