Prothane 12-1108-BL Front Sway Bar & End Link Bushing Set Black 19mm

The Prothane 12-1108-BL is a front sway bar and end link polyurethane bushing set designed as a direct replacement for the factory rubber bushings on the 1990–1997 Mazda Miata (NA). This set is engineered specifically for the stock 19mm front stabilizer bar and includes all required bushings and retaining clamps needed for a complete front sway bar bushing replacement.

Stock rubber bushings deteriorate over time, warping and cracking and losing their grip on the bar, which allows the sway bar to move excessively and reduces its effectiveness. Prothane's polyurethane compound is significantly firmer and more durable than OEM rubber, resisting breakdown from road grime, weather, and oils to deliver more consistent, precise handling with reduced deflection.

Key Features:

• Designed for the stock 19mm front sway bar on 1990–1997 Mazda Miata
• Includes front sway bar bushings, end link bushings, and retaining clamps
• Black polyurethane formulation with graphite additive for reduced noise
• Grooved bore design retains Prothane Super Grease for quiet, long-term operation
• Firmer than OEM rubber for improved handling response and reduced body roll
• Resists deformation — maintains a secure grip on the sway bar over time
• Backed by Prothane's lifetime warranty against defects in materials and workmanship
• Includes Prothane Super Grease for installation

The black color of this bushing set indicates a small amount of graphite is blended into the polyurethane, which can further reduce the potential for squeaking when properly lubricated at installation. Prothane's Super Grease is included and should be applied generously to all contact surfaces during install. MPN cross-reference: 12-1108 (red variant available separately).
