Prothane 14-1120-BL Rear Sway Bar Bushing Kit 15mm Black Polyurethane

The Prothane 14-1120-BL is a 15mm rear stabilizer bar bushing kit engineered in black polyurethane as a direct performance upgrade over factory rubber sway bar bushings. Designed for the Nissan 240SX S13 (1989–1994), this kit replaces the soft, compliance-prone OEM rubber bushings with firm polyurethane that maintains its shape and grip over the long term.

Key Features:

• Premium-grade polyurethane construction — significantly firmer than stock rubber for improved suspension response and reduced body roll
• Grooved bore design — engineered to retain Prothane's Super Grease for quiet, squeak-free operation
• 15mm inner diameter — precision-fabricated to match OEM stabilizer bar dimensions for a correct, rattle-free fit
• Resists degradation — polyurethane withstands road salt, grime, oil, and weathering that cause rubber bushings to deteriorate prematurely
• Black finish — low-profile appearance that blends with factory hardware
• Compatible with larger-diameter aftermarket sway bars — also available for high-performance bar upgrades

Upgrading to Prothane polyurethane sway bar bushings keeps the stabilizer bar firmly located during cornering, preventing the bar from shifting in its mounts and restoring — or improving upon — its original anti-roll effectiveness. Backed by Prothane's Lifetime Warranty and made in the USA.
