Prothane 8-1137-BL Rear Sway Bar Bushing Kit 15mm Black

The Prothane 8-1137-BL is a rear sway bar bushing kit designed for the 15mm rear stabilizer bar. Manufactured from Prothane's high-performance polyurethane material, these bushings deliver a significant upgrade over factory rubber components that are prone to warping, cracking, and losing their grip on the bar over time.

Polyurethane provides a firmer, more secure connection between the sway bar and chassis, helping the stabilizer bar maintain effectiveness through its full range of motion. This tighter grip delivers handling response comparable to installing a larger sway bar. Unlike rubber, polyurethane resists breakdown from road grime, weather, and petroleum-based fluids, ensuring long-term durability.

Key Features:

• Material: High-performance black polyurethane with graphite additive to help reduce squeaking
• Bar Diameter: 15mm rear sway bar
• Position: Rear
• Color: Black
• Includes: 2 rear sway bar bushings and Prothane Super Grease for installation
• Resists warping, cracking, and degradation from oils, weather, and road grime
• Firmer bushing feel versus OE rubber improves suspension response and handling precision
• Warranty: Lifetime warranty against defects in materials and workmanship for the original purchaser

Proper lubrication with the included Prothane Super Grease at installation is essential to prevent bushing noise. The black formulation includes a small amount of graphite in the polyurethane compound, which provides an additional layer of squeak resistance over the standard red version.
