Prothane 6-1129 Polyurethane Sway Bar Bushing ID End-to-End - 1-1/8

The Prothane 6-1129 is a polyurethane sway bar bushing designed to replace worn or soft OEM rubber stabilizer bar bushings. Featuring a 1-1/8" inner diameter and a 3.5" tall end-to-end bracket design, this bushing delivers improved handling response, reduced body roll, and more precise steering feel compared to stock rubber components.

Prothane's polyurethane formulation resists compression and deformation far better than rubber, ensuring the stabilizer bar stays firmly located under load. The bushing features a grooved bore engineered to retain Prothane's included Super Grease, promoting long-term quiet operation and eliminating squeaks.

Key Features:

• 1-1/8" (28.6mm) inner diameter for precise bar fitment
• End-to-end (E/E) bracket style with 3.5" bracket height
• Grooved bore retains Super Grease for squeak-free performance
• Premium polyurethane construction — more durable than OEM rubber
• Reduces body roll and improves cornering stability
• Also compatible with larger diameter high-performance aftermarket sway bars
• Manufactured in the USA
• Backed by Prothane's Lifetime Warranty

Prothane Super Grease is included with this bushing kit, ensuring proper lubrication right out of the box. This is a direct-fit upgrade for vehicles using a 1-1/8" stabilizer bar with an end-to-end style mount bracket.
