Prothane 8-1136-BL Rear Sway Bar Bushing Kit 19mm Black Polyurethane

The Prothane 8-1136-BL is a rear sway bar bushing kit designed for the Acura RSX and RSX Type-S (2002–2006), featuring a 19mm bore to match the factory rear stabilizer bar diameter. These black polyurethane bushings are a direct upgrade over the soft OEM rubber bushings that warp, crack, and lose their grip over time.

Prothane's polyurethane compound delivers a significantly firmer, more consistent grip on the sway bar than stock rubber. Grooved bores are engineered to retain Prothane Super Grease, ensuring smooth, quiet operation throughout the bushing's life. The kit includes the bushing set and is designed for a straightforward installation using the factory mounting hardware.

Key Features:

• Designed for 19mm rear stabilizer bars
• Black polyurethane construction resists road grime, oils, and weathering that degrade rubber
• Grooved bore design retains Prothane Super Grease for quiet, squeak-free operation
• Provides a secure, warp-resistant grip on the sway bar for improved handling response
• Tighter bushing fit delivers handling improvement comparable to installing a larger sway bar
• Also fits larger-diameter aftermarket performance sway bars
• Backed by Prothane's Lifetime Warranty against defects in materials and workmanship

Upgrading to Prothane polyurethane sway bar bushings is one of the most cost-effective suspension improvements available, restoring and exceeding the original anti-roll bar effectiveness without the flex and deterioration inherent to OEM rubber components.
