Prothane 6-1149 Front & Rear Stabilizer Bar Bushing Kit 3/4 in.

The Prothane 6-1149 is a complete front and rear stabilizer bar bushing kit designed to replace worn factory rubber bushings on the sway bar (also known as an anti-roll bar or stabilizer bar). Upgrading from soft OEM rubber to Prothane's firm polyurethane compound significantly improves the effectiveness of the existing stabilizer bar, reducing body roll and delivering more precise, responsive handling.

Key Features:

• Premium polyurethane construction — resists compression set, road grime, oil, and harsh weather that cause rubber bushings to deteriorate
• Grooved bore design — engineered to retain Prothane's super grease lubricant for smooth, quiet operation without squeaking
• 3/4 in. bar diameter — precision-sized bore ensures a firm, accurate fit on the stabilizer bar
• Front and rear kit — covers both axle positions in a single purchase
• Available in red or black — add suffix -BL to the part number for black
• Made in the USA with a lifetime warranty

Unlike stock rubber bushings that flex and deform under load, Prothane's polyurethane formula holds its shape, keeping the stabilizer bar firmly located to the chassis. This effectively maximizes the anti-roll performance of the existing bar — a cost-effective handling upgrade without replacing the bar itself. Also compatible with larger-diameter high-performance aftermarket sway bars of the same bore size.
