Prothane 6-1137-BL Black 30mm Front Sway Bar Bushing Kit

The Prothane 6-1137-BL is a black polyurethane front sway bar bushing kit designed as a performance upgrade over factory rubber bushings. Precision-fabricated to fit a 30mm diameter stabilizer bar, these bushings restore and improve the effectiveness of your vehicle's front anti-roll (sway) bar by providing a firmer, more consistent grip that OEM rubber simply cannot match over time.

Factory rubber bushings wear out, warp, and lose their grip on the sway bar — leading to increased body roll, clunking noises, and reduced cornering traction. Prothane's polyurethane compound resists breakdown from road grime, oils, and weather, maintaining its shape and holding the sway bar securely for the life of the vehicle. The performance improvement is comparable to installing a larger-diameter sway bar, at a fraction of the cost.

Key Features:

• Premium polyurethane construction — firmer and more durable than OEM rubber, resists oil, weather, and road grime
• Grooved bore design — engineered to retain Prothane Super Grease for smooth, quiet operation
• Split bushing design — allows installation without removing the sway bar from the vehicle
• Precision fabrication — ensures a perfect 30mm fit for proper sway bar retention
• Black color with graphite additive — helps reduce the potential for squeaking
• Includes Prothane Super Grease — pre-lube supplied for proper installation
• Made in the USA
• Lifetime warranty — Prothane guarantees against defects in materials and workmanship for as long as the original purchaser owns the vehicle

The Prothane 6-1137-BL is also available in red (part number 6-1137). For best results, apply the included Super Grease liberally to the bushing bore at installation to ensure quiet, long-lasting performance.
