Prothane 4-1135-BL 35mm Front Sway Bar Bushing Kit Black 4WD

The Prothane 4-1135-BL is a black polyurethane front stabilizer bar bushing kit designed for 4WD applications with a 35mm sway bar diameter. Prothane's premium-grade polyurethane construction delivers significantly firmer, more precise performance than the soft OEM rubber bushings they replace, restoring and improving your vehicle's roll resistance and handling response.

Each bushing features precision-machined grooved bores engineered to retain Prothane's proprietary super grease, ensuring quiet operation and long-lasting lubrication without the squeak and slop common with worn factory bushings. Prothane's exact-fit manufacturing process guarantees a direct, hassle-free installation with no modifications required.

Key Features:

• 35mm sway bar bore diameter — fits OEM and performance-diameter stabilizer bars
• Premium polyurethane construction for improved rigidity and roll control
• Grooved bore retains super grease for quiet, maintenance-friendly operation
• Black finish for a clean, understated appearance
• Precision fabrication ensures a direct OEM-replacement fit
• Significant upgrade over soft, deteriorating stock rubber bushings

This kit is the black (BL) variant of the Prothane 4-1135 series. A red version (4-1135) is also available for those who prefer a traditional Prothane look under the hood.
