Prothane 8-1138-BL Front Sway Bar Bushing Kit 25.4mm Black Polyurethane

The Prothane 8-1138-BL is a front stabilizer bar bushing kit designed as a firm, long-lasting upgrade over soft OEM rubber bushings. Constructed from premium-grade polyurethane, these bushings deliver improved chassis rigidity and more precise handling response compared to stock rubber components.

Key Features:

• 25.4mm (1 inch) bore diameter engineered for a precise, secure fit on the front sway bar
• Black polyurethane construction — the black color includes a small amount of graphite blended into the compound to aid in noise reduction
• Grooved bore design holds Prothane Super Grease for quiet, squeak-free operation
• Resistant to road grime, oils, and weathering — polyurethane does not warp or crack the way OEM rubber can over time
• Maintains a secure grip on the sway bar, preventing the loss of effectiveness caused by deflected or deteriorated rubber bushings
• Lifetime warranty — Prothane guarantees these bushings against defects in materials and workmanship for the life of the original purchaser's vehicle

Upgrading to polyurethane sway bar bushings reduces unwanted suspension deflection under cornering loads, resulting in more accurate steering response and improved body control. Prothane Super Grease is included — proper lubrication of the bore at installation is essential for quiet, long-term performance.
