Prothane 18-1130 Rear Sway Bar Bushing Kit 14mm Polyurethane

The Prothane 18-1130 is a rear sway bar bushing kit designed for the 1985–1987 Toyota Corolla GTS and SR-5 (RWD). This kit replaces the factory rubber stabilizer bar bushings with precision-molded polyurethane bushings sized for a 14mm rear sway bar, restoring and improving suspension performance over worn or degraded OEM components.

Stock rubber bushings deteriorate over time — warping, cracking, and losing their grip on the bar. When this happens, the sway bar (also known as a stabilizer bar or anti-roll bar) loses effectiveness, leading to increased body roll and reduced handling response. Prothane's polyurethane formulation holds its shape and maintains a firm grip on the bar far longer than rubber, resisting breakdown from road grime, oils, and weather exposure.

Key Features:

• Fits 14mm rear sway bar — direct replacement for OEM rubber bushings
• Available in red or black polyurethane (same durometer hardness)
• Grooved bore design retains Prothane Super Grease for quiet, squeak-free operation
• Resists deterioration from road salts, grime, oils, and extreme temperatures
• Provides handling improvement comparable to installing a larger-diameter sway bar
• Backed by Prothane's Lifetime Warranty against defects in materials and workmanship
• Made in the USA

Includes Prothane Super Grease for proper lubrication during installation. For applications with an upgraded or larger rear sway bar, see Prothane 18-1131 (16mm fitment).
