Prothane 18-1127-BL Rear Sway Bar Bushing Kit Black 19mm Toyota MR2 1991-1995

The Prothane 18-1127-BL is a black polyurethane rear stabilizer bar bushing kit designed for the 1991–1995 Toyota MR2. Engineered to replace the factory rubber bushings, this kit restores and enhances sway bar performance by providing a firmer, more precise connection between the anti-roll bar and chassis.

OEM rubber stabilizer bushings wear out over time, warping and cracking under the stress of road grime, oils, and weather exposure. Prothane's polyurethane compound resists these degrading elements, maintaining a secure grip on the bar and preventing the slop and flex that rob the sway bar of its effectiveness.

Key Features:

• Fits 19mm (0.74 in.) rear stabilizer bar
• Black polyurethane construction with graphite infusion for reduced friction and squeak resistance
• Grooved bore designed to retain Prothane Super Grease for quiet, long-lasting operation
• More durable than OEM rubber — resists breakdown from oils, road grime, and weather
• Provides a performance feel similar to upgrading to a larger sway bar
• Backed by Prothane's lifetime warranty against defects in materials and workmanship
• Includes Prothane Super Grease — proper lubrication at installation is recommended to prevent squeaking

Prothane's black and red bushing variants share the same durometer (hardness), so performance is identical between colors. The black variant includes a small amount of graphite blended into the polyurethane compound, offering an added layer of squeak prevention. This kit is also available for larger-diameter high-performance sway bars.
