Prothane 4-1136-BL Rear Sway Bar Bushing Kit 16mm Black Polyurethane

The Prothane 4-1136-BL is a rear stabilizer bar bushing kit engineered as a direct, performance-oriented replacement for soft OEM rubber sway bar bushings. Manufactured from premium-grade polyurethane, these bushings deliver superior resistance to road grime, oils, UV exposure, and weathering that cause factory rubber to warp, crack, and lose grip over time. Available in black, this kit is the ideal upgrade for restoring or enhancing rear sway bar function.

Key Features:

• Polyurethane construction — resists degradation from oils, road grime, and weather far better than OEM rubber
• 16mm bore diameter — precision-fit replacement for the factory rear stabilizer bar
• Grooved inner bore — designed to retain Prothane Super Grease for quiet, squeak-free operation
• Firm bushing material — provides a secure, consistent grip on the sway bar, improving handling response and reducing body roll
• Black color — with a small graphite content blended into the polyurethane to further aid in noise reduction
• Backed by a lifetime warranty — Prothane guarantees against defects in materials and workmanship for the life of the original purchaser's ownership

Worn or degraded OEM rubber sway bar bushings allow the stabilizer bar to shift in its mounts, reducing its ability to control body roll during cornering. Upgrading to Prothane's polyurethane bushings restores — and improves upon — factory sway bar performance, delivering more precise handling characteristics without sacrificing daily drivability. Prothane Super Grease is included to ensure proper lubrication during installation.
